GigE Vision Inter-Packet Delay and Packet Size Tuning: How to Prevent Burst Traffic, Switch Buffer Overflow and Frame Loss in Multi-Camera Ethernet Vision Networks

A multi-camera GigE Vision network can have enough calculated average bandwidth and still lose image packets when several cameras transmit large bursts toward the same Ethernet switch, uplink or host at nearly the same time. The underlying problem is often not the total number of bytes generated during one second but the way those bytes are distributed within that second. If several cameras release packets aggressively after exposure or trigger events, instantaneous traffic can converge on one shared network resource faster than that resource can forward it. Switch output queues begin to fill, packet buffers absorb the temporary excess, and packets can eventually be discarded if the burst lasts longer than the available buffering can tolerate. This is where GigE Vision inter-packet delay, camera packet size and transmission timing become important engineering parameters rather than optional network settings.

Inter-packet delay introduces controlled spacing between packets transmitted by a camera, allowing an OEM to reshape an aggressive packet burst into a more manageable stream. Packet-size tuning controls how much image payload is carried in each transmitted packet, influencing packet count, protocol overhead and host packet-processing demand. These two settings solve different parts of the Ethernet traffic problem and should be tuned together only after the fundamental network architecture has sufficient bandwidth. Neither setting creates additional physical Ethernet capacity, and neither can permanently correct an uplink that is mathematically too small for the sustained aggregate camera load. Their value is in controlling how available capacity is consumed so that simultaneous cameras do not unnecessarily overwhelm shared switch queues or host receive resources.

The Kyptec Automation® GigE Ethernet Cable portfolio forms the physical RJ45 transmission path for compatible industrial GigE camera networks and includes straight CAT 6, right-angle CAT 6, screw-retained CAT 6 and CAT 8 connectivity options. Cable category, conductor construction, connector geometry and installed length should be selected independently from camera packet timing, but both the physical connection and Ethernet traffic configuration ultimately need to perform reliably together in the completed machine. A correctly specified cable provides the physical transport path; inter-packet delay and packet-size tuning determine how camera traffic is presented to the shared network resources connected through that path.

Why Average GigE Camera Bandwidth Does Not Reveal the Entire Traffic Problem

An average network calculation tells the OEM how much image data the cameras generate over a period of time, but it does not describe exactly when each packet arrives at a shared switch output. Consider several cameras whose combined average traffic remains below the rated capacity of a host uplink. If those cameras transmit continuously and their packets are naturally distributed in time, the switch may forward the traffic with very little queue buildup. If the same cameras are triggered simultaneously and each begins transmitting a large image immediately, their traffic can converge in concentrated bursts. For a short interval, the total ingress rate directed toward one output can exceed the rate at which that output can transmit packets, even though the long-term average remains technically acceptable.

The switch must temporarily store that excess traffic. If the burst finishes before the available queue is exhausted, all packets can eventually be transmitted and the host receives complete images. If the queue fills first, packets arriving after the buffer is exhausted can be dropped. This is why an engineer can calculate a seemingly acceptable average network load and still observe intermittent GigE Vision frame loss during synchronized acquisition.

Inter-Packet Delay Controls the Spacing Between Camera Packets

Inter-packet delay is a timing interval inserted between successive packets transmitted by the camera. Instead of releasing packet after packet as rapidly as the camera interface permits, the camera waits for the configured interval before transmitting the next packet. The result is a lower instantaneous packet transmission rate and a longer period over which the complete image is delivered.

Conceptually, if one camera transmits a frame as an extremely compact burst, the switch receives a high concentration of packets over a short interval. Introducing delay spreads the same image data over a longer interval. The total number of image bytes does not necessarily change, but the traffic becomes less bursty. This can give a shared switch output more time to forward earlier packets before additional packets arrive, reducing the probability that its queue reaches capacity.

The engineering tradeoff is that a longer inter-packet delay also extends the time required to transfer the complete image. Excessive delay can therefore reduce achievable throughput or increase image-transfer completion time. The objective is not to maximize the delay setting but to find the smallest practical delay that controls congestion while preserving the required acquisition performance.

Inter-Packet Delay Does Not Reduce the Size of the Image

Traffic shaping should not be confused with reducing camera bandwidth by changing image content. If a camera generates a 5 MB image, adding inter-packet delay does not make that frame smaller. It simply changes the temporal distribution of the Ethernet packets carrying those 5 MB. The same distinction applies to a continuous camera stream: pacing may reduce instantaneous burst intensity, but the underlying average image-data requirement still needs to fit within the available network architecture.

This matters when OEMs diagnose multi-camera networks because a heavily oversubscribed link cannot be repaired by indefinitely increasing packet delay. If the cameras collectively generate more sustained traffic than the shared output can physically transmit, a queue will ultimately continue growing until packets are lost regardless of how smoothly the traffic begins. Inter-packet delay is most effective when the network has enough average capacity but experiences short-term congestion caused by simultaneous or uneven packet arrival.

Packet Size Determines How Many Packets Must Carry Each Camera Frame

Packet size introduces a second dimension to traffic tuning. Smaller packets require a larger number of packets to transport the same image payload, while larger supported packets carry more image data in each transmission. A larger packet size can reduce packet count and proportional protocol overhead, while also reducing the number of packet-processing events presented to the host NIC and operating system. This is why appropriately configured jumbo frames can often improve GigE Vision transport efficiency when the camera, Ethernet switch and NIC all support the selected frame size.

However, larger packets themselves do not prevent burst traffic. A camera can transmit large packets back-to-back just as aggressively as smaller ones. Packet size therefore addresses packet efficiency, while inter-packet delay addresses transmission pacing. A well-engineered multi-camera network may use both: a larger validated packet size to reduce unnecessary packet count and a carefully selected inter-packet delay to prevent simultaneous cameras from flooding the same switch output.

Packet Size and Inter-Packet Delay Should Be Treated as Separate Controls

It is useful to separate the two settings conceptually because they affect different behaviors. Increasing packet size generally reduces the number of packets needed for each image and can improve protocol efficiency, while increasing inter-packet delay creates more time between packets and lowers the short-term packet transmission rate. An OEM should therefore avoid assuming that jumbo frames eliminate the need for traffic pacing or that inter-packet delay makes packet-size optimization irrelevant.

A network may benefit from larger packets but still experience switch buffer overflow because several cameras transmit those large packets simultaneously. Conversely, increasing inter-packet delay may control congestion while a small MTU continues to generate unnecessarily high packet-processing overhead at the host. The correct combination depends on the actual cameras, trigger timing, switch, NIC, host architecture and required image-transfer time.

Why Simultaneously Triggered Cameras Create the Strongest Burst Condition

Synchronized acquisition is one of the most common reasons that otherwise adequate Ethernet networks experience momentary congestion. When several cameras receive the same trigger, they can complete exposure at approximately the same time and begin transmitting image data shortly afterward. If every camera attempts to use its Ethernet link aggressively, a switch may receive traffic simultaneously from several ingress ports, all destined for one host-facing output.

For example, four camera ports can each be receiving traffic while one uplink must forward the combined packets toward the industrial PC. Even if the final average data volume fits within the long-term host capacity, the short synchronized burst can exceed what the output queue can immediately drain. Inter-packet delay can provide temporal spacing so the cameras do not place their complete transmission demand on that shared output at the same moment.

Switch Buffer Overflow Begins When Ingress Temporarily Exceeds Egress

A switch output buffer is essentially temporary storage used when packets destined for an output arrive faster than that output can immediately transmit them. If incoming traffic drops back below the output capacity quickly enough, the queue drains and no packets need to be discarded. If additional packets continue arriving while the queue is already full, packet loss becomes possible.

This explains why simply buying a switch with “large buffers” is not the only solution. Buffer memory provides time, not additional permanent bandwidth. A larger buffer can absorb a larger or longer burst, but a traffic-shaping strategy can reduce the burst itself. For multi-camera GigE Vision systems, the most robust architecture combines adequate physical link capacity, suitable switch buffering and camera transmission settings that avoid unnecessary packet concentration.

Inter-Packet Delay Can Reduce Peak Queue Occupancy

When camera packets are spaced farther apart, the switch obtains more opportunity to transmit one packet before the next arrives from the same camera. Across several simultaneously transmitting cameras, even modest pacing can lower the peak rate at which the shared output queue fills. Instead of receiving several concentrated packet trains at once, the switch can see a more distributed traffic pattern.

The improvement should be validated empirically because the optimal setting depends on the complete network. Too little delay may leave the original burst largely unchanged, while too much delay can extend frame-transfer time unnecessarily. The practical objective is to increase delay progressively while monitoring packet loss, switch drops and acquisition timing until the network becomes stable with appropriate operating margin.

Do Not Start Tuning Until the Aggregate Bandwidth Calculation Is Valid

Traffic shaping cannot replace capacity planning. Before tuning inter-packet delay, the OEM should confirm that the total sustained data generated by the cameras fits through every shared link in the network. If four cameras collectively require substantially more data rate than the host uplink can sustain, the correct solution is an architectural change such as distributing traffic across additional network interfaces or providing a higher-capacity compatible uplink, not merely stretching the packet spacing.

A useful diagnostic principle is that inter-packet delay addresses a timing problem when sufficient long-term bandwidth already exists. If sustained traffic itself exceeds capacity, the system has a bandwidth problem. Keeping these two cases separate prevents extensive tuning of a network that is fundamentally undersized.

The Correct Delay Depends on Camera Traffic, Not Camera Count Alone

Two four-camera systems can require very different pacing settings because camera count does not determine Ethernet load by itself. Resolution, transmitted pixel format, frame rate, trigger pattern, packet size and the timing relationship among cameras all influence how much traffic reaches the shared resource. Four relatively low-data-rate cameras may need little or no added inter-packet delay, while four high-resolution cameras triggered simultaneously can require careful traffic shaping.

The OEM should therefore avoid using a fixed delay value simply because another machine uses the same number of cameras. Inter-packet delay should be tuned to the actual traffic architecture of the machine being built.

Staggered Inter-Packet Delay Can Help Distribute Multiple Camera Streams

In some systems, cameras can be configured so that their packet transmission patterns do not align perfectly. The objective is to prevent all camera packet trains from reaching the shared switch output at exactly the same moments. Depending on camera capabilities and network design, engineers may use different transmission delays or other timing controls to spread traffic more evenly.

The exact configuration method varies by camera and software, so one universal numeric setting should not be prescribed. What matters is the underlying principle: multi-camera traffic is easier for the network to handle when packet arrival is distributed over time instead of concentrated into synchronized bursts.

Inter-Packet Delay Can Increase Frame Transfer Time

Every additional delay inserted between packets contributes to the time required to transfer the complete image. If one image requires hundreds or thousands of Ethernet packets, even a relatively small per-packet delay can accumulate across the complete frame. This can influence when the image becomes fully available to the host and may affect the maximum sustainable acquisition rate when delay is configured too aggressively.

Therefore, the OEM should test not only whether packet loss disappears but also whether the final transfer time remains compatible with the camera cycle. The correct configuration achieves stability without sacrificing more throughput or latency than necessary.

Calculate the Tradeoff Between Stability and Transmission Time

A practical tuning sequence should begin with a known packet size supported throughout the network, then establish stable single-camera transmission before adding additional cameras. As camera count increases, the engineer can monitor switch output drops and host packet loss. If congestion appears only during simultaneous streaming, inter-packet delay can be increased gradually while acquisition timing is measured.

The correct endpoint is reached when packet loss remains absent under the intended worst-case traffic pattern and sufficient performance margin remains. Tuning should not stop at the first setting that appears to work for a short test; repeated acquisition and sustained operation should confirm that queue behavior remains stable.

Jumbo Frames Can Reduce Packet Count Before Delay Is Added

If the complete network supports larger Ethernet frames, a larger validated packet size can reduce the number of packets required for each image. This can lower per-packet protocol overhead and host-processing activity before inter-packet delay is introduced. Fewer packets also means the configured delay is applied fewer times per image, which can influence total frame-transfer duration.

This creates an important interaction between the two parameters. A system using small packets may need thousands of delay intervals per image, while one using larger supported packets can transfer the same image using substantially fewer packets. Consequently, packet-size selection should normally be established before the final inter-packet delay is optimized.

Do Not Assume the Maximum Jumbo Frame Is Always the Best Packet Size

Although larger packets often improve efficiency, the largest numerical packet setting is only useful when the entire path supports it reliably. The camera, switch and NIC must all accept the configured frame size. A mismatch can create packet loss that is completely unrelated to switch burst congestion.

The OEM should therefore establish a known-good maximum supported packet size across the complete path and then tune inter-packet delay from that stable baseline. If packet loss begins immediately after increasing frame size, packet compatibility should be investigated before adding more delay, because pacing cannot repair a device that rejects oversized frames.

Inter-Packet Delay Can Reduce Pressure on a Shared Host NIC

Switch buffers are not the only resources affected by bursty camera traffic. A host NIC also has finite receive queues and must deliver incoming packets to the operating system. Several cameras transmitting intense packet bursts through one host interface can create short periods of very high packet arrival, particularly when all cameras are synchronized.

Pacing the camera traffic can spread those receive events over a longer period and may reduce pressure on the NIC and host network stack. This does not increase the NIC's physical link capacity, but it can make the incoming workload more manageable when the root problem is packet burstiness rather than insufficient sustained bandwidth.

CPU Load Can Also Benefit From Appropriate Packet Size

Inter-packet delay primarily changes timing, while larger supported packet sizes can reduce packet-processing frequency. A host that receives the same amount of image data in fewer packets may perform less per-packet work. This can be particularly relevant when several cameras share one industrial PC and the CPU must simultaneously handle network reception, frame reconstruction and image processing.

The two tuning tools therefore complement each other: packet size can improve processing efficiency and inter-packet delay can distribute that packet activity more evenly in time. Neither should be expected to compensate for a host whose overall processing architecture is fundamentally inadequate for the image workload.

Direct Camera-to-NIC Links May Need Less Traffic Shaping Than Shared Switch Networks

A camera connected directly to its own dedicated NIC port does not compete with several other camera streams for the same switch egress queue. As a result, inter-packet delay may be less important for preventing switch buffer overflow in that topology. Packet-size optimization can still matter for protocol efficiency and host processing, but the shared congestion point has been reduced.

By contrast, several cameras feeding a common Ethernet switch and one host uplink create a natural convergence point where traffic timing matters considerably more. The need for inter-packet delay should therefore be determined by topology rather than applied automatically to every GigE camera.

Ethernet Cable Selection Remains Independent From Packet Pacing

The Kyptec Automation® Industrial GigE Ethernet Cable (CAT 6) With RJ-45 Connectors provides a straight CAT 6 RJ45 connection for compatible camera-to-network paths. The camera's inter-packet delay is not created by the cable; it is generated by the camera's Ethernet transmission configuration. The cable carries the resulting packet stream according to the active network interface.

This separation is important during purchasing because choosing a different cable connector shape does not alter switch queue behavior. Physical cable construction should be selected according to category, installed length, connector arrangement and machine layout, while packet pacing should be selected according to camera traffic and shared network behavior.

Right-Angle GigE Cables Solve Geometry Without Changing Packet Timing

Where camera mounting leaves insufficient room for a straight RJ45 exit, the Kyptec Automation® Industrial GigE Ethernet Cable (CAT 6), RJ-45 Connectors, Right Angle UP Direction or right-angle DOWN configuration can provide a more suitable camera-side cable path. The chosen UP or DOWN orientation has no inherent effect on inter-packet delay, packet size, switch buffer depth or network bandwidth.

This allows the OEM to optimize physical installation and packet behavior independently while validating both together in the completed machine.

Screw-Retained GigE Cables Address Connector Retention Rather Than Congestion

For cameras designed around compatible horizontal screw retention, the Kyptec Automation® GigE Machine Vision Camera Cable (CAT 6), RJ-45 Connectors, With Screw Type provides a straight retained connection, while right-angle UP screw-type and right-angle DOWN screw-type versions provide directional alternatives.

These configurations can improve mechanical connection security where required, but screw retention does not change camera packet transmission timing and cannot prevent switch buffer overflow caused by synchronized network traffic. The mechanical and network problems should remain clearly separated during both design and troubleshooting.

CAT 8 Does Not Eliminate the Need for Inter-Packet Delay on a Lower-Speed Active Network

The Kyptec Automation® Industrial GigE Ethernet CAT 8 Cable With RJ-45 Connectors provides a higher cable-category option for compatible Ethernet infrastructure, but the cable category does not determine how aggressively a GigE camera transmits packets. If the active camera and switch ports operate at a lower Ethernet rate and several cameras converge on one constrained output, the same traffic-shaping principles still apply.

CAT 8 should therefore be selected when its cable capabilities are relevant to the network requirement, not as a substitute for packet timing configuration. Physical cable capability, active interface speed and inter-packet delay are three separate parameters.

Validate Inter-Packet Delay With the Real Multi-Camera Trigger Pattern

A network should be tuned using the actual acquisition timing that the production machine will experience. Testing cameras one at a time or allowing them to free-run asynchronously can hide congestion that appears when the final machine triggers all cameras together. Final commissioning should reproduce the approved number of cameras, resolution, frame rate, packet size, trigger pattern, switch topology, host NIC and cable lengths.

The test should then monitor incomplete frames, packet loss, switch output drops and host receive behavior over a sufficiently representative operating period. The objective is not merely to find a delay value that eliminates one observed failure but to prove that the network retains adequate margin under the intended worst-case traffic pattern.

Frequently Asked Questions

1. What is inter-packet delay in a GigE Vision camera?

Inter-packet delay is a configurable waiting interval between Ethernet packets transmitted by a compatible GigE camera. Increasing the interval spreads an image transmission over a longer period instead of allowing the camera to transmit packets as aggressively as possible. This can reduce temporary congestion when several cameras send traffic toward the same switch output or host NIC, but it does not reduce the number of image bytes produced by the camera or increase the physical bandwidth of the Ethernet connection.

2. Why would a GigE Vision camera need inter-packet delay?

Inter-packet delay is useful when camera traffic is sufficiently bursty that shared switch buffers or host receive resources become overloaded even though the long-term bandwidth calculation appears acceptable. By pacing the packets, the camera gives downstream equipment more time to forward or process earlier packets before additional ones arrive. The setting is particularly relevant to multi-camera systems where several cameras transmit nearly simultaneously.

3. Can inter-packet delay prevent dropped frames in a multi-camera GigE network?

It can prevent frame loss when the underlying cause is short-term packet congestion and the network has sufficient sustained capacity. If packets are being dropped because several camera bursts temporarily exhaust a switch output queue, controlled pacing may reduce peak queue occupancy enough to maintain complete frame delivery. It cannot correct a network whose sustained aggregate traffic already exceeds the capacity of a shared Ethernet link.

4. Does increasing inter-packet delay reduce GigE camera bandwidth?

It reduces the rate at which packets are released during the transmission burst and can extend the time required to transfer a frame, but it does not reduce the amount of data contained in that frame. If the delay becomes too large, it can ultimately restrict sustainable image-transfer throughput, which is why the OEM should use the minimum practical delay that achieves reliable operation rather than simply maximizing the setting.

5. How do I know if my GigE packet loss is caused by burst traffic?

A strong indication is that individual cameras work correctly but packet loss appears when several cameras are triggered or stream simultaneously, especially when aggregate average bandwidth still appears reasonable. If spreading camera transmission timing or introducing modest inter-packet delay reduces switch output drops without changing the physical cables, burst congestion becomes a much stronger explanation.

6. What is the relationship between packet size and inter-packet delay?

Packet size determines how much image data is carried per packet, while inter-packet delay determines the time spacing between those packets. Larger supported packets usually mean fewer packets are required per image, whereas additional delay spreads those packets over time. Because delay is applied repeatedly across the packet stream, packet size can also influence how much total transfer-time effect a particular delay value has.

7. Should I enable jumbo frames before tuning inter-packet delay?

When the camera, switch and NIC support a compatible larger frame size, establishing an efficient and stable packet size before final delay tuning is generally sensible because it reduces packet count and defines the packet stream that will actually be paced. However, jumbo frames should never be enabled blindly. End-to-end compatibility must first be confirmed so that MTU mismatch is not mistaken for a congestion problem.

8. Can jumbo frames alone stop switch buffer overflow?

Not necessarily. Larger packets can reduce packet count and protocol overhead, but several cameras can still transmit their packets simultaneously and create a concentrated burst at one switch output. Packet-size optimization improves transport efficiency, while inter-packet delay controls transmission pacing. Depending on the network, both may be useful.

9. How does synchronized camera triggering cause Ethernet congestion?

When multiple cameras are triggered together, they can finish exposure and begin image transmission at nearly the same time. Their individual Ethernet streams may then converge on one shared switch output or host NIC. The instantaneous arrival rate at that shared resource can temporarily exceed its forwarding capacity, causing queue buildup even when long-term average bandwidth appears acceptable.

10. Can a bigger switch packet buffer eliminate the need for inter-packet delay?

A larger buffer can absorb a larger temporary traffic burst, but it does not create additional sustained bandwidth. Traffic shaping may still be valuable because it reduces the burst presented to the buffer rather than relying entirely on storage inside the switch. A robust network should have adequate bandwidth, suitable buffering and sensible packet transmission behavior rather than depending on one parameter alone.

11. Can inter-packet delay help when multiple GigE cameras use one NIC?

Yes, when the NIC experiences short periods of very concentrated packet arrival from several cameras. Pacing can distribute those packets over a longer interval and may reduce receive-queue pressure. However, if the combined sustained camera traffic exceeds the NIC's link capacity or the host cannot process the overall image workload, inter-packet delay cannot solve that fundamental bottleneck.

12. Why can too much inter-packet delay reduce camera performance?

Every additional interval between packets increases the elapsed time needed to deliver a complete frame. When an image is composed of many packets, those intervals accumulate. If the total transfer time becomes too long relative to the required acquisition rate, the camera may no longer deliver images at the desired throughput. The setting should therefore be optimized for stability and transfer time together.

13. Should every camera in a multi-camera network use the same inter-packet delay?

Not necessarily. The appropriate configuration depends on how traffic from each camera contributes to the shared network load and on what timing controls the camera system provides. In some architectures, different pacing or transmission timing can distribute packet arrival more evenly. The OEM should validate the complete traffic pattern rather than assuming that identical numerical settings automatically produce the best network behavior.

14. Does inter-packet delay change the Ethernet cable requirement?

No. Inter-packet delay is a network transmission parameter generated by the camera and does not change whether the installation requires CAT 6 or CAT 8, a straight RJ45 connector, a right-angle connector or screw retention. The Kyptec Automation® GigE Ethernet Cable configuration should be selected from the physical network and installation requirements, while packet delay is tuned from traffic behavior.

15. Can a right-angle GigE camera cable improve packet timing?

No. The Kyptec Automation® right-angle UP and DOWN CAT 6 configurations change the physical cable exit at the camera and can improve installation geometry where rear clearance is restricted, but they do not generate inter-packet delay or alter camera packet scheduling. Packet timing is controlled by the active network devices and camera configuration.

16. Does a screw-lock RJ45 GigE cable prevent switch buffer overflow?

No. Screw-retained Kyptec Automation® CAT 6 cable configurations can help preserve mechanical connector engagement on compatible camera interfaces, but switch buffer overflow occurs because packets arrive at a shared output faster than they can be forwarded. Mechanical retention and Ethernet congestion are different engineering problems and require different solutions.

17. Will upgrading to CAT 8 remove the need to tune packet delay?

Not automatically. The Kyptec Automation® CAT 8 RJ45 cable provides higher cable-category capability for compatible infrastructure, but camera packet pacing is governed by the active Ethernet architecture. If the camera, switch or NIC still operates through a shared link where simultaneous streams create bursts, inter-packet delay may remain relevant regardless of the cable category.

18. What should an OEM validate before finalizing GigE Vision inter-packet delay?

The OEM should first confirm that sustained aggregate camera bandwidth fits through every shared network link, establish a packet size supported by the camera, switch and NIC, reproduce the real multi-camera trigger pattern and then adjust inter-packet delay while monitoring packet loss, switch queue drops, frame completeness and image-transfer time. Final validation should use the intended Kyptec Automation® GigE Ethernet Cable configuration, production cable lengths and complete host architecture so the qualified settings represent the actual machine rather than a simplified bench test.

Conclusion

GigE Vision inter-packet delay and packet-size tuning are most valuable when a multi-camera Ethernet vision network has enough sustained bandwidth but experiences short-term congestion because several camera streams reach the same shared network resource at nearly the same time. Packet size determines how efficiently each image is divided into Ethernet packets, while inter-packet delay controls how rapidly those packets are released. Larger validated packets can reduce packet count, protocol overhead and host packet-processing demand, while carefully selected inter-packet delay can spread traffic sufficiently to reduce switch output queue buildup and host receive bursts. These controls therefore complement each other, but neither should be mistaken for additional physical Ethernet bandwidth.

The correct tuning sequence begins with architecture rather than settings. OEMs should calculate aggregate image traffic, verify the capacity of every shared link, establish an end-to-end packet size that the camera, switch and NIC support, reproduce the real synchronized trigger pattern and only then introduce packet pacing where congestion evidence shows it is needed. Inter-packet delay should be increased gradually and evaluated against both packet-loss reduction and total frame-transfer time. If the network remains unstable because sustained traffic itself exceeds the available capacity, the architecture needs greater bandwidth or better traffic distribution rather than progressively larger delay values.

The Kyptec Automation® GigE Ethernet Cable portfolio provides the physical Ethernet connection around which this controlled network architecture can be built. OEMs can select the straight CAT 6 RJ45 cable, right-angle UP CAT 6, right-angle DOWN CAT 6, straight screw-retained CAT 6, right-angle UP screw-retained CAT 6, right-angle DOWN screw-retained CAT 6 or CAT 8 RJ45 cable according to the required Ethernet category, camera-side geometry, retention requirement and installed route. By combining a controlled physical cable specification with validated packet size and inter-packet delay settings, OEMs can reduce unnecessary packet bursts, protect switch and host queues from avoidable congestion and create more repeatable multi-camera GigE Vision data transmission across production machines.
