First of all, we need to understand what Bypass is. Let's take a simple example: Everyone knows that network security devices are generally used between two or more networks, such as between an intranet and an extranet. The application in the network security device will analyze the internal information on the network packet, and after determining that there is no threat, it will pass the packet out according to certain routing rules. However, the premise of existence is that there is no problem with the network communication equipment. When the network security device freezes, loses power, or other failures, the networks connected to this device will lose contact with each other. At that time, if we still need to require that the networks be connected, this requires Bypass to come forward.

Wafer Inspection GigE Frame Grabbers: Jumbo Frames, RDMA and Zero Frame Loss

Wafer defect detection and critical dimension measurement run on machine vision — and every dropped frame is a defect that never gets seen. GigE frame grabber cards with jumbo frames and RDMA are how inspection systems make frame loss impossible.

The frame-loss problem in wafer inspection

Defect inspection cameras on wafer stations run continuously at high frame rates. A standard Ethernet link with small frames and CPU-based receive paths can drop packets when the bus or the OS scheduler hiccups. In inspection, one lost frame can mean one undetected scratch — which becomes a failed die, or worse, a field failure. Frame-loss-free acquisition is not a luxury; it is the specification.

Jumbo frames: more data per packet

Jumbo frames enlarge the per-packet payload from the standard 1,500 bytes to 9,000 bytes or more. Fewer packets per image means fewer interrupts, less CPU work per megabyte, and measurably higher throughput on the same link. For a 5-megapixel camera at full frame rate, jumbo frames can be the difference between keeping up and falling behind.

RDMA: bypass the CPU entirely

RDMA moves image data from the NIC directly into application memory, skipping the kernel and the CPU. Latency drops, CPU load drops, and multi-camera concurrency stops competing for processor time. LR-LINK RDMA frame grabbers are in development; today the production line covers jumbo-frame GigE capture from 1G through 10G with mature, field-proven controllers.

Choosing the right rate: 1G / 2.5G / 5G / 10G

Match the NIC tier to total camera throughput: calculate resolution × frame rate × bit depth, then plan for 70% of theoretical bandwidth as headroom. A single camera at gigabit rates fits a 1G or 2.5G card; mainstream 5-megapixel multi-camera stations choose 5G; high-resolution, high-frame-rate inspection with several cameras needs 10G. LR-LINK also offers PoE+ frame grabbers that power the camera and acquire images on the same cable — simpler cabling, fewer failure points.
