Packet Capture and Generating at High Speed with DMA
|
Abstract:
Network test and measurement is one of most important methods to find out characteristic of traffic and understand application performance.It is key issue to perform network measurement for high speed link.An Ethernet frame capture and generating method has been proposed in BIOS with Direct Memory Access (DMA) for network processor.This method has been implemented on network processor of BCM 1250.It has been showed from experiment the performance of packet capture and generation with this method on BCM 1250 has been improved double over on embedded linux.
