Abstract

The invention discloses a packet sniffing method and device in a high-speed interconnection system. In the invention, an output port of SRIO (Serial RapidIO) exchange equipment, i.e. high-speed interconnection equipment, is preset to be a packet sniffing port, and when a sending processor needs to send a packet to a target processor, the method comprises the following steps of: mirroring the packet required to be sent to the target processor to a processor connected with a packet sniffing port by the sending processor; filtering the received packet by the processor connected with the packet sniffing port according to a preset packet sniffing filtering condition; and sending the packet required to be captured to a preset packet sniffing host for analyzing. The invention realizes a quick and high-efficiency packet sniffing function in a port mirroring mode on the basis of not influencing the efficiency of the sending processor and the receiving processor.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for capturing packets in a high-speed interconnection system. Background technique [0002] RapidIO (high-speed interconnection) and its currently widely used Serial RapidIO (serial high-speed interconnection) standard are becoming a protocol for the interconnection of various parts of embedded systems. It has the characteristics of high bandwidth and low overhead and is used for microprocessors, DSP (digital Singnal processor, digital signal processor), communication and network processors, and the transmission of data and control information between I / O devices in embedded systems. [0003] The internal interconnection structure of the existing SRIO system such as figure 1 As shown, it includes 3 processors and an SRIO switching device. Among them, there is a large amount of data interaction on the media plane between the processor CPU0 and the proce...
