Shared storage switch sending control method

Abstract

The invention relates to a shared storage switch sending control method. According to the method, the characteristics of shared storage are sufficiently used, during switching data frame capture, only storage addresses of switches frames and state information such as switching data frame error information, switch ports and input or output timestamp are captured, the switching data per se is not captured, the captured data reuses the switching data, the release is realized after the captured data is output from a capture port, and the difficult design problem of the traditional capture port is effectively solved.

Description

technical field [0001] The invention belongs to computer hardware technology, and relates to a method for controlling transmission of a shared memory switch. Background technique [0002] In the switch design, it is often necessary to capture the exchanged frame concerned and output it from the capture port, and at the same time, it is required to output the frame's error status, input port number and input time stamp, or output port number and output time stamp. In the traditional input and output capture design, a capture data channel is often built between the input port, output port and capture port. When the data frame to be captured is input from the input port, it is output to the capture output port, or when the data frame to be captured When the frame is output from the output port, it is output to the capture output port. Although this design can also achieve control, it still has the following defects: [0003] 1. It is necessary to add a buffer at the capture ou...

Problems solved by technology

[0003] 1. It is necessary to add a buffer at the capture output port to store the captured frame data, which makes the switching circuit structure bloated
