Embodiment Construction

[0050] The switching of the monitoring scheme includes the switching of the working mode of the monitoring port, the switching of the input monitoring port number, and the switching of the output monitoring port number. The implementation scheme of monitoring switching is as follows: figure 1As shown, there are three independent control state machines and data gating logic, and the data gating logic performs data gating under the control of their respective state machines, while ensuring the integrity of the data frame. In the following, the corresponding implementation manners will be described respectively for these three aspects.

[0051] 1. Switching of monitoring port working mode

[0052] The monitoring port has four working modes: normal communication mode (2’h0), input monitoring mode (2’h1), output monitoring mode (2’h2) and message monitoring mode (2’h3). Such as figure 1 As shown, in normal communication mode, select normal communication data for output; in input...

Abstract

The invention belongs to the technical field of computer communication, and particularly relates to a monitoring scheme switching method based on an FC switch. According to the monitoring scheme switching method based on the FC switch, a series of registers, especially a register used for detecting the integrity of a current data frame during switching and a register used for controlling data gating are set, switching is only carried out when the data frame is integral, and then a monitoring port of the switch can capture the integral data frame. The monitoring scheme switching method based on the FC switch has the advantages that control can be achieved easily, and hardware logic can be realized easily; the integrity of the monitoring data frame can be guaranteed during monitoring scheme switching; a normal monitoring function is not affected when monitoring scheme switching is not carried out.

Description

technical field [0001] The invention belongs to the technical field of computer communication, and in particular relates to a monitoring scheme switching method based on an FC switch. Background technique [0002] The FC network has the characteristics of high bandwidth, low delay and high reliability, and is very suitable for use in distributed real-time systems that have high requirements for real-time data transmission. [0003] As the core component of the entire FC network, the FC switch not only has data communication functions such as unicast, multicast, and broadcast, but also has monitoring functions, and analyzes and locates problems by capturing network transmission data. Each monitoring port of an FC switch has four working modes, including normal communication mode, input monitoring mode, output monitoring mode and message monitoring mode. In the normal communication mode, the monitoring port is used as an ordinary communication port without monitoring function...
