[Abstract]:With the rapid development of network technology, optical fiber channel (Fibre Channel,FC) protocol provides a high reliability, low cost and real time solution for high speed communication network. The switch is the basis and core of the whole network data exchange. The switch in the FC switching network applies the switching technology and the mirror technology, among which the mirror technology is the monitoring technology. In switching networks, it refers to the replication of messages from the designated port of the switch or messages conforming to the protocol to the destination port. The main research work of this paper is as follows: (1) according to the existing FC switch structure, the soft core of Monitor,MT port in FC switch protocol processing chip is designed and implemented to support the input data monitoring of FC switch chip. Output data monitoring and information ID (Identifier) monitoring and other functions, in addition to support between the network management node frame transceiver function, monitoring and routing scheme online dynamic loading. (2) according to the MT port needs to achieve the function, Information ID query control module, monitoring data buffer write control module, monitoring data scheduling module, The monitoring data sending module is designed and implemented in MT port frame sending module and MT port frame receiving module. (3) after the module design verification is completed, the module is interlinked and integrated. The function simulation and performance test of MT port are carried out on virtual simulation platform and FPGA verification platform respectively. In this paper, the functional simulation and traffic monitoring of the designed MT port are carried out. The results show that the new intelligent monitoring mode can not only be used for network supervision and troubleshooting, but also for traffic statistics. In addition, its function is completely independent of the line card port and network management node, and does not occupy the switching bandwidth resources, network management and configuration resources, and can be flexibly applied to the construction process of FC switching network. It greatly facilitates the network data analysis and fault location, and provides an important support for the application of FC switching network, and has a wide application prospect.
