【摘要】：随着网络技术的快速发展,光纤通道(Fibre Channel,FC)协议为高速通信网络提供了一种高可靠性、低成本和实时性强的解决方案,能够满足现今高速交换网络系统的需求。而交换机是整个网络数据交换的基础和核心,在FC交换网络中的交换机应用了交换技术和镜像技术,其中镜像技术即是监控技术,其在交换网络中是指将交换机指定端口的报文或者符合协议的报文复制到目的端口。本文的研究工作主要有:(1)根据现有的FC交换机结构,设计并实现了FC交换机协议处理芯片中监控(Monitor,MT)端口的软核,用以支持FC交换机芯片输入数据监控、输出数据监控和信息ID(Identifier)监控等功能,此外,还支持与网络管理节点之间的帧收发功能、监控与路由方案的在线动态加载。(2)根据MT端口所需要实现的功能,对信息ID查询控制模块、监控数据缓冲区写控制模块、监控数据调度模块、监控数据发送模块、MT端口帧发送模块和MT端口帧接收模块进行了设计与实现。(3)在模块化设计验证完成后,进行了模块的互联集成,并分别在虚拟仿真平台和FPGA验证平台下进行了MT端口的功能仿真和性能测试。本文主要对所设计的MT端口进行了功能性仿真和监控流量测试,结果表明,这种新的智能监控模式不仅能够用于网络监管和故障排除,而且可用于流量统计。除此之外,其特点是功能完全独立于线卡端口与网络管理节点,且不占用交换带宽资源、网络管理和配置资源,可灵活应用于FC交换网络的构建过程,极大的便利了网络数据分析以及故障定位,为FC交换网络的应用推广提供了重要支撑,具有广泛的应用前景。
[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.
