基于FPGA的光纤通道网络监控卡设计与实现

光纤通道（ Fibre Channel,FC）监控设备在光纤通道网络中承担着数据监控、过滤和解析等任务,对FC网络的构建、运行、故障诊断和调试起着关键性的作用。文中在对FC协议进行深入研究的基础上,提出一种在线实时过滤的光纤通道监控卡解决方案,可实现FC链路数据的实时监控。该仿真卡采用软硬件协同工作的方式,由硬件电路实现监控卡中光纤通道链路数据过滤,软件负责过滤条件配置及筛选后数据分析,克服了软件过滤数据速度慢的缺点,保证了数据过滤的实时性；同时,由于采用软件配置,使得监控卡的应用更加广泛和灵活。光纤通道网络监控卡的研制,对加速FC网络的研制有积极的推动作用。

Design and Implementation of Fibre Channel Network Monitoring Card Based on FPGA

Fibre channel monitoring device bears the tasks in fibre channel networks such as data monitoring,filtering,and analyzing,and plays a very important role in fibre channel network building,operation,fault diagnosis and debugging. Based on FC protocol for in-depth study,put forward an online real-time monitoring card solution,realizing real-time monitoring FC link data. With the method of hard-ware and software together,this hardware circuit implements link dada filtering,and software is responsible for the configuration and mo-nitoring data analysis. The use of this is to overcome the shortage of software filtering speeding,ensuring the real-time data filtering. And more,it makes the application of monitoring cards more extensive and more flexible. The design of fibre channel monitoring card has a positive role of accelerating the development of fibre channel network.
