基于共享存储的FC交换单元的研究和实现

摘要

针对光纤通道(FC)交换机,研究并设计了一种基于共享存储器的交换结构,重点对FC交换单元的组成、调度、内部帧、多播和流控等关键技术进行了描述,并基于Xilinx平台进行了设计和验证,验证了交换单元的有效性.该研究为实现自主化的FC交换机产品奠定了有效的基础,也对采用FPGA实现各种网络协议具有借鉴意义.%A kind of shared-memory exchange structure is researched and designed aiming at fiber-channel switch. The key technologies of the fiber channel exchange unit are described, including composition, scheduling, internal frame, multicast and flow control. The validity of the exchange unit is verified based on Xilinx. It lays the foundation of self-design of fiber channel switch products, and is useful to realize varities of network protocols by FPGA.
