Multiple Routing Choice Design And Simulation Based On FPGA

In recent years, along with the network popularization and the rapid developmentof network technology, the number of people using the network, the number of thehost and the network traffic is in constant growth. In addition, people are no longersatisfied with the single communication mode, comprehensive requirement ofvoice,images and data become more and more obvious,in this case,the morecomprehensive business network will inevitably become a development trend.Coupled with the lack of existing network address,routing table expansion problemand network performance issues,etc., for the future of more integrated businessnetwork research has become our urgent topic that needs to be performed.Based on the above background, thesis for a connection-oriented networkstructure of future network and future network transfer protocol FIP and three netsfusion is studied, and on this basis, mainly in the network routing in the futureallocation and selection are analyzed and designed. Paper’s work mainly includes thefollowing content: first to identify the user categories of routing networks for,business types of routing on this basis,and then according to user’s address for routingchannel choice. In system design, the cache manager respectively, packetformat(including FIP packet routing and forwarding packets) and routing aggregationwas studied. In FPGA design, respectively for multi-channel selector, packet filter,static random access memory SRAM, first-in, first-out buffer FIFO and forwardingengine five modules were designed. Design using VHDL hardware descriptionlanguage, and use the Quartus II and Modelsim software coding and functionsimulation of various modules. Tests have shown that theoretical research results isconsistent with the simulation results basically. Work of this paper for future routing switching technology research provides certain reference.
