【摘要】：隨著高性能網(wǎng)絡規(guī)模的增加,高階路由器結(jié)構(gòu)設計成為高性能計算研究的重點和熱點。使用高階路由器,網(wǎng)絡能實現(xiàn)更低的報文傳輸延遲、網(wǎng)絡功耗和網(wǎng)絡構(gòu)建成本,同時高階路由器的應用還可以提高網(wǎng)絡可靠性。高性能路由器的階數(shù)不斷提高,僅靠擴展單級crossbar交換結(jié)構(gòu)的階數(shù)使路由器內(nèi)部的連線資源急速增長,交叉開關的實現(xiàn)代價將不可接受,這就需要為高階路由器設計新型的交換結(jié)構(gòu)。近十年來,出現(xiàn)了以YARC為代表的經(jīng)典結(jié)構(gòu)化設計以及"network within a network"等新型設計方法,未來的研究重點是解決高階路由器結(jié)構(gòu)設計中遇到的緩存、仲裁和擴展性等各種問題。鑒于此,實現(xiàn)了一種多級無緩存高階路由器,這種高階路由器內(nèi)部是一個多級Clos網(wǎng)絡,每一級有相應的仲裁模塊對請求進行調(diào)度,數(shù)據(jù)包緩存在輸入/輸出端口實現(xiàn),除去這些緩沖區(qū)單元,該網(wǎng)絡是無緩存的。最后通過BookSim模擬器進行了大量的性能測試,所設計的路由器能夠正常工作,性能良好。
[Abstract]:With the increase of the scale of high performance network, the structure design of high-order router becomes the focus and hotspot of high-performance computing.Using high-order routers, the network can achieve lower packet transmission delay, network power consumption and network construction cost, and the application of high-order routers can also improve network reliability.The order of high performance router is increasing continuously. Only by extending the order of single-stage crossbar switch structure, the connection resource inside router increases rapidly, and the cost of implementing crossover switch will be unacceptable.This requires the design of a new switching architecture for higher-order routers.In recent ten years, classical structured design, represented by YARC, and new design methods such as "network within a network" have emerged. In the future, the focus of research is to solve the problems of cache, arbitration and expansibility encountered in the structural design of high-order routers.In view of this, a multi-level cache free high-order router is implemented. This kind of high-order router is a multi-level Clos network, each level has a corresponding arbitration module to schedule the request, and the data packet cache is implemented in the input / output port.Without these buffer units, the network is cache-free.Finally, a large number of performance tests are carried out through the BookSim simulator, and the designed router can work normally and has good performance.
