组播路由器传统存储方式存在存储空间的严重浪费,内部高速交换网络在转发数据包时存在数据包严重冗余。针对传统方法中存在的问题,提出了优化存储转发模型。该优化模型通过存储优化降低存储空间的消耗;通过重构组播路由转发项与转发策略以减少数据包内部交换的次数。实验分析与比较证明了其具有较好的存储性能与转发性能,减轻了内部交换网络的负担,减少了组播数据包转发时延,显著提升了路由器的有效性。
組播路由器傳統存儲方式存在存儲空間的嚴重浪費,內部高速交換網絡在轉髮數據包時存在數據包嚴重冗餘。針對傳統方法中存在的問題,提齣瞭優化存儲轉髮模型。該優化模型通過存儲優化降低存儲空間的消耗;通過重構組播路由轉髮項與轉髮策略以減少數據包內部交換的次數。實驗分析與比較證明瞭其具有較好的存儲性能與轉髮性能,減輕瞭內部交換網絡的負擔,減少瞭組播數據包轉髮時延,顯著提升瞭路由器的有效性。

Traditional storage pattern of multicast router has severe waste in storage space, and the internal high-speed switched networks ( IHSN) has serious datagram redundancy when forwarding them.Therefore, we put forward the optimised multicast storage and forwarding ( OMSF) model to handle the deficiencies in traditional method.The OMSF model lowers the consumption of storage space via storage optimisation, and the frequency of datagram switched in IHSN is decreased by reconstructing the forwarding item and the forwarding policy of multicast routing.It is proved by the experimental analysis and comparison that this model has good storage and forwarding performances, lightens the load of IHSN and shortens the forwarding delay of multicast datagram as well, it also significantly improves the effectiveness of router.
