| 摘 要： | 为了满足光纤通道(Fibre Channel,FC)交换式网络不断增长的带宽需求,光纤通道协议提出了虚拟通道(Virtual Channel,VC)架构,通过逻辑上的通信通道对整网流量进行合理分配.本文将VC机制由"点到点"扩展为"端到端",并结合网络演算(Network Calculus)理论和信誉量漏桶机制,在强实时条件约束下,提出虚拟通道的分配策略,以减小整网业务流量的端到端延迟时间为优化目标,解决了VC架构的三项技术难题:每种VC数目的确定、每个VC的信誉量(Credit)如何保证、以及每条VC的路径选择.计算机仿真结果表明,随着网络负载强度的不断加大,扩展的VC分配策略具有适应能力,增强了在FC交换式网络中应用VC架构的有效性.

| Abstract: | To satisfy the increasing bandwidth requirement of Fibre Channel(FC) switched networks,Virtual Channel(VC) architecture was proposed in new version FC protocols,in order to allocate traffic flows by logical communications channels.Under hard real-time constraint,VC has been expanded from point-to-point to end-to-end,and this paper proposes the allocation scheme of VC based on Network Calculus and token bucket to reduce the end-to-end delay of traffic flows in whole FC networks.Thus it has been solved the th... |
