| 摘 要： | 现有的组播交换结构均是从单播交换结构发展而来，而目前的各种单播交换结构都存在各自的技术瓶颈，当被应用于组播交换时，既不能突破原交换结构的技术局限，又限制了组播交换的性能，因此现有的组播交换结构基本都不具备大规模可扩展的能力。本文提出基于分配格理论的线速组播交换结构，它不仅能满足大规模可扩展和线速组播要求，而且具有低时延、无抖动，不需要排队缓存等性能优势。本文分析并证明了该组播交换结构既能实现最优化的组播，又支持具有优先级的组播，从而在时延上保证了组播QoS(quality of service)。

| Abstract: | The traditional multicast switch fabrics(MSF) are mainly developed from the unicast switch fabrics(USF). Owing to the bottleneck of the current USF, almost all the existing MSF are not able to achieve high efficiency orexcellentlarge-scale scalability. Awire-speed MSF based on lattice theory is presented. It cannot only meet the requirements of superior scalability and wire-speed multicast, and has low delay, jitter free, and no queuing cache performance advantages. It is proved that the MSF can both achieve optimal multicast performance and support priority-based multicast which can guarantee the multicast QoS (quality of service) in delay. |
