WDM网状网中动态多播流量疏导的结构与算法

Architectures & algorithms of dynamic multicast traffic grooming in WDM mesh networks

回顾了近期WDM网状网中动态多播流量疏导问题的研究成果。讨论和比较了文献中动态多播会话的动态路由和会话供应的技术,还提出了几个关于此问题的未来研究方向。

Many new applications in high-performance networks are of the multicast traffic type. Since most of these applications require subwavelength bandwidth, some streams are usually groomed onto the same wavelength.Generally multicast sessions now tend to exhibit a dynamic nature.Recent research works on dynamic multicast traffic grooming in WDM mesh networks are reviewed. Techniques for dynamic routing and session provisioning of multicast sessions are compared and discussed.Some future research directions of this issue are also presented.
