基于公平服务多维加权轮询调度的IPTV组播流量控制策略

根据大规模接入汇聚路由器（ACR)的总体技术规范，IPTV组播复制在ACR的以太网分合路器（EMD)中进行，而IPTV组播业务的增长会对其他业务造成冲击，因此需要对IPTV组播流量进行控制，以保证其他业务的带宽分配，针对IPTV流量控制中的关键环节──队列调度，提出了一种公平服务多维轮询调度策略(FSMWRR)，性能仿真的结果表明该调度策略能够满足IPTV业务的低时延、时延抖动的需求，同时保证各个业务带宽分配的公平性。

Scheduling scheme of IPTV multicast traffic control based on fair service and multidimensional weighted round robin

According to the general technology criterion of Access Convergence Router (ACR), the IPTV multicast copy is processed in Ethernet Multiplexer-Demultiplexer (EMD). Because the increase of the IPTV multicast service will impact other service, the IPTV multicast traffic should be controlled to ensure the bandwidth allocation of other service. To solve the key portion - the queue schedule of IPTV multicast traffic, a scheme of Fair Service and Multidimensional Round Robin was presented, the result of simulation indicate that Fair Service and Multidimensional Weighted Round Robin (FSMWRR) can achieve the good delay and jitter performance for IPTV service and provide fair bandwidth allocation for all service.
