提出了一个在BGP/MPLS VPN环境下支持QoS的组播方案。在BGP/MPLS VPN域的边缘路由器节点上通过构造DiffServ模型,实现对组播QoS的支持;在BGP/MPLS VPN域中,用改进的基于边缘路由器簇树算法构造组播默认分发树,来降低其总体路径费用。
Proposed a multicast solution that supports QoS in BGP / MPLS VPN environment. In the BGP / MPLS VPN domain edge router node by constructing a DiffServ model to achieve the multicast QoS support; BGP / MPLS VPN domain, with an improved edge router tree-based clustering algorithm to construct a multicast default distribution tree to reduce The overall path costs.
