Abstract

Multi Protocol Label Switching (MPLS) [1] has been widely deployed in both service provider and enterprise networks alike. The main drivers for deploying an MPLS based forwarding mechanism for IPv4 include Layer 2 [2] and Layer 3 [3] Virtual Private Networks, and Traffic Engineering [4] and Fast Reroute [5]. The protocol transparency of MPLS infrastructures can also be leveraged, with minimal core impact, to provide IPv6 services. MPLS 6PE (Provider Edge) [6] has proven to be a popular and widely deployed architecture for forwarding IPv6 unicast packets across an IPv4 / MPLS enabled core infrastructure. Along with unicast connectivity, today¿s networks are more and more often required to support IP multicast services as well. It is estimated that new types of end-user applications will significantly increase the need for deploying IPv4 and IPv6 multicast solutions. This paper discusses two possible architecture options for deploying IPv6 multicast [7] forwarding across an already existing IPv4 / MPLS enabled core infrastructure. In both of the scenarios, IPv6 unicast packets are transported through an MPLS 6PE solution.

IPv6组播在MPLS网络中的部署研究

MPLS (Multi Protocol Label Switching，多协议标签交换)[1]已经广泛应用于业务网络和企业网络中。部署基于MPLS的IPv4转发机制的主要驱动因素包括第2层[2]和第3层[3]虚拟专用网、流量工程[4]和快速路由[5]。还可以利用MPLS基础设施的协议透明性，以最小的核心影响提供IPv6服务。MPLS 6PE (Provider Edge)[6]已被证明是一种流行且广泛部署的架构，用于在启用IPv4 / MPLS的核心基础设施上转发IPv6单播数据包。随着单播连接，今天的网络越来越多地被要求支持IP多播服务。据估计，新型终端用户应用将显著增加部署IPv4和IPv6多播解决方案的需求。本文讨论了在已经存在的支持IPv4 / MPLS的核心基础设施上部署IPv6多播[7]转发的两种可能的架构选项。在这两种情况下，IPv6单播报文都是通过MPLS 6PE解决方案传输的。
