为了解决IPv4(因特网协议版本4)公网地址严重不足与IPTV(网络电视)业务之间的矛盾,通过IPv6组播承载IPTV直播业务,在城域骨干网开启IPv6PIM-SM(协议无关组播-稀疏模式),选择BSR(自举路由器)方式进行RP(汇集点)部署,待设备支持后逐步过渡至anycastRP方式;在城域接入网分别对IPoE(以太网上的互联网协议)和PPPoE(以太网上点到点协议)接入两类场景进行了测试,PPPoE接入适用于快速过渡至IPv6承载IPTV业务,IPoE将是最合适IPv6承载IPTV业务的接入方式。
In order to solve the conflict between IPv4 (Internet Protocol Version 4) public network address and IPTV (Internet Protocol Television) service, the IPTV live service is carried through IPv6 multicast and the IPv6 PIM-SM (Protocol Independent Multicast - Sparse mode), select the BSR (bootstrap router) RP (aggregation point) deployment, to be supported by the equipment after the gradual transition to anycastRP way; in the metropolitan access network IPoE (Ethernet over Internet Protocol) and PPPoE Online point-to-point protocol) to access two types of scenarios. PPPoE access is suitable for fast transition to IPv6 for carrying IPTV services. IPoE will be the most suitable access way for IPv6 to carry IPTV services.
