BIERv6 Applications in IPTV and MVPN Services
Service Description
IP video traffic accounts for about 80% of traffic on an IP network. This is comprised of traffic for live TV (news, sports events, movies, TV series, and live webcasting), VOD, video surveillance, and other types of video broadcasts. Currently, IPTV services consist of mainly live TV and VOD services, lacking rich value-added IPTV applications. With the advent of the 5G and cloud era, there will be explosive growth in video transmission service applications such as 4K IPTV, 8K VR, smart city, smart home, autonomous driving, telemedicine, and safe city, especially in countries and regions with fast economic development.
MVPN over BIERv6 can be deployed on the public network to carry IPTV traffic. In addition to greatly reducing the network load and improving user experience (for example, delivering fast VOD, clear images, and smooth playback), BIERv6 multicast technology also simplifies deployment, O&M, and capacity expansion. This makes BIERv6 an ideal choice for large-scale deployment.
Network Description
In Figure 1, MVPN over BIERv6 is deployed on the carrier's IP backbone network, PIM or BIERv6 inter-AS static traversal is deployed on the IP metro network, and PIM is deployed in the VPN where the IPTV video source resides.
Feature Deployment
- In the control plane:
Deploy IS-ISv6 for BIERv6 to ensure connectivity at the underlay.
- Deploy MVPN so that MVPN A-D routes are used to establish BIERv6 PMSI tunnels and C-multicast routes are used to transmit PIM Join/Prune messages received from a VPN.
- Deploy PIM in the VPN to establish a VPN MDT.
- In the forwarding plane:
Deploy BIERv6 PMSI tunnels to efficiently forward multicast traffic.
