DENOG3 - Building MPLS based Multicast VPN Solutions
Channel: DENOG
Date: 2020-11-10

There is increasing demand for Multicast functionality, especially in the context of IPTV wholesale and real-time information feeds.

Service providers today use Multiprotocol Label Switching (MPLS) to offer a variety of services on top of a common core network infrastructure. Unfortunately, MPLS was originally designed for unicast IP traffic.

This presentation illustrates how BGP/MPLS based layer-3 VPNs can be extended to support multicast traffic with new concepts recently standardized. Multicast VPN makes use of the concept of point-to-multipoint LSPs to handle multicast traffic in a way such that bandwidth efficiency and scalability is achieved at the same time. The different mechanisms that need to work together to build this solution are discussed.
