Summary


Multicast integration into MPLS is driven by enterprise applications such as videostreaming, IPTV, and so on and are deployed as VPNs, thus creating MVPNs. We have discussed how an existing MPLS infrastructure can implement MVPNs and have identified the IETF draft (draft-rosen-vpn-mcast), upon which the majority of industry implementations is based. Current IETF-related work involves exploring multicast and traffic engineering constructs to efficiently constrain the multicast flows, in addition to developing a lightweight connectivity check for management purposes. Finally, service providers are using this technology to offer managed services for enterprise multicast applications.
