Peering: MBGP/MSDP/PIM allow for efficient, scaleable interdomain routing and multicast content distribution.

broadcast.com multicast • Pitfalls –
Lack of support by equipment vendors. Large scale multicast requires interoperation and standardization – QOS. Larger scale deployment is coming. – Application limits in scaleable multicast and management

broadcast.com multicast Why we do
like we do: MBGP with MSDP and PIM are much more scaleable than the protocols of old. They offer more efficient routing between larger networks. Peering with smaller ISP’s does not have the demand of the lager networks. Networks are smaller and content distribution is more easily controlled. Tunnels work, but direct peering is obviously a better choice. The Internet is not perfect and as QOS becomes more prevalent it will become a necessity.

broadcast.com multicast • What's next
in 1999? – Lager Scale enterprise deployment of multicast – QOS improvements in both management and application. – A faster last mile. Creating more demand for high quality broadband content. – More standards based tools and protocols allowing for true interoperability.
