IfNet Neutrality existed back then we would have had no chance to put together our multicast network unfortunately when Yahoo killed it, it stayed dead. To this day there is no multicast network that rivaled what we did in 1999 for content

GRE Tunnel -->
Tunnels:
Allow multicast content to pass over the
non native multicast Internet.
Peering:
MBGP/MSDP/PIM allow for efficient,
scaleable interdomain routing and
multicast content distribution.

• 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

4. 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.

• 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.
