All things related to multicast

[Greg Shepherd <>]

Okay, I put up another mcast VOD demo for those interested. I've tweaked
the DF params to get the content source through a T1, though the receiver
BW reqs are much lower. Here are the current settings:

Streaming delivery:
    Content streaming rate:   300 Kbps
    Client reception rate:   600 Kbps
    Startup time:   9 seconds
    Loss tolerance:   15 percent
    Scheme:   Minimizing meta content bandwidth
    Multicast groups used:   233.15.108.46 (14 groups)
    Meta-Content bandwidth:   1138 Kbps
    Minimum client storage:   1.88 MB

You can get the client and the link to the content from:
