All things related to multicast

["Prashant Chopra" <>]

Colleagues,

Problem Statement 
We have 6 multicast streams running at 1.6 Mbps. Clients connected to the
leaf nodes are receiving really bad signal - very bad that there are more
lost packets than received packets. Unicast works okay - transport is TCP
not UDP. With Multicast, at a single hop from the server, clients receive
everything just fine - no packet loss. This indicates that server is sending
all the packets. But at the leaf nodes, things fall apart.
 
Question to Everybody
> Do any of you have any experience of best practices with ToS settings on
the streaming server (Microsoft) and/or QoS settings on the networking
side(Cisco)?

Our Troubleshooting Path
We are doing some troubleshooting by trying out RTSPU to find out if there
is a generic UDP issue instead of a Multicast UDP issue. This won't help
much in resolving the issue, but might help isolate the scope of the
problem.
