How about lots of GRE tunnels? :-)
I've done that with a few connections - mostly connecting to Cisco routers to pass multicast streams. I'm not sure how it would scale up in terms of the interface numbers and managing routes but it should work.
What was the network environment like that the tunnels went over?
Some over the internet, some private, but always with fixed src/dest addresses and nothing going over them that couldn't have run unencrypted over the internet.
RED (Random Early Discard) was specifically developed and deployed to break flows that lacked congestion control. CeeUceeME was the big culprit at the time. Multicast streams could have a lot of data lose if RED is needed to manage congestion.
Where would this happen - and would it happen to the encapsulating GRE packets or just bare udp multicast?
