All things related to multicast

[Dan Pritts <>]

One other thing, make sure you rate-limit your iperfs to some reasonable value when you are sending it out over a WAN.

what is "reasonable" depends on your connectivity at U. Houston.  I'm sure the default 1Mb/sec would be OK but I wouldn't send out 100Mb/sec without asking first.

Huy,

It's really no different assuming you've already got interdomain multicast routing working. Just make sure you are using a large enough TTL. Some of the tools set it to 1. Also, see multicast.internet2.edu(I think that's the right place) for past hands-on workshop materials which include a number of interdomain test scenarios.

I'm trying to setup a mcast experiment where I can use iperf to send mcast UDP packets from 1 node and observe

the packet loss ratio on another node over Internet2.

I was able to setup a similar experiment over different VLANs using network infastructure at University of Houston.

Now I'm extending the problem size and trying to setup the experiment on Internet2 to study the packet loss ratio.

I'm new to internet2 so I want to know if there are tutorials that help me with the experiment setup?

I just do'nt really know where to start

Any advice would be appreciated

Thank you
