Re: Use of SAP in a PIM SSM Network

[Supratik Bhattacharyya <Supratik@sprintlabs.com>]

As an example of a web-based interface for SSM-cast, you can look at the UofO
SSM Trial page :

http://videolab.uoregon.edu/projects.html

Note that this is currently set up to use URD on the receiving host's DR, but this
is not
a fundamental restriction, and can be easily changed to support a v3 host running
v3-enabled
apps (with a v3 DR of course)...

Cheers,
