The Scalable Adaptive Multicast RG is working on hybrid application layer
multicast protocols. We would like to use P2PP as a substrate.
To support our experimentation without interfering with other implementations,
we propose that P2PP (or its future instantiation in Reload) provide an
experimental extension mechanism, such as:
1) a new message be added to the 18 existing message types:
P2PP-Msg = ... | Experimental
with some language that peers should quietly ignore experimental
messages that they don't recognize.
2) the experimental message
Experimental = Common-header
Peer-Info
Certificate-Sign-Request
Password
Extension-Name
Extension-Body
Extension-Name = SAM | ...
Extension-Body = extension-specific
The SAM overlay protocol is defined in
draft-buford-irtf-sam-overlay-protocol-00.txt
and defines the above extension mechanism.
