Hi Magnus ,Stephan,
The draft of draft-wenger-avt-topologies discusses multi-endpoint topologies commonly used in RTP based environments. But i think there are some topologies missing. For example , in peer-to-peer style IPTV,the following topologies are necessary.
+---+ +---+ +---+
| A |<------->| B |<------->| C |
+---+ +---+ +---+
Figure 1 point to point
The main property of this topology is that A sends to B,Meanwhile ,B sends to C.
+---+ +---+ +---+
| A | | B | | C |
+---+ \ +---+ /+---+
\ | /
\ | /
\ | /
\ | /
+---+
| D |
+---+
Figure 2 Multipoint to point
The main property of this topology is that multipoint senders(A,B,C) send to D.
The above are common scenarios in P2P-based streaming media.
Thanks.
Donghui Wang.
