- There are two solutions I can think of:
-
- a) give each IP stack a different IP address, and let ODI demultiplex
- on this
- b) get ODI to demultiplex on TCP/UDP port numbers, which would require it
- to manage (or have knowledge of) transport endpoint bindings.
-
- Clearly (b) is the best solution. A second-best would be to put a shim
- over ODI to do the demultiplexing function, but you still have to provide
- a way for each stack to tell it about bindings. Is there an API for this?
- How does PKTMUX work?
