SCTP multihoming issues draft
Previous week, the draft on SCTP multihoming issues was published.
Apart from some editorial changes concerning author list and missing/wrong
the only major change is a sentence added at the end of paragraph 2.3 SCTP
multihoming and Network Adress Translators(NAT):
"It should be noted that the NAT box becomes a single
point-of-failure in this case, as ALL the paths of the SCTP
association have to go through that single NAT box."
Theoretical it is possible to let all the different paths run through
different NAT boxes, but then the NAT boxes would never know exactly when to
teardown/terminate the association as the terminate or abort takes only one
of the paths(and there are other difficulties, such as the heartbeats
...etc...) So in practical terms this sentence should be correct. If you
feel otherwise, please let me know and I'll remove or add something to it to
make everything clear.
The draft can be found at the IETF draft directory:
Multihoming issues in the Stream Control Transmission Protocol
If by then end of next week, no further issues have been identified, then I
would ask for this draft to be moved to informational.
