Re: SCTP Association and M3UA relation

I dont think this is the limitation, though having multiple associations
between the same nodes is of little help. If you want path redundancy, then
a single association can very well do that.
If a node is designed that way, I dont see a problem with having multiple
associations between two nodes. As the associations are mapped to the same
node pair, management messaging should not be considered association
specific. Consider it one ASP-SGP pair specific and then all rules about
duplicate messaging apply.
This has to be implementaion specific.
