Re: [Dime] RFC 3588 (Diameter Base Protocol)

Hi,

I see. Then I would propose that in the current state of this spec, we can
simply state a minimum (as stefan has mentioned) that a peer MUST be ready
to handle un-ordered messages. Then someone can volunteer a more proper
guideline for SCTP stream usage/assignment either in an errata or an another
draft.

regards,
victor
