Re: [Tsvwg] SCTP applicability statement

Coene,

The applicability statement has the following text:

    3 Multihoming Issues

	...

	It should be noted that SCTP multihoming support only deals with
	communication between two endpoints of which one or both is assigned
	with multiple IP addresses on possibly multiple network interfaces.
	It does NOT deal with communication ends that contain multiple
	endpoints (i.e., clustered endpoints) that can switch over to an
	alternate endpoint in case of failure of the original endpoint.

As it is fundamental to the design of SIGTRAN UAs that such redundancy
between hosts be supported, this statement appears to indicate that
either SCTP is unsuitable for SIGTRAN UAs, or SIGTRAN UAs must include
their own support for handling clustered endpoints (e.g., UA queueing
and acknowledgements).

This is a significant issue with all the SS7 SIGTRAN UAs.  Is the
applicability statement saying that SIGTRAN must layer acknowledgements
over SCTP to accomplish this because no support is provided by SCTP?
