What is the need of routing context in M3UA

Going thought the RFC 3332 and have a doubt about RC, in M3UA we have a concept of routing context to identify an AS but same can be achieve by the routing Key (it seems) then what the purpose RC is serving.

The RK can be made up of a combination of fields, and would be expensive to parse with each message requiring it. The RC serves as a single value representing the RK - this single value is easier to parse and interpret under load.

You could think of this relationship in the way one often has an integer primary key in a database (equivalent to the RC) representing a compound unique business key (the RK).

RC is a numerical index that identifies a routing key. See RFC 4666/1.4.2.1 Page 14.

Can one implementation support single exchange and double exchange models of IPSP at the same time ? Or does it have to be configured and only one of the models can be active at a time ? Is there any M3UA procedure which can help in dynamic negotiation of SE/DE models.

Assume you have the conditions (one AS, etc.) to allow RC to be optional, does the RFC permit one side (IPSP SE mode for example) to still send an RC and the other to not include an RC? I think the answer is yes, but I can't find an explicit reference permitting it.

What is the reason behind not having the controlled re-routing in M3UA/SIGTRAN? Is it so that we don't need such procedures in IP world?

This is regarding M3UA SSNM messages.
1. Take an ASP with 2 SCTP link sets with each link set having 2 associations, connecting to two different SGs.

| - - - - -> Link Set 1 (2 Associations) - - - - -> SG 1 - - - - - >|ASP | | HLR-1| - - - - -> Link Set 2 (2 Associations) - - - - -> SG 2 - - - - - >|

If all connections between SG-1 and the HLR-1 break, the ASP would be notified with a DUNA.My question is through which SCTP connection between the ASP and SG-1, the DUNA would be sent in a proper SG implementation?Would it be sent to both connections or to a randomly selected one ?
