RE: Sigtran [SUA] : Modification of Routing Key

Amrita,

This is a good question that we have thought about also.

In our SGP implementation, we are assuming that ASP1 and ASP2 are being controlled by a central application. Our
customers almost always implement multiple ASPs as multiple ethernet cards in a workstation.

So we're assuming that if ASP1 sends a modification request for RK1, then ASP2 knows about the modification as well. So
we will modify RK1 for both ASPs.

Subject: [Sigtran] Sigtran [SUA] : Modification of Routing Key

Hi,

Referring to section 4.4.1 of RFC 3868,]

An ASP MAY modify an existing Routing Key by including a Routing
Context parameter in the REG REQ. If the SGP determines that the
Routing Context applies to an existing Routing Key, the SG MAY adjust
the existing Routing Key to match the new information provided in the
Routing Key parameter.


IF two (example ASP1 and ASP2) or more ASPs have registered a Routing Key(RK1) and a request to modify the routing
key(RK1) from ASP1 modifies the key then in that case how do the other ASPs know of the change in Routing Key.
Should not the other ASP which had registered the same routing key be informed about the change. How do we do that?
