ason-req and call segments

[Dimitri.Papadimitriou@alcatel.be]

folks, during the ccamp wg meeting discussions on ason-req,
a remark has been made asking for clarifications on "call
segments", this is the proposed text:

"4.3 Support for Call Segments

   As described in [ITU-T G.8080], call segmentation may be applied
   when a call crosses several administrative domains. As such, an end-
   to-end call may consist of multiple call segments, when the call
   traverses multiple administrative domains. For a given end-to-end
   call, each call segment can have one or more associated connections
   and the number of connections associated with each call segment may
   be different.

   The initiating caller interacts with the called party by means of
   one or more intermediate call controllers located at administrative
   domain boundaries (i.e., inter-domain reference points) and at the
   user-network reference points. Call segment capabilities are defined
   by the policies associated at these reference points.

   This capability allows for independent (policy based) choices of
   signaling, concatenation, data plane protection and control plane
   driven recovery paradigms in different administrative domains."

hope it addresses everyone concerns;
thanks,
