Signaling layer protocols specified within the Next Steps in
Signaling (NSIS) framework may rely on the General Internet Signaling
Transport (GIST) protocol to handle authorization.  Still, the
signaling layer protocol above GIST itself may require separate
authorization to be performed when a node receives a request for a
certain kind of service or resources.  This document presents a
generic model and object formats for session authorization within the
NSIS signaling layer protocols.  The goal of session authorization is
to allow the exchange of information between network elements in
order to authorize the use of resources for a service and to
coordinate actions between the signaling and transport planes.
This document defines an Experimental Protocol for the Internet
community.
