RSVP policy control using XACML

This work proposes a XML-based framework for distributing and enforcing RSVP access control policies, for RSVP-aware application servers. Policies are represented by extending XACML, the general purpose access control language proposed by OASIS. Because RSVP is a specific application domain, it is not directly supported by the XACML standard. Hence, this work defines the XACML extensions required for representing and transporting the RSVP access control policy information. The XACML-based framework is proposed as an alternative to the IETF PCIM-based approach. Both approaches are compared in this paper.
