Policy provisioning performance evaluation using COPS-PR in a policy based network

This paper presents a study carried out to evaluate policy provisioning performance, by the COPS-PR protocol, in a policy based environment. First of all the prototypes developed are presented. These simulate the component behavior of the two lower layers of a policy based management system. Then the various measurements, done on the prototypes, are shown. All measures are carried out for several scenarios, described through the use of appropriate configuration policies, in an increasing complexity order. It is demonstrated that the architecture of COPS-PR is scalable, though the PDP can become a bottleneck.
