Policy based management is being adopted widely for different domains like QoS, security and VPNs in order to allow newservices and facilitate network management. Also, the interface to the network device and the information models required forspecifying policies are either standardized or being standardized in IETF and DMTF. This paper reports the design,implementation, and performance evaluation of a policy based QoS management system for the IntServ/DiffServ basedinternet which is based on COPS for interfacing with the network device and on LDAP for interfacing with a directory for storingpolicies. The design is based on distributed components and CORBA is used as a middleware for component interaction.The Diffserv policies are installed based on role combination assigned to the network device interfaces and policy caching isused to improve the performance. The feasibility and performance of managing and deploying IntServ and Diffserv policies forQoS management is demonstrated using Linux-based routers. The preliminary performance measurements show that thepolicy server response time is below 5ms per request for 20 COPS-RSVP requests per second. COPS-PR processing takesmore time compared to COPS-RSVP requests. It is found that the directory access could become a bottleneck in scaling theperformance of the policy server and it can be improved substantially by employing appropriate policy caching mechanisms.
