Hi to everybody, My name is Marco De Bernardi and I'm a student of Politecnico di Milano, I'm currently working on my master thesis at Cefriel ( a consortium between public and private - www.cefriel.it ) I regret in advanced for the length of the mail, I was not able to shorten it further. My thesis is focused on performance measurement of policy provisioning protocol (COPS-PR) in a policy based environment. As case study I chosen diff-serv configuration provisioning. This mail would be a public contribution to implementation problem we encountered and at the same time we want to know the mailing list opinion about the hypothesis of our implementation. I have implemented some PIB, PDP and PEP software prototypes, using C++ language on Linux OS. In the attached file there is the dettailed description of my work.
