Towards Extensible Policy Enforcement Points [chapter]

Raouf Boutaba, Andreas Polyrakis
2001 Lecture Notes in Computer Science  
COPS and its extension for policy provisioning, COPS-PR, are currently being developed by IETF to implement PBN. In COPS-PR, the PDP installs to the PEP policies that the latter should enforce.  ...  Policy-Based Networking (PBN) seems to be a promising alternative for Configuration Management, and has already received significant attention.  ...  Notice, also, that the exchange of information is performed in a provisioning mode, similar to COPS-PR. We are examining whether an extension of COPS-PR would be suitable for such exchange of data.  ...

Evaluation of policy-based admission control mechanisms in NGN

Pedro Goncalves, Ricardo Azevedo, Diogo Gomes, Jose Luis Oliveira, Rui L. Aguiar
