要約: In policy-based networks, two or more policies often have to cooperate because combined and customized network functions must be controlled using policies. Two types of policy trans-formation, policy fusion and policy division, are sometimes required to implement cooperating policy systems on high-performance hardware routers. Policy fusion transforms two or more policies into one, and policy division transforms a policy into two or more policies. These transformations causes a problem that the original policies must usually be strongly constrained to allow these transformations. This paper shows a method for resolving restrictions on the division of QoS policies by a software-hardware integration, i.e., by implementing virtual flow labels (flow IDs) in hardware and by dividing a policy and deploying the policies onto two filter blocks. We have developed a policy agent (PEP) and a gigabit router integrated by using this method. Both high-performance and flexibility are achieved by this integration.
