Policy server. A and policy server B can each manage its own set of devices, such as switches and routers, but can still exchange policy information between themselves. This scheme can be helpful when devices from dif- ferent vendors are being managed, thereby helping to - overcome the lack of interoperability that can prove problematic in policy-based management implementation.
