Abstract
A computer network having multiple, dissimilar network devices includes a system for implementing high-level, network policies. The high-level policies, which are generally device-independent, are translated by one or more policy servers into a set of rules that can be put into effect by specific network devices. Preferably, a network administrator selects an overall traffic template for a given domain and may assign various applications and/or users to the corresponding traffic types of the template. Location-specific policies may also be established by the network administrator. The policy server translates the high-level policies inherent in the selected traffic template and location-specific policies into a set of rules, which may include one or more access control lists, and may combine several related rules into a single transaction. Intermediate network devices, which may have one or more roles assigned to their interfaces, are configured to request traffic management information from the policy server which replies with a particular set of transactions and rules. The rules, which may correspond to the particular roles assigned to the interfaces, are then utilized by the int…
