Estimating the term…
A system within a computer network identifies specific traffic flows originating from a given network entity and requests and applies appropriate policy rules or service treatments to the traffic flows. A network entity includes a flow declaration component that communicates with one or more application programs executing on the entity. The flow declaration component includes a message generator and an associated memory for storing one or more traffic flow data structures. For a given traffic flow, the application program issues one or more calls to the flow declaration component providing it with information identifying the traffic flows. The flow declaration component then opens a flow management session with a local policy enforcer that obtains policy rules or service treatments for the identified flow from a policy server and applies those rules or treatments to the specific traffic flows from the network entity.
A method for applying a service treatment to a plurality of network messages issued by a network entity connected to a computer network, the network messages corresponding to a traffic flow, the computer network configured to support transport and network communication layers and having a policy enforcer, the method comprising the steps of:
A computer readable medium containing executable program instructions for use in applying a service treatment to a plurality of network messages issued by a network entity connected to a computer network, the network messages corresponding to a traffic flow, the computer network configured to support transport and network communication layers and having a policy server, the executable program instructions comprising program instructions for:
A policy server for use in applying a service treatment to a plurality of network messages issued by a network entity connected to a computer network, the network messages corresponding to a traffic flow, the computer network configured to support transport and network communication layers and having a policy enforcer, the policy server comprising:
A policy enforcer for use in applying a service treatment to a plurality of network messages issued by an application program running on a network entity connected to a computer network, the network messages corresponding to a traffic flow, the computer network configured to support transport and network communication layers and having a policy server, the policy enforcer comprising:
