Abstract
A system and method for providing services to packet flows in a communication network. The services include enhanced charging, stateful firewalls, traffic performance optimization (TPO) and advanced services such as content differentiated charging, per-subscriber stateful firewalls, and VPNs, for example. A gateway can be used to route each packet flow through the services on a per-subscriber basis by inspecting accounting messages and checking subscriber profiles prior to setting up a new packet flow session. By directing the packet flow through the services requested latency can be reduced as well as the need to have equipment for each session regardless of whether the service is provided to the packet flow. The services can be provided in-line as well.
