ABSTRACT:
Methods and systems for providing IP services in an integrated fashion are provided. According to one embodiment, a system includes a switch fabric and a line interface
etwork module, multiple virtual routing engines (VREs) and a virtual services engine (VSE) coupled with the switch fabric. The line interface
etwork module receives packets, steers ingress packets to a selected VRE and transmits egress packets according to their relative priority. VREs determines if a packet associated with a packet flow requires processing by the VSE by performing flow-based packet classification on the packet and evaluating forwarding state information associated with previously stored flow learning results. The VSE includes a central processing unit configured to perform firewall processing, Uniform Resource Locator (URL) filtering and anti-virus processing. If the packet is determined to require processing by the VSE, then the packet is steered to the VSE for firewall, URL filtering and/or anti-virus processing.
