Abstract
Methods and systems for providing IP services in an integrated fashion are provided. According to one embodiment, packets are load balanced among virtual routing processing resources of an IP service generator of a virtual router (VR) based switch. A packet flow cache is maintained with packet flow entries containing information indicative of packet processing actions for established packet flows. Deep packet classification is performed to determine whether a packet is associated with an established packet flow. If so, the packet is directed to one of multiple virtual services processing resources representing application-tailored engines configured to provide managed firewall services. If the packet is allowed, it is returned to the source virtual routing processing resource for forwarding.
