Abstract
A method for routing packets in a router includes establishing a flow data structure identifying a packet flow through a virtual router in the router. Next, a system executing the method receives a packet, said packet having at least one packet header. The method then compares a subset of the at least one packet header to a subset of the flow data structure. If the subset of the at least one packet header matches the subset of the flow data structure, then the packet can be hardware accelerated to a network interface. Otherwise, the packet can be either dropped, or forwarded to a general purpose processor for processing.
