Abstract
A network gateway device includes an ingress interface, an egress interface, and a load balancing module coupled to the ingress and egress interfaces. The load balancing module configured to receive a packet from the ingress interface, determine a set of a plurality of processes corresponding to a connections session associated with the packet based on a policy. For each of the identified processes, the load balancing module is to identify a service processing module executed by a virtual machine that is capable of handling the identified process, and to send the packet to the identified service processing module to perform the identified process on the packet. The packet is then transmitted to the egress interface of the gateway device to be forwarded to a destination.
