Title: METHOD AND SYSTEM FOR PACKET PROCESSING OF A DISTRIBUTED VIRTUAL NETWORK FUNCTION (VNF)
Abstract:
Embodiments of the invention include methods of packet processing in a distributed virtual network function (VNF). In one embodiment, a packet processing rule is installed for a first processing unit based on a determination that a VNF is implemented over a plurality of processing units including the first processing unit and a second processing unit. The packet processing rule for the VNF prefers completing packet processing of a traffic flow in the first processing unit over forwarding the traffic flow to the second processing unit when the first processing unit is a designated processing unit for the traffic flow. A packet in the traffic flow is processed by the first processing unit based on the packet processing rule, and the packet is sent out of an egress point of the first processing unit for the VNF responsive to completion of the processing in the first processing unit.
