Co-operative load sharing and redundancy in distributed service chains in a network environment

Abstract

An example method for co-operative load sharing and redundancy in distributed service chains is provided and includes deriving a service chain comprising a plurality of services in a distributed virtual switch (DVS) network environment, where a first service node provides a first portion of a specific service in the plurality of services to a packet traversing the network, and a second service node provides a second portion of the specific service to the packet, and configuring service forwarding tables at virtual Ethernet Modules associated with respective service nodes in the service chain. In a specific embodiment, the first service node and the second service node provide substantially identical service functions to the packet, wherein the specific service comprises the service functions. In various embodiments, each service node tags each packet to indicate a service completion history of service functions performed on the packet at the service node.
