Abstract
An example method for network address translation (NAT) offload to network infrastructure for service chains in a network environment is provided and includes receiving a packet at a network infrastructure in a network comprising a plurality of service nodes interconnected through the network infrastructure, each service node executing at least one service function, identifying the packet as belonging to a first flow based on a cookie in a network service header of the packet that indicates a service chain that includes a sequence of service functions to be executed on the packet at the service nodes, determining that a service function in the service chain is to be offloaded from one of the service nodes to the network infrastructure for subsequent packets of the first flow, and executing the offloaded service function at the network infrastructure for subsequent packets of the first flow.
