Abstract
An example method for service node originated service chains in a network environment is provided and includes receiving a packet at a service node in a network environment that includes a plurality of service nodes and a central classifier, analyzing the packet for a service chain modification or a service chain initiation, classifying the packet at the service node to a new service chain based on the analysis, initiating the new service chain at the service node if the analysis indicates service chain initiation, and modifying an existing service chain for the packet to the new service chain if the analysis indicates service chain modification. In specific embodiments, the analysis includes applying classification logic specific to the service node. Some embodiments, service node attributes and order of service nodes in substantially all service chains configured in the network may be received from a central controller.
