Abstract
Presented herein are service-function chaining techniques. In one example, a service controller in a network comprising a plurality of service nodes receives one is configured to identify one or more service-functions hosted by each of the service nodes. The service controller defines a service-function chain in terms of service-functions to be applied to traffic in the network and provides information descriptive of the service-function chain to a classifier node.
