Abstract

In one embodiment, an apparatus can include a service broker configured to: (i) register a service classifier, and to provide context information to the service classifier; and (ii) register a plurality of service nodes. The service broker can also receive capability and service requests from the service classifier. Further, the context information can include a service header, a reachability indication, and an encapsulation, where the service header and the encapsulation may be attached or related to a packet in the service classifier. In addition, the service classifier can use this information to redirect the packet to a first service node.
