Abstract
Packets are encapsulated and sent from a service node (e.g., packet switching device) using one or more services applied to a packet by an application node (e.g., a packet switching device and/or computing platform such as a Cisco ASR 1000) to generate a result, which is used by the service node to process packets of a flow of packets to which the packet belonged. An example of a service applied to a packet is a classification service, such as, but not limited to, using deep packet inspection on the packet to identify a classification result. The service node can, for example, use this classification result to process other packets in a same packet flow, such that all packets of a flow do not need to be, nor typically are, sent to an application node for processing.
