Abstract
A method of supporting service chaining at a network device of a data network is disclosed. The data network offers a set of services associated with a set of network devices, where subscribers of the data network are served by chains of one or more services. The method starts upon receiving a frame, and the network device selects a chain of one or more services for the frame to be processed by the data network. The network device encapsulates the frame with a reflected frame message (RFM) header, the RFM header containing source information associated with the network device, destination information associated with an immediate next service for the frame to be processed, an operation code indicating the frame being an RFM frame. Then the network device sends the encapsulated frame out of the network device according to the destination information of the encapsulated frame.
