Abstract:
A method for augmenting metadata of a network service header is disclosed. The method includes receiving, at a first service node, a packet or frame of a traffic flow, wherein the packet has a payload and the network service header including a first metadata and a first service path information for the traffic flow, classifying, by the first service node, at least one of the payload and the first metadata to generate a second metadata different from the first metadata, and augmenting, by the first service node, the first metadata using the second metadata before forwarding the packet or frame to a second service node.
