摘要：
In one embodiment, an apparatus in a network determines particular metadata to communicate infrastructure information associated with a particular packet to another apparatus in the network. The apparatus sends into the network the particular packet including a metadata channel, comprising said particular metadata, external to the payload of the particular packet. Examples of infrastructure metadata carried in a packet include, but are not limited to, information defining service chaining for processing of the packet, contextual information for processing of the packet, specific handling instructions of the packet, and operations, maintenance, administration (OAM) instrumentation of the packet.
