Abstract
In one embodiment, a particular service chain data packet is received by a particular service node, with the service chain data packet including a header identifying service chain information. The particular service node applies a service to the particular service chain data packet. The particular service node adds service-layer operations data to the particular service chain data packet, with the service-layer operations data related to the current service function or the particular service node. Subsequently, the particular service node sends the particular service chain data packet with the service-layer operations data from the particular service node. In one embodiment, networking operations data is also added to the particular service chain data packet. In one embodiment, an egress service node removes the service-layer (and possibly networking) operations data and forwards to another system, possibly after processing this operations data.
