Abstract
A computer-implemented method tracks congestion in a service function chain. The method includes receiving a packet at a service function forwarding node of the service function chain, the packet having an information packet, a transport header, and a network service header, forwarding the packet to a service function in accordance with the network service header, detecting congestion, and updating a congestion field in the network service header to indicate congestion was encountered in the service function chain.
