Abstract
A network includes an egress node connected to an ingress node via a network path. The egress node is configured to receive, from the ingress node, a group of packets via the network path, where each packet includes an operations, administration, and management (OAM) field appended to the packet, and where the OAM field stores OAM information. The egress node is further configured to read the OAM information from the packets; analyze the OAM information, associated with one or more of the packets, to determine that a network condition exists on the network path; and notify the ingress node that the network condition exists to permit the ingress node to perform a rerouting operation.
