TRANSPORT SEGMENT OAM ROUTING MECHANISMS
First Claim
1. A method of determining a property of a transport segment in a packet-based network, the method comprising:
- transmitting a test packet over a packet portion of the transport segment;
receiving packet portion results in response to the packet portion test packet;
transmitting a transport portion test packet over a transport portion of the transport segment;
receiving transport portion results in response to the transport portion test packet;
correlating the packet portion results and the transport portion results to generate correlated test results; and
processing the correlated test results to determine the property of the transport segment.

Abstract
Systems, methods, and devices for determining a property of, or isolating a fault in, a transport segment. A packet portion test packet can be transmitted over a packet portion of a transport segment. Packet portion results can be received in response to the packet portion test packet. A transport portion test packet can be transmitted over a transport portion of the transport segment. Transport portion results can be received in response to the transport portion test packet. The packet portion results and the transport portion results can be correlated to generate correlated test results. The correlated test results can be processed to determine the property of, or isolate the fault in, the transport segment.

21. A method for determining a failure in a segment-routing capable packet-based communications network, the method comprising:
-
detecting, by operations, administration, and maintenance (OAM) circuitry, whether a failure has occurred in the communications network; on a condition that the a failure in the communications network is detected by the OEM circuitry, determining, by the OEM circuitry, whether the failure is in a transport portion of the network or in a packet portion of the network.
