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 packet portion 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,wherein the packet portion test packet and the transport portion test packet are transmitted by a packet-transport gateway device in response to receiving a test packet from a transport segment routing (TSR) operations administration and management (OAM) controller.

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.

13. A method of detecting a fault in a transport segment in a packet-based network, the method comprising:
-
receiving a topology of the packet-based network including link characteristics and potential faults; transmitting a packet portion test packet over a packet portion of the transport segment based on the received topology; 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 based on the received topology; 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 whether there is a fault in the transport segment, wherein the packet portion test packet and the transport portion test packet are transmitted by a packet-transport gateway device in response to receiving a test packet from a transport segment routing (TSR) operations administration and management (OAM) controller. - View Dependent Claims (14, 15, 16)
