Abstract
A method of establishing a service operations administration and maintenance (OAM) session between an originator and a reflector in a communication network includes continuously monitoring, by the reflector, any test packets transmitted by the originator. The originator transmits to the reflector, at a time indicated by a first timestamp, a test packet. The reflector receives the test packet at a time indicated by a second timestamp and generates a unique flow identifier that identifies the reflector. The reflector transmits the test packet to the originator. The reflector assigns a sequence number to the test packet. The originator receives the test packet at a time indicated by a fourth timestamp. The reflector stores the unique flow identifier at least for the duration of the OAM session.
Claims14
A method of establishing a service operations administration and maintenance (OAM) session between an originator and a reflector in a communication network, comprising:
- continuously monitoring, by the reflector, any test packets transmitted by the originator;
- transmitting at a time indicated by a first timestamp, by the originator to the reflector, a test packet;
- receiving at a time indicated by a second timestamp, by the reflector, the test packet;
- generating, by the reflector, a unique flow identifier which identifies the reflector;
- assigning, by the reflector, a sequence number to the test packet transmitted by the reflector;
- transmitting at a time indicated by a third timestamp, by the reflector, the test packet back to the originator;
- and
- receiving at a time indicated by a fourth timestamp, by the originator, the test packet,
- wherein the reflector stores the unique flow identifier at least for the duration of the OAM session.
A method of establishing a service operations administration and maintenance (OAM) session between an originator and a reflector in a communication network, comprising:
- continuously monitoring, by the reflector, any test protocol data units transmitted by the originator;
- receiving a test protocol data unit by the reflector;
- generating, by the reflector, a unique flow identifier which identifies the reflector;
- relaying the test protocol data unit to the originator by the reflector;
- and
- assigning, by the reflector, a sequence number to the test protocol data unit relayed by the reflector,
- wherein the reflector stores the unique flow identifier at least for the duration of the OAM session.
A system for establishing a service operations administration and maintenance (OAM) session between an originator and a reflector in a communication network, comprising:
- an originator configured to generate a test protocol data unit and to transmit the test protocol data unit along a test path to a reflector;
- and
- the reflector configured to receive the test protocol data unit from the originator and to relay the test protocol data unit to the originator, the reflector being further configured to generate a unique flow identifier identifying the reflector and to store the unique flow identifier at least for the duration of the OAM session, the reflector being further configured to assign a sequence number to the test protocol data unit transmitted by the reflector,
- wherein the originator is configured to receive the test protocol data unit from the reflector.
