Abstract:
A method of determining the presence of a loopback in one or more networks comprises storing information related to a test instance; sending a loopback detection beacon (LPDB) containing information related to the test instance from a port on an originating device; monitoring the port for a predetermined time period to detect LPDBs arriving at the port during the predetermined time period; and determining whether a detected LPDB contains information corresponding to the stored information, to detect the presence of a loopback. The method may determine whether a detected loopback is a port loopback, a tunnel loopback or a service loopback. The stored information related to the test instance may be deleted if an LPDB arriving at the port and containing information corresponding to the stored information is not detected within the predetermined time period.

Claim (Index 47):
A system of determining the presence of a tunnel loopback a multi-section network at a port, the method comprising:\n a section level assigned to each section of said multi-section network; a unique domain number assigned to one or more domains wherein one domain comprises one or more sections at the same section level and zero or more section at a lower section level; a protocol data unit (PDU) stored on a memory at the port, wherein said PDU includes a Virtual Local Area Network (VLAN) signature; a loopback detection beacon (LPDB) containing said PDU, a domain number and a time stamp transmitted by said port into said network wherein said LPDB is restricted to one or more sections related to the domain number in the LPDB; wherein said port receives said LPDB and determines whether a received LPDB contains information corresponding to said stored PDU, to detect the presence of a loopback; and said port determines that said detected loopback is a tunnel loopback if said detected LPDB contains said VLAN signature and whether said detected loopback is a hard cable loopback or a remote facility loopback based on a difference between said time stamp and the arrival time of said detected LPDB.
