摘要： 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 (PLD) 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.

摘要翻译：确定在一个或多个网络中存在环回的方法包括存储与测试实例有关的信息; 从始发设备的端口发送包含与测试实例有关的信息的环回检测信标（LPDB）; 在预定时间段内监视端口以检测在预定时间段期间到达端口的LPDB; 以及确定检测到的LPDB是否包含与所存储的信息相对应的信息，以检测是否存在环回。该方法可以确定检测到的环回是端口环回，隧道环回还是服务环回。如果在预定时间段内没有检测到到达端口并且包含与存储的信息相对应的信息的LPDB，则可以删除与测试实例相关的存储的信息。
