摘要： According to one embodiment, a method may include instantiating a first maintenance end point on a first port of a first network element. The first maintenance end point may determine whether a heartbeat message has been received from a second maintenance end point instantiated on a second port of a second network element. In response to determining that the heartbeat message has been received, the maintenance end point may analyze the heartbeat message to determine an identifier for the second network element and an identifier for the second port. Based on the determination of the identifier of the second network element and the identifier of the second port, the network element may store information to an adjacency list, the information indicating at least one of an adjacency of the first port to the second port and an adjacency of the first network element to the second network element.

摘要： A method and system for performing synthetic loss measurements (SLM) includes methods for single-ended and dual-ended synthetic loss measurements. The methods include maintaining a session number indicative of a physical network component at each maintenance point used to perform synthetic loss measurements. The session numbers are maintained according to a novel protocol and are used to detect a change in the network component, such as resulting from a protection switch event. The session numbers enable the synthetic loss measurements to continue irrespective of changes in the values for the session numbers and to remove errors when computing frame loss that may arise when physical network components change. The disclosed methods and systems may be used when a link aggregation group exists between a local maintenance point and a remote maintenance point.
