摘要： A method may include receiving, at a network interface of a first network element, an Internet Group Management Protocol (IGMP) message from a second network element. The method may also include updating first multicast group data associated with the network interface based on the received IGMP message, the first multicast group data including one or more entries setting forth a multicast group and one or more other network elements which are members of the multicast group. The method may additionally include determining whether the second network element is the sole member of its multicast group based on the IGMP message and the first multicast group data. The method may further include forwarding the IGMP message to a switching element of the first network element in response to determining that the second network element is the sole member of its multicast group, the switching element communicatively coupled to the network interface.

摘要： A computational method and system for estimating port delays in a network may use a data-driven estimation with quadratic programming based on available network path data that is already collected. In this manner, port delays for each individual port in the network may be estimated without having to measure each individual port using sensors.

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.

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.
