摘要： Methods and systems are provided for managing an Ethernet ring protection switching (ERPS) protocol in an Ethernet network. The method includes receiving an administrative data packet at a first network element; determining whether the administrative data packet contains an ERPS membership setting from a second network element; when the administrative data packet contains the ERPS membership setting from the second network element, comparing an ERPS membership setting at the first network element to the ERPS membership setting from the second network element; and performing an action when the ERPS membership setting at the first network element is different than the ERPS membership setting from the second network element.

摘要： A method and system for identifying the absence and presence of a ring protection link in Ethernet networks are disclosed. The method may include sending, by a node in a ring of an Ethernet network having a plurality of nodes and an RPL, an APS message. The method may further include receiving, by the node via the ring, the APS message and determining whether the node is an RPL owner node that controls the flow of traffic on the RPL. The method may further include, raising, when it is determined that the node is not an RPL owner node, an alarm indicating that the ring lacks a provisioned RPL owner node.

摘要： Partial updates to an improved DDS are enabled by a framework API that enables different threads to asynchronously access a topic, while maintaining integrity of the topic in the improved DDS. New fields in a topic of the improved DDS may be added by new DDS publishers for the topic without altering the functionality of existing DDS publishers for the topic.

摘要： In accordance with embodiments of the present disclosure, a method is provided for communicating multicast traffic. The method may include in response to receipt of multicast control traffic at a network element to be communicated to a protection switching group, communicating the multicast control traffic to each of a working path and a protection path of the protection switching group. The method may also include in response to receipt of multicast control traffic via either of the working path and the protection path, processing the multicast control traffic as if the multicast control traffic was received via both the working path and the protection path.
摘要翻译： 根据本公开的实施例，提供了一种用于传送多播业务的方法。 该方法可以响应于在要传送到保护交换组的网络单元处的接收到组播控制业务，将组播控制业务传送到保护交换组的工作路径和保护路径中的每一个。 该方法还可以包括响应于通过工作路径和保护路径之一接收到组播控制业务，如同通过工作路径和保护路径接收到组播控制业务一样处理组播控制业务。
