摘要： A mirror maintenance endpoint (MEP) is hosted on a provider edge switch within an Ethernet network to perform service level mirroring to a network management device of the Ethernet network. The mirror MEP is configured by the network management device to receive all mirrored frames from provider edge switches in a service provider network and to switch the mirrored frames to the network management device. The mirrored frames are mirrored by the provider edge switches to the mirror MEP during mirror sessions initiated by the network management device.

摘要： A network element in an Ethernet OAM network is operable to detect congestion associated with an OAM domain and generate a congestion notification to MEPs in the OAM domain using a modified Ethernet OAM protocol. When a network element detects congestion in one or more queues associated with an MEP in an OAM domain, it triggers a congestion state. The MEP transmits a congestion notification to other MEPs in the OAM domain. The notifying MEP, as well as other MEPs receiving the congestion notification, initiate a network management protocol message to a network management system for the OAM domain. The MEPs in the OAM domain may also propagate the congestion notification to MEPs in higher maintenance level OAM domains.
摘要翻译：以太网OAM网络中的网元可用于检测与OAM域相关联的拥塞，并使用修改的以太网OAM协议向OAM域中的MEP生成拥塞通知。当网络元素检测到与OAM域中的MEP相关联的一个或多个队列中的拥塞时，它触发拥塞状态。 MEP向OAM域中的其他MEP发送拥塞通知。通知MEP以及接收到拥塞通知的其他MEP向OAM域的网络管理系统发起网络管理协议消息。 OAM域中的MEP也可能在更高维护级别的OAM域中将拥塞通知传播到MEP。

摘要： A method for assigning a priority level to a stream by a network element in a communications network, where the network element has a plurality of communications ports is disclosed. The method includes monitoring at least one of the ports for at least one stream being communicated between a first user agent and a second user agent during a Session Initiation Protocol (SIP) communication session. The SIP communication session includes a plurality of SIP packets. The network element captures at least one SIP packet of the plurality of SIP packets and extracts information from the at least one captured SIP packet to determine a service type of the at least one stream. The network element assigns a priority level to the at least one stream based on the service type and according to a policy that defines priority levels for streams according to a plurality of service types.
