摘要： A Maintenance Association and corresponding method for configuring maintenance entities for Ethernet Tree (E-Tree) type service instances. A root MEP communicates with each of a plurality of leaf MEPs. Remote MEP state machine instances are activated within the root MEP for each of the plurality of leaf MEPs. Within each leaf MEP, however, only the remote MEP state machine instance for the root MEP is activated while leaving the remote MEP state machine instances for all other leaf MEPs in an inactive state in which Connectivity Check Messages (CCMs) are not exchanged.

摘要： A method in a Maintenance Association Endpoint, MEP, for controlling traffic between a first network element and a second network element connected by a working Traffic Engineering Service Instance, TESI, and a protection TESI. The first network element sets a Traffic field in a Connectivity Check Message, CCM, sent to the second network element. The Traffic field may be set by utilizing a reserved bit within a Flags field of the CCM. The Traffic field indicates which TESI is being utilized to transport the traffic. The second network element takes action to control the traffic based upon a value of the Traffic field in the received CCM. When the Traffic field value in the received CCM does not match the Traffic field value in CCMs sent from the second network element for a predefined period of time, the second network element moves the traffic from its current TESI to the other TESI.
摘要翻译：维护关联端点（MEP）中的方法，用于控制由工作的流量工程服务实例，TESI和保护TESI连接的第一网络元件和第二网络元件之间的流量。第一个网元在连接检查消息（CCM）中设置一个发送到第二个网络元件的流量字段。可以通过利用CCM的Flags字段内的保留位来设置Traffic字段。流量字段指示哪个TESI正在用于传输流量。第二网络单元根据接收的CCM中的业务字段的值来采取行动来控制业务。当接收到的CCM中的业务字段值与预定时间段从第二网元发送的CCM中的业务字段值不匹配时，第二网络元件将业务从其当前TESI移动到另一个TESI。

摘要： A method and Bridge in a Provider Backbone Bridge Network (PBBN) for enabling frames from a Higher Layer Entity attached alternatively to a Provider Instance Port (PIP) on an I-Component of a Backbone Edge Bridge or to a Customer Backbone Port on a B-Component of the Backbone Edge Bridge, to reach an intended entity in the PBBN. A Virtual Instance Port Service Access Point (VIP SAP) is configured for every VIP and every Higher Layer Entity configured on the I-Component. An Enhanced VIP Port Connectivity function utilizes the VIP SAP to tunnel customer-initiated Layer 2 Control Protocols (L2CPs). A Special Multiplexed SAP handles the frames of the Higher Layer Entity. A Service Instance Multiplex Entity utilizes the Special Multiplexed SAP to transfer frames between the PIP or the Customer Backbone Port and the entity inside the PBBN.

摘要： A Connection Fault Management (CFM) maintenance point and method for providing Data Driven Connection Fault Management (DDCFM) in CFM maintenance points in a communication network. A Reflection Responder, an RFM Receiver, and a Decapsulator Responder are implemented in existing CFM maintenance points. The Reflection Responder selects frames to be reflected, mirrors the selected frames if a Continuation option is set, and encapsulates the selected frames with Return Frame Message (RFM) OpCode. The RFM Receiver sends received RFM frames to an analyzer if addressed to the maintenance point and otherwise to a passive multiplexer. The Decapsulator Responder decapsulates Send Frame Message (SFM) frames and sends decapsulated frames toward the destination specified in each frame.

摘要： A method of providing protection switching on a backbone network includes configuring a service instance table for a first port of a first bridge. The service instance table includes a Virtual Local Access Network (VLAN) identifier entry for one or more service instances. The method also includes mapping data traffic received at the first bridge onto a first trunk by setting a VLAN identifier entry for a first service instance and transmitting data traffic to a second bridge on the first trunk in accordance with the mapping and monitoring the first trunk for faults by exchanging continuity check messages with the second bridge over the first trunk. The method additionally includes, upon detecting a fault, remapping data traffic for the first service instance by changing the VLAN identifier entry for the first service instance and transmitting data traffic to the second bridge in accordance with the remapping.

摘要： A system and method for providing Connectivity Fault Management, CFM, in a Provider Backbone Bridge Traffic Engineering, PBB-TE, telecommunication network utilizing Ethernet-based packet transport. PBB-TE point-to-point and point-to-multipoint services are identified, and PBB-TE maintenance points (31, 41) associated with the identified PBB-TE services are addressed. The addressed PBB-TE maintenance points are modified by adding a PBB-TE Service Demultiplexer (32, 42) to each PBB-TE maintenance point for identifying independent PBB-TE service instances. Basic CFM protocols are enhanced to duplicate the behavior of CFM protocols on virtual local area network, VLAN, based maintenance associations. The PBB-TE maintenance points may be Maintenance association End Points, MEPs, and Maintenance association Intermediate Points, MIPs.

摘要： A system and method of providing Ethernet protection switching in a PBB-TE Domain. Two PBB-TE trunks are established between a first B-component and a second B-component. Each trunk includes two unidirectional Ethernet Switching Paths (ESPs), each associated with a possibly different VLAN identifier. Data traffic is mapped onto the first PBB-TE trunk, where the first PBB-TE trunk corresponds to a working entity and the second PBB-TE trunk corresponds to a backup protection entity. Data traffic is sent via a first ESP of the first trunk associated with a first VID and a second ESP of the first trunk associated with a second VID. The two PBB-TE trunks are monitored for faults. Upon detecting a fault on one of the PBB-TE trunks, data traffic is remapped onto the other PBB-TE trunk via a third ESP associated with a third VID and a fourth ESP associated with a fourth VID.
