    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 system and method for enabling a disabled port on a device such as a Two Port Medium Access Control (MAC) Relay (TPMR), which relays MAC frames in a communication network. When a link in the network fails, the TPMR disables the port due to operation of a link failure propagation protocol. When the TPMR detects that the failed link is repaired, the TPMR stops transmitting link failure Packet Data Units (PDUs) and transmits a Link Failure Terminating PDU to other connected TPMRs in the network. Receipt of the Link Failure Terminating PDU indicates the failed link is repaired and all ports disabled as a result of the failure should consequently be enabled.

    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, and is assigned an I-SID value that is universally recognized to identify the L2CPs. 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 system and method of demultiplexing Provider Backbone Bridging Traffic Engineering (PBB-TE) service instances. The method is used when monitoring service instances between a first bridge port and a second bridge port by exchanging CFM frames over each service instance. The CFM frame is received by the second bridge port where the complete ESP-3-tuple is demultiplexed. The CCM frames may be demultiplexed by a Full Traffic Engineering Service Instance Multiplex Entity which demultiplexes both the source address value and destination address value of the CCM frames.

    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 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.
