摘要： A method for creating an Operation Administration and Maintenance frame in an Ethernet/Transport Multi-Protocol Label Switch hybrid network. The method includes mapping values in an Ethernet Operation Administration and Maintenance data field in a protocol data unit (PDU) in a first Ethernet Operation Administration and Maintenance frame (Ethernet OAM frame) into a Transport Multi-Protocol Label Switch Operation Administration and Maintenance data field in PDU in a first Transport Multi-Protocol Label Switch Operation Administration and Maintenance frame (TMPLS OAM frame) and mapping values in first control parameter fields in the first Ethernet OAM frame into second control parameter fields in the first TMPLS OAM frame. The PDU in the first TMPLS OAM frame includes added extra fields as necessary, and the second control parameter fields further comprise preselected default information and routing information mapped from values stored in a memory.

摘要： A network environment including a provider network coupled to a first customer network site via a first access link and to a second customer network site via a second access link. The provider network is operable with the IEEE 802.1ag standard for propagating a remote link fault condition via an Ethernet Alarm Indication and Suppression (AIS) frame or a Continuity Check (CC) frame, which is translated into a locally compliant non-IEEE 802.1ag error delivery condition so that a management entity associated with the first customer network site is appropriately alerted.

摘要： A system and method for propagating fault information in an Ethernet OAM network having multiple levels of OAM domains. An Alarm Indication and Suppression (AIS) frame is generated by a Maintenance Intermediate Point (MIP) node upon detecting a fault condition in a first OAM domain, which is transmitted to one or more Maintenance End Points (MEPs) of the first OAM domain. Upon receiving the AIS frames, the MEP nodes are operable generate another AIS frame for propagating to an adjacent higher level second OAM domain. Responsive to the AIS frame from the lower level first OAM domain, any alarms caused in the second OAM domain due to the fault condition in the first OAM domain are suppressed.

摘要： A system and method for configuring Maintenance Intermediate Point (MIP) nodes of an Ethernet OAM network based on absolute level indicia as well as relative level indicia encoded in OAM frames generated by Maintenance End Point (MEP) nodes. A first OAM level field in a payload portion of an Ethernet OAM frame is encoded with an absolute OAM level associated with the originating MEP's OAM domain. A second OAM level field is encoded with a relative OAM level indicative of the number of OAM domain levels traversed by the Ethernet OAM frame.

摘要： A system and method for securing an Ethernet Connectivity Fault Management (CFM) domain defined on a Virtual Local Area Network (VLAN). In one embodiment, the scheme includes, responsive to registering by an external port with the VLAN, whereby the VLAN is extended to include the external port, monitoring by a boundary Maintenance End Point (MEP) node of the Ethernet CFM domain to determine if bidirectional control frame flow (e.g., Continuity Check (CC) frame flow) is observed thereat; and, responsive to determining by the boundary MEP node that there is no bidirectional control frame flow therethrough, generating an alarm indicative of a potential breach of the Ethernet CFM domain by the external port.

摘要： A system and method for monitoring end nodes using Ethernet Connectivity Fault Management (CFM) in an access network. In one embodiment, a broadband access server (BRAS) is operable to generate an Ethernet CFM frame that includes a query message with respect to a particular end node. An interworking function (IWF) entity associated with an access node that services the particular end node is operable to interpret the Ethernet CFM frame and construct a corresponding query message in a native protocol compatible with the particular end node. Upon receiving a reply message from the particular end node, the IWF entity constructs a suitable reply Ethernet CFM frame for transmission to the BRAS, wherein the reply Ethernet CFM frame includes a response corresponding to the reply message from the end node.

摘要： A domain configuration system and method operable in an Ethernet OAM network having multiple levels of OAM domains. A port of a first end bridge of the network is configured as a first MEP node belonging to a predetermined OAM domain having a particular level. GARP or CC frames are transmitted from the first MEP node in a forward attribute registration process towards the remaining bridges of the network. A port of a second end bridge of the network is configured as a second MEP node of the predetermined OAM domain. In a backward attribute registration process, GARP or CC frames are transmitted from the second MEP node towards the remaining bridges of the network. Responsive to the frame flow, ports in bridges disposed between the first and second end bridges are automatically configured as MIP nodes having the particular level.
