802.1ag – Connectivity Fault Management

Independent ESPs may be identified by the same VID value 1ab some other parameter in their identifying 3-tuple is different. It may be determined whether a conflict exists block Typically, the first 4 octets of CFM 1af are considered header information. The communications network of claim 1wherein at least one node stores configuration information that specifies node ports on which LLDP data units LLDPDUs containing Management VID type, length, values TLVs will be transmitted, and wherein the configuration information is restored from a non-volatile memory upon re-initialization of a management system for the communications network.

Therefore, no TE state information needs to be sent over the control protocol unless the TE tunnel is in down state and the labels are withdrawn.

Sultan, Robert, et al. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate one or more embodiments described herein and, together with the description, explain these embodiments of the invention. Data communications network for the management of an ethernet transport network.

In one embodiment, the proxy 20 encapsulates an LSP ping 36 with a path label 34 specifying a path e. As illustrated, bridge may include, among other things, a controllerline interfaces – 1- 2- 3and – 4 collectively referred to as line interfacesand an interconnect The communications network component of claim 17wherein the Management VID value field comprises a management VID that has been provisioned to the communications network component.


Smart c8 for multi-client bidirectional optical channel 8802 scheme. For purposes of discussion, the MEP will be described in reference to a network device, such as a bridge or a switch. However, additional checks may be incorporated to test the bridge domain itself.

As technologies continue to advance, OAM is becoming a challenging endeavor. Interconnect may include, for example, a switching fabric or another form of a connection e.

The logic also comprises a connectionless traffic module that supports VLAN-based communications represented by the dashed arrows.

CFM – XMind – Mind Mapping Software

The apparatus of claim 17 further comprising means for receiving a response to said connectivity verification message, said response comprising a packet generated at a remote proxy.

Network problems may arise d render devices or transmission paths between devices inoperable. The destination node receives the connectivity verification message and sends an acknowledgement message back over the same f8 of hops defining the path to the originating node.

The LSP ping 36 identifies a complete path defined by a set of hops, therefore enabling a ping and ping reply between nodes and across a path. The apparatus of claim 12 wherein the processor is further configured to select an operation for said forwarding device, map said operation to said proxy label, and transmit said mapping to the forwarding device. The period at which CCMs may be transmitted is user-configurable. The method of claim 1 further comprising receiving: The non-transitory computer-readable medium of claim 15, where the instructions d comprise: The 820 20 also identifies the proxy address originating node in the connectivity verification message.


In the IEEE Upon receiving the message, the destination node sends an explicit acknowledgement response message to the originating node. Thus, the operation and behavior of the aspects were x8 without reference to the specific software code—it being understood that software and control hardware can be designed to implement the aspects based on the description herein. At step 56 the proxy 52 receives path information from the provider edge device 48 FIGS.

CFM header may include information similar to the information described above in connection with FIG.

Rather, the concepts described herein may be implemented in other protocols or standards. In other implementations, MEP may be implemented elsewhere in bridge For example, if a MEP is detected as being down e.

Program memory 74 is one example of a computer-readable medium. For example, as previously described, maintenance domains may be assigned with different MD levels.


Operations, administration, and maintenance data packet and related testing methods. Further, it may be possible to omit blocks within process Typically, the first 4 octets of CFM packet are considered header information. Systems and methods for multiple r8 voice and data communications using intelligently bridged TDM and packet buses and methods for performing telephony and data functions using the same.

It is to be understood that the format shown in FIG.
