A CCM database may be updated block Alternatively, only a de-aggregation label may be advertised to minimize the label bindings c8 to the proxy. 8022 purposes of discussion, assume that bridges – 1 and – 6 include MEPs 1 and 2.

In this case, the connectivity verification packets generated at the proxy are pushed onto a TE tunnel. In this manner, any discrepancies in management VID provisioning can be detected and resolved. Furthermore, the proxy allows for greater scaling opportunities since modification of the proxy would not disrupt the existing device for which it is providing proxy capabilities.

The RAM 1agg used to store volatile data and perhaps to store instructions. The components and methods described above may be implemented on any general-purpose network component, such as a computer, router, switch, or bridge, with sufficient processing power, memory resources, and network throughput capability to handle the necessary workload 1aag upon it.

The PE devices 4850 provide pseudowire emulation, enabling customer edge CE devices 4042 to communicate over the network.

To verify the Management VID is provisioned identically throughout the network, embodiments support exchanging Management VID information between adjacent nodes. In the case where an LDP session is not available between the forwarding device and proxy, the following process is performed. The method of claim 5, further comprising: Although implementations associated with the concepts described herein may be described in reference to the IEEE Each proxy 2022 allows for the running of connectivity verification without impacting performance at the provider edge device 14 Network address transition methods and systems.

The proxy 20 also identifies the proxy address originating node in the connectivity verification message. The method of claim 8wherein transmitting the constructed linktrace message to a second node comprises: Further, it will be appreciated that this process may be implemented even where legacy MEPs i. MEP may be implemented in one or more line interfaces If static programming of labels is used, the proxy 52 logs into the provider edge device 48 and sends CLI Command Line Interface commands directly.


The following detailed description refers to the accompanying drawings. Connectivity Fault Management, June These messages are also commonly referred to as continuity and consistency checks, OAM Operations, Administration, Maintenance messages, connectivity probes, connectivity pings, continuity checks, loopback test, or path consistency checks. US USB2 en This makes it unnecessary to introduce additional protocols to the Providing management services e. Thus, the operation and behavior of the aspects were described without reference to the specific software codeā€”it being understood that software and control hardware can be designed to implement the aspects based on the description herein.

The label mapping may be selected based on the type of hardware or application. Modifications and variations are possible in light of the above teachings or may be acquired from practice of the teachings.

These checks involve sending a message to a remote node requesting an acknowledgement. The same reference numbers in different drawings may identify the same or similar elements. For example, in some embodiments, the management traffic control module enables the network component to generate a CFM message that is propagated as connectionless traffic.

This achievement stems from the intrinsic characteristics of the technology: System and related methods for automatically configuring a computing system. 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.

Some networks support both connectionless frame transfer e. Smart mechanism for multi-client bidirectional optical channel protection scheme.

It is to be understood that the applications described herein are only provided as examples and that the proxy may also be used in other applications. Proxies 5254 are connected to or located at provider edge devices 4850respectively. The packet is received at the destination node and is sent to the route processor for processing. VCCV thus provides several means of creating a control channel over the pseudowire, between the PE routers that attach the pseudowire.


Thus, each node that implements a LLDP agent either comprises or has access to non-volatile memory from which such truth values can be restored. According to one aspect, a method may include receiving, by a first entity, a message from each entity of a group of second entities to which the first entity is a member, the message including a network identifier associated with each second entity, selecting a first network identifier for the first entity based on the network identifier associated with each second entity, transmitting a first message including the first network identifier to each entity of the second entities to determine whether the first network identifier is available, and assigning the first network identifier to the first entity if a conflict message is not received from any of the second entities in response to the first message.

Further, it may be possible to omit blocks within process Packets sent from the proxy appear at the forwarding device with the de-agg label. The communications network component of claim 11wherein the logic transmits a management VID TLV having a zero value in the management VID field if a management VID has not been provisioned to the communications network component. What is claimed is: For purposes of discussion, process will be described as being performed by MEPs associated with bridges – 1- 6and – 7.

The proxies 2022 shown in FIG. OpCode field may specify the format and meaning of the remainder of CFM packet If one of the provider nodes is the PLR, the proxy does not need to know about the state of the TE tunnel.

However, 82 checks may be incorporated to test the bridge domain itself. The concepts described herein provide for auto-provisioning of network IDs e. Method and system for providing a mobile IP network with non-path dependent intra domain quality of service.

Independent ESPs may be identified by the same VID value if some other parameter in their identifying 3-tuple is different.
