Full mesh status monitor
View Patent ↗A method for verifying full mesh status in a network is disclosed. The network includes endpoint entities in full mesh configuration. The method includes a step of maintaining a first value in the endpoint entities. The first value is related to counting of network endpoint entities. Another step in the method is maintaining a second value in the endpoint entities. The second value is related to counting non-operational transmission paths before a point in time. An additional step in the method is discovering an additional value related to counting non-operational transmission paths after the point in time. Yet another step in the method is comparing the additional value with the first value and the second value.
1. A provider edge device in an emulated Local Area Network, said provider edge device comprising:
a forwarder adapted to:
maintain connections with a plurality of other forwarders over a corresponding plurality of transmission paths;
employ an auto-discovery mechanism to maintain forwarder count information and status information of said plurality of transmission paths, wherein said auto-discovery mechanism facilitates reporting of full mesh status;
a bridge able to learn Media Access Control addresses; and
an emulated Local Area Network interface interposing and communicatively connected to said forwarder and said bridge.
2. The provider edge device as claimed in claim 1 wherein said auto-discovery mechanism employs a Type-Length-Value element related to counting non-operational transmission paths.
3. The provider edge device as claimed in claim 2 wherein said transmission paths are pseudo-wires.
4. The provider edge device as claimed in claim 3 wherein said emulated Local Area Network interface is adapted to permit said bridge to interface with said forwarder, said bridge being capable of communicating with client edge devices.
5. The provider edge device as claimed in claim 4 wherein said forwarder is configured to transmit Bridge Protocol Data Units on said transmission paths.
6. The provider edge device as claimed in claim 5 wherein said auto-discovery mechanism is a Virtual Private Local Area Network Service auto-discovery mechanism.
