Network connectivity management

摘要

Network connectivity management includes monitoring a circuit, wherein the circuit is a virtual connection between multiple networks via a provider core network. A device receives a plurality of network management messages associated with the circuit, and a determination is made regarding whether the circuit is experiencing a connectivity issue based on the network management messages. When it is determined that the circuit is experiencing a connectivity issue, then certain actions can be initiated.

1. A method, comprising:
identifying a circuit to monitor, the circuit including a virtual connection between multiple networks via a provider network and a physical connection between an access device and a provider edge device configured to provide an entry point to the provider network; configuring a maintenance entity association between the access device and the provider edge device such that at least one of the access device and provider edge device is configured to perform a fault determination and initiate a corrective action in response to a network management message of a first protocol, the association including at least one criterion for determining presence of connectivity issues; receiving, using at least one of the provider edge device and the access device, the network management message associated with the circuit; determining, by the provider edge device according to the at least one criterion of the association, if the physical connection portion of the circuit is experiencing a connectivity issue based on the network management message; and automatically in response to determining that the physical connection portion of the circuit is experiencing a connectivity issue, translating the network management message of the first protocol to an interface status of a second protocol to identify a pseudowire pathway associated with the physical connection portion experiencing the connectivity issue, placing the interface status of the identified pseudowire pathway in a failed state, and sending a release message thereby initiating a takedown of the identified pseudowire pathway to withdraw at least a portion of the virtual connection.
