    摘要: Route advertisement requests made by a customer are received at route provisioning center (20) to effect either advertisement of a newly provisioned route or withdrawal of an existing route. In the case of a request to advertise a newly provisioned route, the request is subjected to validation, and if unable to be validated, the request is rejected. Upon validation of a new route advertisement, or following receipt of a request to withdraw an existing route advertisement, the customer-entered request is entered into an official routing database (26) for subsequent propagation to network access providers (14, 16 and 18). Periodically, a check is made to verify that the customer-entered request remains active.

    摘要: A method and apparatus for identifying a Label Distribution Protocol (LDP) flapping event in a communication network are disclosed. For example, the method counts a total number of LDP session up events, a total number of LDP session down events, a total number of link up events, and a total number of link down events within a predetermined time interval. The method then determines an occurrence of a LDP flapping event using the plurality of total numbers.

    摘要: A method and apparatus for diagnosing and isolating label-switched-path impairments in a network are disclosed. For example, the present method receives an impairment notification indicating a potential impairment for at least one label switched path between a source device and a destination device. The method then identifies all routers along each of the at least one label switched path. The method then determines automatically whether each of the routers along each of the at least one label switched path is enabled for exchanging label mapping information. Finally, the method identifies at least one of the at least one label switched path as being impaired if at least one of the routers on the switched path is deemed not enabled for exchanging label mapping information.
