摘要： A method and apparatus are disclosed for generating routing information in a data communications network. A first network element (such as a router) receives information relating to a second network element, such as another node or a network link. In response, the first network element determines whether the information relating to the second network element indicates a change in the network. When information relating to a second network element indicates a change in the network, the first network element determines a new shortest path through the network from the first network element for each network element in the network. After a delay, the first network element updates routing information for the first network element based on the new shortest path for the first network element. Preferably the delay is proportional to the distance of the first network element from the second network element.

摘要： In an embodiment, an apparatus for forwarding data in a data communications network having as components nodes and links therebetween comprises a network interface configured to couple to a data communications network having as components nodes and links therebetween; first logic which when executed is operable to receive a repair address; second logic which when executed is operable to compute a repair path from a repairing node to the repair address around a failure component on a primary forwarding path between the apparatus and a repairing node; and third logic which when executed is operable to propagate the repair address along a label switched path (LSP), comprising the repair path, to the repairing node. The apparatus offers improved efficiency in computing a repair path in a network around a failed component because unnecessary computations are not performed with the disclosed apparatus and approach.

摘要： A data processing apparatus is configured for initiating a not-via approach for creating repair path information for a first link between the first network node and a second network node; creating a list of other network nodes that the not-via repair path traverses; creating and storing entries in the FIB identifying repair addresses for the network nodes and that cause (a) packets directed to all addresses normally reachable through the first link to be encapsulated to the second node not via the first node, (b) packets directed to a not-via address that is normally reachable through the first link to be encapsulated to the second node not via the first node, and (c) dropping packets directed to a not-via address that is normally reachable through the first link when the not-via address is in the list; repeating the preceding steps for all other links.

摘要： A method is disclosed for synchronizing a data communications network. The data communications network comprises a plurality of existing nodes forming one or more synchronization domains and a node entering the network. Each existing node in a synchronization domain stores a common representation of the synchronization domain and is configured to flood the synchronization domain with domain representation information. In a synchronization domain identification step formed at the entering node, the entering node exchanges entering node domain representation information with a first neighboring existing node. The entering node identifies as a first synchronization domain common with the first neighboring existing node all neighboring existing nodes from which the entering node domain representation information is flooded back to the entering node.

After a delay, the first network element updates routing information for the first network element based on the new shortest path for the first network element. Preferably the delay is proportional to the distance of the first network element from the second network element.
