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： A method of constructing a repair path around a non-available component in a data communications network having, as components, nodes having a network address and links there between comprises the step, performed at a participating node, of receiving from a notifying node in the network, a notification identifying the notifying node and components through which the notifying node can be reached. The method further comprises the step of deriving, from the notification, a network repair address for use in the event of non-availability of a component identified in the notification. The method further comprises the step of constructing a repair path for the repair address.

摘要： A method of updating a label-switched path for forwarding data in a data communications network in response to a change in a network comprises the step, performed at an updating node of receiving notification of a network change, of constructing a post-change label-switched path in the changed network. The method further comprises, after termination of a first period, forwarding data using the post-change label-switched path.

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.
