  • Patent number: 9025437
    Abstract: Grouping pseudowires based on hardware interfaces and configured control paths enables improved pseudowire failover performance. Signaling status changes (e.g., from standby to active status) is facilitated by using group IDs for the pseudowire groups, thereby enabling improved failover performance when there is disruption in the network.
    Type: Grant
    Filed: July 2, 2013
    Date of Patent: May 5, 2015
    Assignee: Cisco Technology, Inc.

  • Publication number: 20110242988
    Abstract: An example method includes identifying a fault condition in a network, and evaluating pseudowires affected by the fault condition in order to make a determination as to whether an aggregate failure occurred in the network for a group of pseudowires. The method also includes communicating a group message indicating that the group of pseudowires is associated with the fault condition. The group message includes a group identification (ID), which identifies the group of pseudowires, and the group message includes a pseudowire group label identifying an in-band aggregate channel. More specifically, the pseudowire group label can be applicable to static pseudowires. In more detailed embodiments, the group ID identifies the group of pseudowires that are associated with an attachment circuit, a label switched path, or a port. Internal mappings can be maintained such that a plurality of pseudowires is mapped to individual interfaces of network elements in the network.
