  • Supporting OAM on protecting connections in shared mesh protection environment
    Patent number: 8908533
    Abstract: A method for detecting the liveliness and synchronizing the control-plane and data-plane on protecting connections in a shared mesh network environment through methods for probing the protecting connection conditions by sending in-band messages; and synchronization of control plane and data plane by using LSP-ping messages on the protecting connections.
    Type: Grant
    Filed: September 29, 2011
    Date of Patent: December 9, 2014
    Assignee: Infinera Corporation

  • Activation signaling in transport networks
    Patent number: 8670302
    Abstract: A method comprising the steps of receiving a signal indicative of a failure of a working connection in a mesh network having a headend node, a tailend node and an intermediate node, and having a protecting connection, and transmitting an activation message via the protecting connection from at least one of the headend node and the tailend node to the intermediate node for activating the protecting connection.
