  • Method and apparatus for process sync restart
    Patent number: 8423674
    Abstract: A method and apparatus for process sync restart is described. A computer implemented method comprises receiving a first set of data from a network process, determining death of the network process, clearing the first set of data if a time period expires, and synchronizing the first set of data with a second set of data if the time period does not expire, the second set of data received from the network process after the network process restarts.

  • Method and apparatus for virtual private networks
    Patent number: 7653074
    Abstract: A method and apparatus for virtual private networks (VPNs) is described. A computer implemented method comprises determining a set of endpoints for a generic routing encapsulation (GRE) tunnel, determining a key (the key corresponding to a VPN), dynamically establishing the GRE tunnel with the set of endpoints and the key, and processing a set of GRE traffic for the VPN.

  • Method and apparatus for variable rate pipes
    Patent number: 7209436
    Abstract: A method and apparatus for variable rate pipes is described. In one embodiment of the invention, a computer implemented method comprises allocating a pipe from part of a working channel and at least part of a protecting channel of a span of a bi-directional line switched ring (BLSR), the pipe having a bandwidth, transmitting a set of layer 2/3 traffic in the pipe, and reducing the pipe's bandwidth when a failure occurs in the ring.

  • Protection mechanism for an optical ring
    Patent number: 7016300
    Abstract: A method and apparatus for a hybrid variable rate pipe is described. In one embodiment of the invention, a computer implemented method of provisioning a non-BLSR protected layer 2/3 channel over a BLSR, provisioning a tunnel over the BLSR, and protecting the non-BLSR protected layer 2/3 channel between a first and second node of the BLSR with the tunnel is described.
