  • Method and apparatus for protection of an optical network
    Patent number: 7573814
    Abstract: A method and apparatus for mesh based protection of an optical network is described. A method comprises protecting a first set of one or more optical sub-channels with automatic protection switching, utilizing a second and third set of one or more optical sub-channels to transmit traffic in accordance with a mesh process to transmit traffic, and transmitting traffic in the third set of optical sub-channels, which would have been transmitted in the second set of optical sub-channels, in accordance with routes determined by the mesh process in response to an alarm indicating a failure affecting the second set of optical sub-channels.

  • Method and apparatus for a routing information base
    Patent number: 7035256
    Abstract: A method and apparatus for managing an information routing information base is described. A method comprises managing a routing information base (RIB), the RIB including a first set of elements that indicate a set of destinations, a second set of elements that indicate a set of next hops, a third set of elements that indicate a set of interfaces, receiving a message that indicates a modification to a plurality of routes corresponding to a plurality of the first set of elements, and modifying a first relationship between one of the second set of elements and a first one of the third set of elements and a second relationship between the one of the second set of elements and a second one of the third set of elements in accordance with the message, the one of the second set of elements referenced by the plurality of the first set of elements.

  • Method and apparatus for switching data of different protocols
    Patent number: 6990121
    Abstract: A method and apparatus for switching data of different protocols through a network are described. In one embodiment, a method includes receiving data from a number of interfaces. Additionally, the method includes switching the data through a first switch fabric upon determining that the data is being processed as packet data. The switching of the data through the first switch fabric includes de-encapsulating a first number of protocol headers from the packet data. The switching of the data through the first switch fabric also includes encapsulating a second number of protocol headers from the packet data. Moreover, the method includes switching the data through a second switch fabric upon determining that the data is being processed as Time Division Multiplexing (TDM) traffic.
