  • High capacity router having redundant components
    Patent number: 8649256
    Abstract: A router includes multiple routing engines. If the active routing engine fails, a backup one of the routing engines detects the failure and assumes the role of active routing engine. A redundancy controller circuit, connected to the multiple routing engines, facilitates the selection and switching of the routing engines. Portions of the packet forwarding engine, in addition to the routing engine, may be redundantly implemented. The active routing engine controls the selection of the redundant portion of the packet forwarding engine.
    Type: Grant
    Filed: September 3, 2010
    Date of Patent: February 11, 2014
    Assignee: Juniper Networks, Inc.
    Inventors: Anis Haq, Lawrence Hui, Scott Chew, Unmesh Agarwala, Michael Beesley
