  • Switching redundancy control
    Patent number: 6700868
    Abstract: An apparatus and method for switching redundancy control which provides fast switching from a malfunctioning component to a redundant component with minimum data flow interruption for both transmitted and received data. The redundancy control system having an APS (Automatic Protection Switching) Hub, at least a working and a redundant tributary card, a bridge to provide identical traffic to the working and redundant tributary cards, a working and a redundant STM switching fabric, selectors within the working and redundant STM switching fabrics for selecting the traffic from the working tributary card to further process, a working and a redundant ATM switching fabric, a working and a redundant ATM processor and ATM selectors for selecting traffic needing cell switching from the working STM switching fabric to process further.
    Type: Grant
    Filed: February 4, 2002
    Date of Patent: March 2, 2004
    Assignee: Fujitsu Network Communications, Inc.
