  • Method, system, and computer program product for providing failure protection in a network node
    Patent number: 6941487
    Abstract: Multiple techniques for providing failure protection in a network node that includes primary and secondary control modules (CMs) are disclosed. One technique involves synchronizing configuration state information between the CMs by executing a configuration command within the primary CM and then executing the same configuration command within the secondary CM only if executing the configuration command within the primary CM does not cause the primary CM to fail. Another technique involves gleaning table entries from hardware-based forwarding tables and using the gleaned table entries to generate a software-based forwarding table in the secondary CM.
