  • Method and system for minimizing disruption during in-service software upgrade
    Publication number: 20070162565
    Abstract: A method and a system for in-service software upgrade in a Hot Standby Redundant Distributed (HSRD) system are provided. A standby route processor in HSRD system is updated with upgraded software. The standby route processor is synchronized with an active route processor present in the HSRD system. The control of routing process is switched over to the standby route processor (with the upgraded software) from the active route processor. During the switchover, a minimal context forwarder on the line card begins execution and continues forwarding packets across a network, while a line card in the HSRD system is being reloaded and configured.
