Abstract
A method and system for resetting a network device. Specifically, in one embodiment, a method is disclosed for upgrading and/or reloading software for a network device with minimal disruption. The method begins by separating operations associated with layer two of an International Standardization Organization Open Systems Interconnect (ISO/OSI) reference model from other layers in the ISO/OSI reference model in a network device. Then, the software operations in layer two of the network device are reset. The software operations are reset while maintaining continuity for a communication session between the network device and other network devices coupled together through a network. Thereafter, for minimal disruption, execution of the software operations is recovered at layer two before continuity of the communication session s terminated.
