A network router initially communicates over a primary data path. Upon detection of an error condition associated with the primary data path, the network router initiates a layer 2 switch such that the communication occurring over the primary data path is switched to a backup data path. The layer 2 switch is preferably transparent to a layer 3 portion of the network router.

Network router that efficiently switches between a primary data path and a backup data path

An integrated processor-controlled router and switch fabric architecture provides connectivity between local area network (LAN) ports of an Ethernet switch serving a plurality of local area network users and a wide area network (WAN) interface that provides connectivity with the internet. Packets received from user ports of the Ethernet switch contain priority-representative information. Packets delivered by the processor-controlled router to the WAN interface are prioritized in accordance with the priority-representative information.

Integrated router/switch-based mechanism for mapping COS value to QOS value for optimization of LAN-to-WAN traffic flow

A router in one embodiment of the present disclosure has first router logic and boot logic. The first router logic is configured to operate the router, and the boot logic is configured to receive updated router logic from a network and to perform a first reboot. The boot logic is further configured to initialize deactivation of the first router logic and initialize activation of the updated router logic during the first reboot such that a plurality of functions for the router are enabled during execution of the updated router logic. The boot logic is also configured to perform, in response to an error during execution of the updated router logic, a second reboot such that at least one of the functions is disabled.
