ABSTRACT:
A method, system, apparatus, and signal-bearing media for determining connectivity information for routers running on servers that are attached to a device. A router is resigned in favor of a corresponding router at another server when the corresponding router has better connectivity to the device, where partial connectivity is better than no connectivity, and full connectivity is better than partial connectivity.
