Abstract

See full text

A host node connected to a network using an Internet Protocol automatically identifies multiple adapters connected to the same network, preferably by broadcasting a Dynamic Host Configuration Protocol (DHCP) request for assignment of an IP address on a first adapter, and listening to the request on a second adapter, thereby determining that both adapters are on the same network. The host preferably causes an IP address to be generated for one of the adapters, and automatically configures the adapters to share the IP address thus generated as a virtual IP address, assigning one of the adapters as a primary adapter. Preferably, the host automatically detects deactivation of the primary adapter and switches the virtual address assignment to a different adapter.
