Multihoming

Multihoming is the practice of connecting a host or a computer network to more than one network. This can be done in order to increase reliability or performance. A typical host or end-user network is connected to just one network. Connecting to multiple networks can increase reliability because if one connection fails, packets can still be routed through the remaining connection(s). Connecting to multiple networks can also improve performance because data can be transmitted and received through the multiple connections simultaneously, multiplying throughput and, depending on the destination, it may be possible to select a more efficient route through the choice of outbound network.
