Abstract
A multi-homed network node comprises an interface that is addressable using a primary network address and a secondary network address. Network packets identifying the primary network address traverse a first network path and packets identifying the second network address traverse a second network path that is routed physically separately from the first network path. A transport layer network protocol association is established in the network between a first node and the multi-homed node. One or more data messages are sent to the second node and identify the primary network address. Network feedback information indicates one or more performance characteristics of the first network path. In response, the data messages are automatically modified to identify the secondary network address.
