ABSTRACT:
Knowledge of the computational context of a computer operating environment, for example, awareness of process threads, is used to route IP traffic in the presence of multiple active network connections. An additional protocol may be added to the network layer of an operating system in order to map certain computational contexts to particular network interfaces. Any process with identification parameters associated with a mapped computational context requesting data transfer via a communication network is bound to the network interface previously associated with the computational context rather than an alternate network interface that otherwise might be the default. Further, process threads created by a parent process thread may be caused to inherit the computational context of the parent thread in order to assign traffic to the same network interface. This routing framework may have particular application with respect to multihomed host devices, for example, mobile computing devices.
