Application based egress interface selection

Abstract

A method of selecting an egress interface for a source process running on an electronic device is provided. The device implements a TCP/IP stack utilized by a plurality of applications for sending network packets. The method receives a packet from a particular application in the plurality of applications to send to a network destination over a socket tagged with an identifier of the particular application. The method compares the socket tag with a set of network egress interface tags. Each network egress interface tag is associated with a network egress interface in a plurality of network egress interfaces. Each network egress interface tag includes the identifier of an application that utilizes the network egress interface. The method selects a network egress interface with a tag that matches the socket tag. The method sends the packet to the network destination through the selected network egress interface.
