Technique for setting network communication parameters

Techniques are disclosed for providing a bandwidth control interface that displays the relative amount of bandwidth assigned to each application executing at a computer device. By displaying the relative amount of bandwidth, the interface allows the user to easily determine how the available bandwidth is allocated among the applications, and whether the allocation provides for efficient network communication. The bandwidth control interface also allows the user to adjust the relative allocation of bandwidth to the executing applications. The user can thereby control the relative amount of bandwidth that is allocated to each application by a network interface device.
