Minimum delay path selection in multi-homed systems with path asymmetry

As mobile and fixed hosts are increasingly equipped with multiple network interfaces that enable multi-homing, there is significant current interest to seek appropriate method for access network selection. To address the presence of asymmetric forward-return path combinations in practice, we propose a simple but novel scheme to determine the one-way path with the lowest delay independently for both directions. This method provides delay sensitive multimedia applications with the lowest possible round-trip time in a multi-homed environment, compared to existing methods which assume path symmetry.
