Asymmetric path delay optimization in mobile multi-homed SCTP multimedia transport

ABSTRACT

Multimedia applications are very demanding of quality parameters from network provision, especially in a mobile wireless scenario. End-to-end delay is a primary concern for real-time applications. Much work have been done recently in order to fully exploit the multi-homing character of emerging wireless mobile systems addressing both communication performance as well as seamless handover. We propose an algorithm for path selection based on smallest delay that takes into account the dynamic asymmetry over the available routes. An example is provided showing how a multimedia application could benefit from this approach.
