Abstract:

Multipath transport system based on application-level relay (MPTS-AR) is a multipath transport system model based on application-level relay. It uses user datagram protocol relay server to establish multiple paths for point-to-point session and supports multiple services. A method was proposed to create MPTS-AR network simulation basing on INET Framework of OMNeT++ platform, including how to create network topology, to implement logical entities (user agent, relay controller, relay server), and to define and process messages. The key and difficult points about application program interface compatibility and supporting multi-service were also discussed. H.264 service based simulation was carried out. It is shown the correctness and effectiveness of MPTS-AR network simulation.

Key words: multipath transport, application layer relay, application program interface, OMNeT++, INET framework
