NDIS & Matlab based streaming TCP-transmission tools for high jitter conditions

Abstract

This study introduces testing results of multimedia TCP-traffic transmission approach by means of NDIS network driver, which provides TCP-Friendly protocol servicing on the data-link layer and able to simulate Internet-delays dynamic of the traffic transmission in local network. TCP-protocol improvement tasks for multimedia traffic flows transmission are considered. NDIS-based TCP-Friendly protocol implementation was supplemented by the traffic control mechanisms for high priority video traffic transmission and by the virtual buffer for Internet-delays simulation. For the Internet multimedia transmission an improved TCP-traffic control algorithm, which balances incoming-outgoing TCP-packets rates according to RTT-delays statistic, was implemented to NDIS-driver. Multimedia traffic sending, TCP-protocol flow control regulation and experimental results presentation tasks were provided in Simulink environment.
