The internet quality of service and reliability is currently managed by the TCP protocol. TCP is responsible for setting up the streams speed in a managed way, and if only a limited bandwidth is available, for slowing down the transmission rate of the streams. However, the internet is changing, no longer the dominant applications are HTTP, FTP or POP, but multimedia streaming. As the far most of them are based on the UDP protocol, which doesn’t the control features of TCP, the streams oppose a threat to TCP transmissions which are no longer able to manage the quality of service. This paper investigates the relationship between TCP and UDP traffic, by using a network simulation approach and the analysis of real network trace data to set the fundamentals for a more extensive exploration of the aggregated traffic issues and some solutions that could be developed. This research has been sponsored by France Telecom R&D UK.
