Comparative analysis on TCP and UDP network traffic

With the increase of network bandwidth, more and more new applications like audio, video and online games become the major force in network traffic. Based on real-time considerations, these new applications mostly used UDP as transport layer protocol, which made UDP traffic increase. While previous traffic measurements were generally based on TCP and ignore UDP protocol. This paper made a continuous 12-hour on-line measurement on a backbone environment. Firstly, it did a detailed analysis on TCP and UDP in transport and application layer, including total number of the flow, length distribution, duration distribution, and flow rate distribution. Secondly, gave a detailed classification on application layer protocols according to flow size, length, and speed. Our analysis and conclusions can present a data support for other studies as the traffic classification, network behavior analysis, and the network design etc.
