The packet size distribution patterns of the typical Internet applications

The identification and classification of network traffic is an important prerequisite for network management, traffic engineering and other applications. To summarize the packet size distribution patterns of the Internet application traffic, we collected flow record data from the internet and analyzed the packet size distribution patterns of typical applications. Comparing the packet size distribution patterns of single application servers of typical applications, we found the differences of the packet size distribution in different servers. Then we clustered and analyzed different packet size distribution patterns for typical applications, and found that a typical Internet application could contain more than one packet size distribution pattern. Finally, from the characteristics of these applications, we explain the causes of these distribution patterns.
