Research on GridFTP Traffic Features

GridFTP is a secure and efficient data transfer protocol in Grid. This paper proposes a test scenario for the GridFTP traffic features. Firstly it gives a general description of the testbed traffic from the aspects of packet characteristics and throughput distribution; then analyses the self-similarity features of the GridFTP traffic and their decomposed data flows both in WAN and in LAN. Analysis results show that the parallel transfer of GridFTP increases both the self-similarity degree and the throughputs.
