BMDO Virtual Data Center (VDC) network traffic analysis

This paper discusses an analysis of the end-to-end delay of files traversing the Ballistic Missile Defense Organization (BMDO) Virtual Data Center (VDC) network. The BMDO VDC network is an intranet based on World Wide Web (WWW) Internet technology with downloadable file sizes much larger than those typically traversing the World Wide Web (WWW). The largest downloadable file in the WWW is typically less than 100 kbytes, while the downloadable file size in the BMDO VDC network is as large as 20 Mbytes. This paper discusses the effect of large files traversing an intranet using WWW Internet technology. The end-to-end delay was derived as a function of file transfer size, fixed latency of the local area and wide area network links, data rate, packet arrival rate, and the number of users. These results were compared with several simulation results. A quick-look analysis indicates that an intranet using WWW Internet technology that incorporates a large downloadable file size requires a careful handling of the network parameters (i.e., data rate, file sizes, and traffic load).
