A fluid-flow characterization of Internet1 and Internet2 traffic

Abstract

We study the characteristics of Internet1 and Internet2 traffic at a network access point at a major USA university. With the use of fluid-flow modeling, we show that Internet1 and Internet2 traffic have different queuing behavior and that a small percentage of traffic on both networks largely contributes to this overall queuing behavior. We also demonstrate that buffer sizing, as a method to reduce loss, is largely ineffective for Internet2 traffic. These finding have implications for quality of service of Internet applications.
