Ever wonder what\u0027s causing the slow down?  You are not alone.  Millions of users bemoan sluggish downloads and slow email but rarely know the cause of the delays.\n\u003C\/p\u003E\n\u003Cp\u003EResearchers at Georgia Tech have developed a technology to find out the how the Internet is performing from the \u0022regular\u0022 end-users\u0027 perspectives. With this information, they can design and develop network solutions to relieve these bottlenecks.  To do this, they need volunteers for the \u003Cstrong\u003ENETI@home\u003C\/strong\u003E project, which stands for \u0022network intelligence.\u0022 \u003C\/p\u003E\n\u003Cp\u003ECurrently industry and academia use data on the Internet\u0027s performance measured at various router points out in the Internet, before it reaches the individual user (see http:\/\/weather.uci.edu). Georgia Tech researchers think a better approach is to find out how the Internet is performing from the user\u0027s point of view-at each personal computer.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022We think a better solution is to measure performance at the individual user level to determine what affects Internet traffic, but currently this data doesn\u0027t exist. That\u0027s where \u003Cstrong\u003ENETI@home \u003C\/strong\u003Ecomes in,\u0022 says George Riley, professor of electrical and computer engineering and adjunct professor in the College of Computing.  \u0022We need thousands of computer users to use our free \u003Cstrong\u003ENETI@home \u003C\/strong\u003Esoftware to help us gather this data.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ETo do this, Riley and graduate student Robby Simpson developed an open source software application that collects network performance statistics such as average response time, average round trip time, connection times, download times, and number of packets and bytes sent and received. The application then regularly reports these statistics to the \u003Cstrong\u003ENETI@home \u003C\/strong\u003Eserver at Georgia Tech.  \u003Cstrong\u003ENETI@home \u003C\/strong\u003Eis designed to be an unobtrusive software system that runs quietly in the background with little or no intervention by the user. The reports sent to Georgia Tech are also stored on the user\u0027s computer, so the user can see what statistics are gathered.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ENETI@home \u003C\/strong\u003Eusers select a privacy level that determines what types of data will be gathered, and what will specifically not be reported. The application currently offers three privacy levels- low, medium, or high-allowing the user to choose the level of detail of the information collected, such as fully reports IP addresses, reports only the network portion of the IP address or does not record any IP addresses.\n\u003C\/p\u003E\n\u003Cp\u003EThe researchers will collect the data and make it available to other network researchers. They expect the data will show trends of Internet performance or indicate security problems such as a huge spike of activity that might be caused by worms.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Among the other things we anticipate this data will help us with is to give a reasonable picture of what Internet users demand of the network during normal activities.  This will lead to better simulation models of Internet users behavior, leading to more accurate simulations.  For example, with our \u003Cstrong\u003ENETI@home\u003C\/strong\u003E data, we might observe that a typical user experiences an average round trip time of 100 milliseconds and traverses on average 8 Internet routers.  We would then construct our simulations to choose connection endpoints that have similar metrics,\u0022 says Riley.\u003C\/p\u003E\n\u003Cp\u003EComputer users around the world are encouraged to download the free application to their computer, to help researchers in the quest for improved Internet performance. At www.neti.gatech.edu, users will find detailed instructions and answers to questions about the \u003Cstrong\u003ENETI@home \u003C\/strong\u003Eeffort. \u003Cstrong\u003ENETI@home \u003C\/strong\u003Eparticipants also may receive an optional NETI map, a mapping application that displays a geographical map of where their computer is connected on the Internet. \n\u003C\/p\u003E\n\u003Cp\u003EIn April the research team will present a paper about \u003Cstrong\u003ENETI@home \u003C\/strong\u003Eat the international conference PAM 2004 Passive \u0026amp; Active Measurement Workshop, to be held near Nice, France.
