Calculating RTT and throughput of a TCP connection

Development Envoirnment: Windows XP, IIS web server, Dot net Description: I need simple application which could read the time stamp of every packet of TCP for an existing TCP connection. Example: 5 Clients login to IIS webserver and starts downloading a file (5MB or 10MB) and during that time every packet from server is acknowledege by the reciever as its a TCP mechanism. I would like to calculate the RTT (Response Travel Time) of every packet sent to particular hosts means for all 5 connections. After that mean RTT should be calculated for each hosts. Thats the whole application.

Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Calculating RTT (Response Travel Time) of each TCP packet for particular TCP connection. (By implmenting TCP timestamp in option field of TCP header). Application could be easily developed by implementing TCP timestamp and at the end of connection averageing the RTT of each packet.
