|Project Description: ||This project is the design and implementation of a MS-Windows-based network utility, WinTrace. WinTrace is able to perform three important functions: pinging a host and finding out the round-trip time, tracing the Internet path from a sending host to a destination host and finding out all the routers in between, and estimating the bandwidth of each link along the Internet path from a host to a destination host. WinTrace performs these functions by sending ICMP probe packets from a single source and then measuring round-trip times from responses received from destination hosts on probe packets. WinTrace can be used to find out the characteristics of the Internet links along a path and to detect the bottleneck link among all links. Determining the characteristics of Internet links can be very useful for future planning and extension of network services.
