Amer" Regarding your question about if anyone has written any accounting-type programs to gather usage stats for the hosts on a lan: At Delaware, we have a project sponsored by the Office of Naval Research to perform a characterization of LAN traffic. Over the past year, we have developed a system that monitors the ethernet, saves one minute summaries (snapshots) of traffic on a disk, and analyzes the traffic offline. Our analysis includes a characterization of the higher level protocols used, the amount of intra vs. interLAN traffic, a summary of packet interarrival times, and lots more. We are currently finishing a characterization of 2 months worth of LAN traffic involving approximately 80 million packets. Our results will be written up in a report available hopefully by the end of the summer.
