From: bnsw@Mitre-Bedford We are planning to hook up some LAN's to our ARPANET host using TCP/IP. We want to keep an account of the traffic (TELNET's, FTP's,TFTP's, and SMTP's) from the LAN hosts in using the ARPANET host. Has anyone written any accounting-type programs to gather usage stats for the hosts on a LAN that use/passthru an ARPANET host? Or, from a related viewpoint, to record ARPANET user statistics applicable for accounting from just the ARPANET host? We currently run UNIX 4.1bsd; we will soon be updating to ULTRIX (as a testbed 4.3bsd). Thank you for your time. Barbara Seeber-Wagner

From: "Paul D. Amer" <amer@UDel-Dewey.ARPA> 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.
