The following graph indicates the ratio of packets measured between the different interactive protocols discussed in this memo, offering some sense for the current utilization of various interactive protocols on the Internet today. These results must be taken with a grain of salt; given the dynamics of these protocols these ratios may present a poor picture of actual use of particular applications. For example, an automated FTP script used for daily replication may generate 100,000 packets in a minute while an hour long end-user interactive research session with WWW on particle physics could yield as few as 1,000.
