Does anyone have any hard numbers that document which application protocols are used most over ARPANET (i.e. what TCP & UDP port numbers are seen most often)? It'd be nice if these numbers included both numbers of packets, and number of bytes (since FTP packets are likely to be larger than TELNET packets). The last time I saw any numbers for any part of the Internet, numbers of packets were split: SMTP 30%, FTP 30%, TELNET 30%, and OTHER 10% (this is from memory, so don't take the percentages too literally - it was the relationship between them that I was concerned about at the time).
