IP usually use 1500 for protocols that send blocks of data, such as FTP and HTTP. On the other hand, a lot of Web servers use less to make it look like you're getting better performance. (You see the Web page arrive in chunks). Telnet sends one character per packet, by default, which adds up to 64 bytes on an Ethernet segment (it requires padding). DHCP packets are often about 200-300. Routing protocols vary. RIP uses 512. Others use 1500. SMTP varies. It will send 1500 bytes if the message is that long, but often it's not. In other words, you need to know the application to answer the question. I have always claimed, in fact, that an average packet size if a somewhat useless statistic. What you really want to know is if applications are sending what you expect them to send. (This requires doing a baseline analysis.) In my Top-Down Network Design book, I provide quite a few examples of packet sizes for typical applications. That might help you. >dlsw is 512 Really? Why does DLSW use only a 512-byte packet? FTP and HTTP would often have to be fragmented if that were the case. I used to know DLSW but I don't any more....
