The Protocols My Network Speaks
Curious about what applications use up your bandwidth? Switch to the IP Sub-protocols tab and take a look:
This pie chart lets you quickly identify the protocols "spoken" on your network. Too much SMTP traffic? Your PC or other computers in your LAN segment send a high volume of e-mail correspondence. Too much FTP traffic? Perhaps because of many software downloads. While the chart displays only the most popular protocols by default, you can always click Customize and enter a new protocol and port number, for example, to have information on a popular peer-to-peer client or chat program.
