Tele-Communication (Telecom) Terms Glossary and Dictionary
Capping refers to the activity of ISPs (Internet Service Provider) to limit (capping) the accessing speed of cable modem so that cable modem ISPs can easily distribute bandwidth among users. The upload cap in particular is intended to discourage users to run big servers. In general, these caps are also put in place to make the system more robust. At slower speeds, packet loss is usually lower and the system can handle worse signal quality.
