Abstract
A system and method to estimate and to limit usage time of network applications by a centrally located router is provided. The router first modifies the Domain Name System (DNS) protocol's Time To Live (TTL) values to a fix value, then it counts the number of DNS queries for an application. Number of queries multiplied by the fixed TTL value gives estimated duration of the application.
