Abstract

A system and method make quality measurements in a network to determine if a Service Level Agreement is breached. The system includes a plurality of routers for routing traffic through the network, means for taking measurements on a path between a first router and a second router, and means for charging at least one of the plurality of routers when data related to the measurements falls below a target value.
