Keywords: QoS, bandwidth limitation


Current data networks carry a multitude of data types. These include high-definition video streams and other data sensitive to network delays as well as real-time voice transmissions.

Active network node equipment fulfills requests, while providing network management without affecting the data availability. Starting out from this model, a new idea is based on moving the network bandwidth control at the user’s communication interface. This paper presents a new approach to setting up QoS parameters based on local upstream traffic limitation management. This approach is quite useful in providing a certain guaranteed bandwidth for the users. So, this software ensures a specific network bandwidth according to with the rights coming up from their association with a certain ”Active Directory” group of users.  The necessary active network equipment in terms of basic QoS management can be replaced by a local application for data traffic limitation, while for the involved participants the remaining bandwidth for other communications has a higher degree of availability. An efficient bandwidth control can be implemented when extracting specific AD fields and transferring pre-calculated user related parameters to a local running limiter.
