A QoS architecture model for variable services demands
Drago Žagar, Snježana Rimac-Drlje · International Convention on Information and Communication Technology, Electronics and Microelectronics · 2001
The complex applications and services, for example applications with multimedia content, could during the communication demand different level of QoS. The variations of QoS, and QoS degradations, are not necessarily the result of the overall traffic in the network, but they can also be a consequence of using the devices with different possibilities, different networks, or mobile devices. The QoS architectures and their control systems offer a possibility to serve the user with guarantied service end-to-end. They usually offer a number of control functions for different situations that can happened. By adopting highly sophisticated QoS mechanisms, we can improve a network ability to offer the high quality of service while efficiently uses raw network resources.
