In the article, a validation module, being component of an integrated system supporting routing in software defined networks (SDNRoute), is proposed and thoroughly examined. The module allows for verification results provided by optimization before these are deployed production network. Routing policies validated their impact on network quality parameters against threat overloading (congestion).

Supporting quality of service (QoS) in wireless networks has been a very rich and interesting area of research. Many significant advances have been made in supporting QoS in single wireless networks. However, support for the QoS across multiple heterogeneous wireless networks will be required in the future wireless networks. In connections spanning multiple wireless networks, the end-to-end QoS...

Current trends in communication networks point to an aggregation of all kind of traffic (data, voice, etc) in the same transport technology. The emergence of real-time applications and the widespread use of wireless and mobile devices have generated the need to provide quality of service (QoS) support in wireless and mobile networking environments. QoS present a key problem of today’s mobile ne...

in this paper, a state feedback h¥ controller is proposed in order to design an active queue management (aqm) system based on congestion control algorithm for networks supporting tcp protocols. in this approach, the available link bandwidth is modeled as a time-variant disturbance. the purpose of this paper is to design a controller which is capable of achieving the queue size and can guarantee...
