Adaptive rate control (ARC) over DVB-RCS on satellite links

The Digital Video Broadcasting Return Channel via Satellite (DVB-RCS) is a flexible technology offering broadband Internet access to a large community of users with a relative low cost. However, the spreading of the multimedia network is required the mechanism to guarantee a certain level of Quality of Service (QoS) to the end users. This paper will propose the ARC mechanism which is acting like a gate to control bandwidth by investigating the available channel parameter, and delay time for reused the other available channels at Network Communication Center (NCC). The other co-parameters such as number of packet drop, mean queue time and throughput are investigated in situation of congestion. The results of ARC mechanism will compare with regular mechanism, as Connection Admission Control (CAC) mechanisms. Finally we obtained the impressive results over the proposed mechanism.
