Abstract :
Aiming at the problem of static bandwidth allocation (SBA) algorithm and most dynamic allocation algorithm (DBA) can´t support QoS, and the low utilization ratio of system bandwidth, in this paper, we study a residual bandwidth iteration dynamic allocation (RBI-DBA) algorithm for multilink access network system bandwidth allocation, in RBI-DBA, the residual bandwidth can be iteration allocated many times, until all of RTUs bandwidth request can be fulfilled or no longer have the residual bandwidth. Simulation experiments demonstrate that RBI-DBA increase bandwidth utilization ratio and reduce packets delay.
