A New Marker for Proportional Bandwidth Allocation
In this paper, we study why the traditional traffic markers cannot provide precision of marking and proportional fairness in the current Differentiated Service (DiffServ) networks. To solve these problems, we propose the Innovation Three Color Marker(ITCM) algorithm. Our proposed ITCM algorithm calculates both the long term average rate and the instantaneous rate of traffic when marking the packet. Moreover, our proposed algorithm achieves the proportional fair sharing among aggregates by marking the packet as yellow with probability in proportion to CIR. We have compared the performance of our proposed ITCM marker with traditional markers. Simulation results show that our proposed algorithm performs better than traditional markers in the case of undersubscription. It is not only achieves the target rate, but also achieves proportional fairness of sharing the excess bandwidth.
