Abstract
Active Queue Management is the key to congestion control and enhancing IP QoS. MRED can support MPLS networks and take advantage of classifying mechanism of DiffServ and mark different businesses with different drop precedence. However, it has several limitations. In this paper, I-AMRED is proposed in order to reduce packet loss ratio and raise throughput in MPLS networks based on DiffServ and MRED. Thus, it can also adaptively control average queue length, and diminish sensitiveness to control parameters and improve stability with the service flow bursts. Two experimental schemes are designed and implemented on NS-2. Experimental results show that I-AMRED algorithm increases throughput of networks and largely decreases packet loss ratio of AF PHB traffic. When data traffic is very large or sharply increased, the performance of throughput and packet loss ratio is improved greatly, and has better stability.
