Abstract

It is an important issue to provide the reliability as well as to balance the traffic load for the multihomed networks. In this paper, we deal with two most important factors, traffic load balancing and redundancy. The assigned weight for each link is dynamically computed according to the arrival and service rates via arrival rate dependent (ARD). By employing the adaptive-ARD (A-ARD) mechanism, the network performance in terms of average waiting time was further improved. The simulation result showed that more than 20% performance improvement was achieved by comparing A-ARD to RR, WRR and ARD with arrival rate 80 packets per second. Through the proposed redundancy scheme of A-ARD, the reliability of the packet transmission was fulfilled.
