Remote backup and some grid applications transfer large amounts of data over long distance networks. The throughput of TCP Reno and NewReno over LFNs (large fat pipe networks) is much smaller than application requirements. High speed protocols are being developed to overcome this problem. However, the fairness of these high speed protocols with conventional TCP (Reno or NewReno) is not sufficient...
We have developed a data transfer method that uses less reserved bandwidth on DiffServ AF networks. Our method consists of a dynamic QoS control method and a data transfer protocol that uses two kinds of TCP connections. We simulated the transfer of data using our method on a network simulator and found that it performed better than current methods. By reducing reserved bandwidth, our method will...
