QoS in grid networks is a very important issue. In this paper, we compare two scheduling algorithms of the Flow Aware Networking (FAN) architecture under Grid traffic. The metrics used to compare both serve to allocate the bandwidth. Additionally, we provide the comparison of one of the FAN architectures against DiffServ and under Grid traffic. Metrics studied here are average goodput and average delay. Finally, we provide a survey of the most important IP-based QoS architectures for Grid networks. We assume that Grid traffic is only composed by GridFTP sessions that arrive following a stationary Poisson process. We conclude that FAN based on the Priority Fair Queuing (PFQ) scheduling algorithm gets the better performance and that FAN architectures perform better than Diffserv.
