In this paper, we present design and implementation of a flow-level network simulator called FSIM+ (Fluid-based network SIMulator plus) for a network with heterogeneous flows transferred with different transport protocols: TCP,XCP, and UDP. In recent years, flow-level network simulators,which can perform significantly faster simulation than conventional packet-level network simulators, have been receiving attention. However, existing flow-level network simulators can only simulate persistent TCP flows. In this paper, by utilizing fluid models for several transport protocols, a flow-level network simulator FSIM+ for a network with heterogeneous flows is designed. Through several experiments using our FSIM+ implementation, we evaluate its effectiveness quantitatively. Both accuracy and effectiveness of FSIM+ are evaluated by comparing with the popular packet-level network simulator ns-2. Our findings include that our FSIM+ implementation achieves (1) less than 6% simulation errors in steady-state performance metrics, (2) approximately 10 times faster simulation, and (3) more than 20 times memory efficiency.
