DartCSim+: Enhanced CloudSim with the Power and Network Models Integrated

CloudSim is one of the most powerful simulation platforms for cloud computing. It supports the energy-conscious scheduling and network simulation in the latest version. However, it still faces several limitations: 1) Current CloudSim cannot support both the power model and the network model at the same time. 2) The network components in current CloudSim do not support power-aware simulation. 3) The simulation of migration does not take into account the network overheads. To overcome these limitations, we design and implement an enhanced cloud simulation platform called DartCSim+ that supports the energy-aware network simulation and network-aware live migration. Further, we also implement a resubmit mechanism for packets transmission to provide a more real network behavior to solve transmission failure which is caused by migration or network failure. Finally, three groups of experiments are performed to demonstrate the effectiveness of DartCSim+.
