Abstract: An MPTCP Incast performance evaluation model based on a queuing network is provided. The invention establishes a multi-level collaborative MPTCP Incast data transmission performance evaluation model of M/M/N/mI?M/M/L/mII?M/M/K/mIII the queuing network based on a multi-homed FatTree topology and a Markov property of an MPTCP data scheduling process. M/M/N/mI, M/M/L/mII and M/M/K/mIII respectively characterize a three-level collaborative process of arrival of data traffic groups in a bottleneck link of an edge layer, a transmission hotspot ToR cluster and a bottleneck link of a convergence layer.
