The M/M/N/ ${\mathrm {m}}^{\mathtt {I}} {\rightarrow }\text{M}$ /M/L/ ${\mathrm {m}}^{\mathtt {II}} {\rightarrow }\text{M}$ /M/K/ ${{\mathrm {m}}^{\mathtt {III}}}$ levels respectively describe the three levels of data packet arrival, which include the bottleneck links and transmission hotspot Top-of-Rack (ToR) switches in the edge layer, the bottleneck links in the aggregation layer, and the bottleneck links in the transmission layer. This model can calculate the average delay of end-to-end data transmission, which can be used to better analyze the delays involved in the MPTCP Incast throughput collapse. Using NS3 software, we verified the accuracy of the proposed models. The experimental results show that the estimated delays of the proposed model are close to the actual measurement delays and that the edge layer delay proportion is higher. These results help to verify the MPTCP Incast performance bottleneck in the edge layer and provide a theoretical basis for further MPTCP Incast research.">
