The invention relates to an MPTCP robustness analysis optimization method and system based on a cascade failure model. The method comprises the steps of determining an initial communication load and a communication capacity of each node in an MPTCP multi-path transmission system by obtaining the MPTCP multi-path transmission system built by a simulation experiment platform; determining a corresponding communication state of each node according to the initial communication load and the communication capacity of each node; determining a failure node according to each communication state; carrying out load redistribution on each failure node to obtain a communication load of the adjusted node; according to the communication load of the adjusted node, judging whether the node of which the load is adjusted is invalid or not; if yes, determining a failure node, and performing load redistribution again; if not, the cascade failure is ended, and a cascade failure model is obtained. According to the invention, the rob
