Abstract: In view of the traditional method to design the network interface cross platform transplant, there is no good compatibility between the design of the protocols. Middleware technology and linear planning and scheduling of network interface based on cross platform transplantation extended control design method, to construct the cross platform network architecture, network interface in a cross platform porting the physical system and the communication system analysis, the middleware technology of network node structure optimization deployment design. Then the scheduling algorithm for linear programming is the network interface in a cross platform porting dynamic extended resource scheduling design, order based implementation of network interface cross platform porting expansion control design method of improved is proposed in this paper. The experimental results show that the method is used to optimize the design of the network interface cross platform transplant, which effectively improves the compatibility and convergence of the system.
