The present invention relates to a method, a device and a system for inter process communication, which comprises that the connection of a first resource, a second resource and the related resource is built. Simultaneously, an interactive transmission comprises that the data flow of a data element is identified with a multidimensional address port location number or multidimensional address port number, and a communication from related process to process with a space location is performed by a connectionless unreliable stream transmission method and a finite error check.
