It argues that consolidation intercommunication infrastructure, uniform standard, centralization management can bring right benefit. In additional, from security cost control parameter q of several technology intercommunication infrastructures comparison, the technology with smallest security cost control parameter q should be choose first depend on the model analysis when the development intercommunication infrastructure.
