To solve the problem of repetitive constructions of data exchange platform and to reduce the difficulty of implementation,a new construction mode of building multiple virtual data exchange sub-platforms on one common data exchange platform is proposed.First the multi-protocol label switching virtual private network(MPLS VPN) theories are studied.Then the architecture of virtual data exchange sub-platform(VEP) is presented.Several different virtual exchange platforms are created on a single common platform,and techniques such as user privilege isolation,database schema isolation,label switching,routing isolation,key isolation are used to ensure the isolation and security of data transmission on different sub-platforms.Additionally,center-based data exchange and routing mechanisms are used to convert the traditional point-to-point mode into a star model.It is proved in the project that using this construction mode,the repetitive constructions of data exchange platforms are avoided and the cost of implementation is well reduced.
