Distributed Virtual Environment ( DVE ) is the product of the combination of virtual reality and computer network technology , it can break through the restrictions of time and space for people to analyze problems , solve problems, and work together to provide a new means of much international scientific community and engineering community concerned about cutting-edge technology , it has been very successfully used in the fields of military , aerospace, medical and entertainment , and in education and training, engineering design and manufacturing, e-commerce shows a good prospect . The DVE each simulation node interaction information through the network , to ensure the consistency of the virtual scene , therefore , network communication is an important topic in the DVE system design , an important direction of DVE study . SVC - Link is a virtual center of Southeast University DVE network interconnection support self-developed software systems, this paper SVC - Link system , the design and implementation of the key technologies of the DVE network interconnection support software system . First of all, introduced the concept of the DVE system , and analyzes the the DVE system network requirements and architecture . SVC - Link 's design, on the basis of the needs analysis , system consists of three major modules : the PDU processing module , simulation module and the space-time and event consistency module . Then, for each module design and implementation of the key technologies in detail , and finally through the correctness of the simulation demonstration system . System design process , the characteristics and difficulties of for DVE network communication , a better solution , the system is of great significance to the development and application of DVE DVE system development , it provides a convenient network interconnection development platform .
