摘　　要：随着计算机、通信、网络技术的迅速发展,全球信息化的步伐越来越快,网络信息安全问题已成为影响国家长远利益而亟待解决的重大关键问题。人们对信息传输的安全性、及时性、有效性要求越来越高。安全隔离与信息交换系统部署于物理隔离的两个或多个网络之间,提供安全可控的信息交换,与此同时也限制了业务的支持种类。通过扩展安全隔离与信息交换系统,实现了系统支持识别源的多对一单播功能和组播功能,并给出了相应的应用实例。扩展后的安全隔离与信息交换系统,可以通过具体配置项灵活地对其通讯方式进行控制,并且组播功能可实现内外网不同组播组之间的通信,增强了安全隔离与信息交换系统对实际业务需求的适应性。With the rapid development of computer,communication and network technology,the pace of global informatization is getting faster and faster.The problem of network information security has become an important and urgent problem affecting the long-term interests of the country.People are demanding higher and higher security,timeliness and effectiveness of information transmission.Security isolation and information exchange systems are deployed between two or more physically isolated networks to provide secure and controllable information exchange,while at the same time limiting the types of business support.By extending the security isolation and information exchange system,the multito-one unicast function and multicast function of the system supporting identification source are realized,and the corresponding application examples are given.The expanded Security Isolation and information exchange system can flexibly control its communication mode through specific configurations,and the multicast function can realize the communication between different multicast groups in Intranet and extranet,which enhances the adaptability of the security isolation and information exchange system to the actual business needs.
