为了保护重要数据,人们常把服务器置于内部网络与外网隔离.但实际常存在合法的外网用户需要访问内网服务器的情况.为此,采用“客户机-前置机-服务器”架构,实现内外网的隔离访问.采用数据摆渡,解决内外网的隔离通信问题;协议转换,兼容不同远程控制协议,有利于系统扩展;多节点接入控制,处理单节点宕机或多客户机接入问题,有效提高系统可靠性与性能.经过案例分析,表明该架构既能保证系统扩展性,又能保障系统的安全性和可靠性.
In order to protect important data, people often put the server in the internal network and external network isolation, but in fact there are often legitimate external network users need to access the intranet server.To this end, the use of “Client - Front-end - server ”Structure, to achieve isolated access inside and outside the network. The use of data ferry to solve internal and external network isolation communication problems; protocol conversion, compatible with different remote control protocol is conducive to system expansion; multi-node access control, single-node processing or multi-client Machine access problems, effectively improve the system reliability and performance.After a case study, it shows that the architecture can not only ensure system scalability, but also ensure system security and reliability.
