摘要
多样化技术已经成为可生存信息系统的一项重要的技术。分析了多样化服务器在失效情况下进行服务迁移所应具有的及时、安全、稳定性质;给出了满足这些性质的在多个网络中布置多样化服务器的算法。模拟实验表明,算法有良好的效果。
Diversity is one of the most important techniques in the research for the survivability technique of information systems.When the active server is fail,service on it should be supplied by another safe server steadily in time.In order to meet the requirement,an algorithm about how to allocate various servers in multi-LANs is given.The algorithm is proved to be effective.
