针对已有的解决 Internet服务器性能瓶颈和可靠性问题的方法所存在的不足 ,提出基于 IP层负载平衡调度的解决方法 ,将一组服务器构成一个可伸缩的、高可用的虚拟 Internet服务器 .通过在服务机群中透明地加入和删除结点以实现系统的伸缩性 ;通过检测结点或服务进程故障和正确地重置系统达到高可用性 .详细讨论了虚拟 Internet服务器的体系结构、设计方法和实现技术 ,并给出了相应的性能测试结果 .关键词 Internet服务器 ,负载平衡 ,高可用性 ,网络地址转换 .
Aiming at the shortcomings of the existing methods to solve the performance bottleneck and reliability problems of Internet server, this paper proposes a solution based on load balancing scheduling in IP layer, which makes a group of servers form a scalable and highly available virtual Internet server. Service clusters to join and delete nodes transparently to achieve the scalability of the system, by detecting the node or service process failure and correctly reset the system to achieve high availability.The virtual Internet server architecture, design methods and implementation techniques , And gives the corresponding performance test results. Key words Internet server, load balancing, high availability, network address translation
