摘　　要：采用非阻塞IO技术和动态负载均衡机制,将普通机群连接起来实现大规模的文献资源数据处理和网络服务。机群中的每个节点都有自主学习的功能,根据实际的转发情况不断的调整自身的转发控制表,删除多次转发失败的节点,从总服务器上读取新的转发目标节点,有效的降低了本地网络上信息查询负载,使得每个节点以最少的试探查询次数转发负载,从而在整体上提高服务器的性能。通用型的TCP服务器系统可以方便地通过系统提供的接口编写定制类型的Web服务器或者C/S服务器。Using non-blocking IO technology and dynamic load balance to connect common computer group, large-scale data processing and network service are realized. Every node in the cluster group has the ability to learn, they modifying themselves＇ forwarding control table according to the real forwarding success rate, delete nodes which forwarding failed, and update new node from the forwarding control table server, by this way can improving the server＇s performance, make every node forwarding success at the least query test times. For TCP server of common use can design your web server or C/S server by the interface supplied by system conveniently.
