摘　　要：为了提高从CERNET访问公网资源的速度,目前国内高校校园网普遍采用了双出口或多出口的网络应用方案。然而,由于ISP之间策略路由的不同,导致接入不同ISP之间的用户互相访问速度较慢且性能不稳定,从公网访问校园网教育资源速度存在较大差异。利用智能域名解析技术,以南阳师范学院校园网三出口为例,通过配置Linux操作系统的BIND软件实现了智能域名解析系统。测试和应用结果表明,该系统是高效可行的,提高了从公网访问校园网教育资源的速度和性能,有助于提高现代远程教育的质量和区域教育资源的共享水平。In order to improve the accessing speed to public network resources from CERNET, solutions of double-output or multi-output have been applied to university ca mpus network.Because of different policy-based routing among the Internet Serv ice Provider,there are obvious differences in the accessing speed to campus net work resources.Taking the Nanyang Normal University multi-output network as an example,the intelligent domain name resolution system was realized by the conf iguration of DNS Server based on Linux Operating System.The practical test and application results indicate that the system is efficient and feasible.The syst em contributed to improve the the accessing speed to education resources in camp us network,and the quality of modern distance education as well.
