在多出口校园网中,基本解决了校园网内部用户访问外部资源速度慢的问题。但由于各网络运营商之间互联速度有限,非教育网用户在访问校园网资源时,访问速度还是非常慢。通过使用动态域名解析技术,在服务器中安装多块网卡设置多个IP地址,每个网络运营商一个。动态域名解析技术区分访问校园网用户的来源IP地址,根据用户的IP地址,域名解析服务器解析出不同的服务器IP地址,从而解决了所有网络用户访问校园网速度慢的问题。
In the multi-outlet campus network, the problem of slow access to external resources by users in the campus network is basically solved. However, due to the limited speed of interconnection between network operators, access to campus network resources by non-educational network users is still very slow. Through the use of dynamic domain name resolution technology, install multiple NICs in the server to set multiple IP addresses, one for each network operator. Dynamic domain name resolution technology to distinguish the source IP address of users accessing the campus network, according to the user’s IP address, the DNS server to resolve the different IP addresses of the server to address all the network users to access the slow campus network.
