局域网(LAN)的迅速增长使得越来越多的相互独立的计算机进入到网络环境。而在Internet、TCP/IP日益普及的今天,如何访问LAN范围之外的网络资源已经成为一个新的热门话题。越来越多的局域网开始通过各种各样的方式连入Internet,并通过应用TCP/IP协议访问Internet资源。例如,企业内部网通过DDN、X.25、分组交换等方式进入Internet;高等学院的众多教学局域网、主机系统则通过逐步形成的校园网经路由器访问Internet。Novell网作为当今最流行的计算机局域网络,一直广泛地应用于企事业单位及各高等院校的局域网环境中,它在局域网市场上仍占据着统治地位。尽管Novell网的应用范围非常广泛,但大多数服务仍然停留在文件服务的水平上。因此如何利用现有的设备为广大Novell用户提供更丰富的服务和资源,
The rapid growth of local area networks (LANs) has enabled more and more independent computers to enter the network environment. In the Internet, TCP / IP is increasingly popular today, how to access network resources outside the LAN has become a new hot topic. More and more LANs start to connect to the Internet in various ways and access Internet resources through the application of TCP / IP protocol. For example, the intranet accesses the Internet through DDN, X.25, packet switching and other means. Many higher education teaching LANs access the Internet through the gradually formed campus network via routers. As the most popular computer local area network today, Novell network has been widely used in LANs of enterprises, institutions and colleges and universities. It still occupies a dominant position in the LAN market. Although the Novell network has a very wide range of applications, most services remain at the level of file services. Therefore, how to use the existing equipment to provide more Novell users with more abundant services and resources,
