网络拓扑选择计算机网络拓扑有很多种，包括总线拓扑、环形拓扑和星形拓扑。

There are many kinds of computer network topologies, including bus topology, ring topology and star topology. All computer media in a linear topology connect the entire network from beginning to end. This is the simplest of all network topologies. All stations are connected by a circle of cables, which looks like a circle. Currently, the star topology is the most commonly used in the construction of various network systems. The advantages of the star topology structure are very prominent. It is mainly used as a node that will not affect the operation of the entire network when the network fails. This allows the network as a whole to provide high reliability and aggregation measures. Its performance is very suitable for the enterprise network application environment. Essential elements necessary for enterprise network construction. The design of the network structure is the basis of the entire network system design. An excellent network structure design plan is conducive to improving the performance, reliability and future network expansion capabilities of the network, and can effectively reduce the difficulty of maintenance. The network structure topology designed in this paper Figure 4-1

网络拓扑选择计算机网络拓扑有很多种，包括总线拓扑、环形拓扑和星形拓扑。线性拓扑中的所有计算机介质从头到尾串联整个网络。这是所有网络拓扑中最简单的一种。所有的站都是由一圈电缆连接的，看起来像一个圆圈。目前，星形拓扑是各种网络系统建设中最常用的。星型拓扑结构的优点非常突出，主要作为节点在网络故障时不会影响整个网络的运行，这使得网络作为一个整体可以提供高度的可靠性和汇聚措施，其性能非常适合企业网络应用环境，具有企业网络建设所必需的要素。网络结构的设计是整个网络系统设计的基础，一个优秀的网络结构设计方案有利于提高网络的性能、可靠性及将来网络的扩展能力，并能够有效的减少维护难度，本论文设计的网络结构拓扑图如图4-1

The advantage of star topology is very prominent, mainly as a node in the network failure will not affect the operation of the entire network, which makes the network as a whole can provide a high degree of reliability and convergence measures, its performance is very suitable for enterprise network application environment, with the essential elements of enterprise network construction. The design of network structure is the basis of the whole network system design. An excellent network structure design scheme can improve the network performance, reliability and future network expansion ability, and can effectively reduce the maintenance difficulty.
