隧道技术是一种利用网络基础设施将数据从一个网络
传送到另一网络的方法.被传送的数据(或称为有效负载)
可以是另一协议的帧(或数据分组).隧道协议不是当源节点
产生一帧时就立即发送,而是先用一个附加的报头对帧进行
封装. 这个附加的报头 提供路由信息 使得这个被封装的
负载可以通过通信子网
被封装的分组在隧道端节点间被路由. 封装分组通过
互联网时所走的逻辑通道被称为隧道. 封装帧抵达通信子网的
目的节点后 就被解封装 并被转发到目的终端上
隧道技术包含数据分组封装 传送和解封装的整个过程
传送网络类型不限 因特网就是一个公共的互联网络 同时也是
最广为人知的互联网络的一个实例. 除此之外 也有很多
企业网络使用隧道技术通信的例子. 尽管因特网是最
覆盖最广性价比最高的网络之一 本文中提到的因特网
可以被任何用作传送网络的其他公共或私有网络替代
隧道技术已经出现了一段时间 成熟的技术实例有:基于
IP网络的SNA隧道技术. 当SNA网络流量通过企业IP网络
传送时 SNA帧被加上IP和UDP报头
Novell Netware系统使用的基于Ip网络的IPX隧道技术
当一个IPX分组被送往NetWare服务器 或IPX路由器时
服务器或路由器为IPX分组加UDP和IP报头 然后把它
发送到IP网络上 目的地的IP-IPX转换路由器 去掉
UDP和IP报头 把分组转发给IPX目的端
近几年出现了新的隧道技术 本文主要探讨这些技术
包括
点对点隧道协议 这个协议可以为IP IPX
和NetBEUI流量加密 并添加IP报头 通过企业或
公共IP网络（如因特网）传送
第二层隧道协议 L2TP可以为IP IPX NetBEUI
流量加密 然后通过任何支持点对点数据报传输
的网络进行传送 如 IP网络 X.25 帧中继 ATM
网络
IPsec隧道模式 IPsec隧道模式为IP数据分组加密
并为分组添加IP报头 然后通过企业或公用网络（如因特网）
进行传输

Local area data networks，normally referred to simply as local area networks or LANs，are used to interconnect distributed communities of computer-based DTEs located within a single building or localized group of buildings.For example，a LAN may be used to interconnect workstations distributed around offices within a single building or a group of buildings such as a university campus.Alternatively，it may be used to interconnect computer-based equipment distributed around a factory or hospital complex[1].Since all the equipment is located within a single establishment，however，LANs are normally installed and maintained by the organization.Hence they are also referred to as private data networks.
The main difference between a communication path established using a LAN and a connection made through a public data network is that a LAN normally offers much higher data transmission rates because of the relatively short physical separations involved[2].In the context of the ISO Reference Model for OSI，however，this difference manifests itself only at the lower network dependent layers.In many instances the higher protocol layers in the reference model are the same for both types of network.
Before describing the structure and operation of the different types of LAN，it is perhaps helpful to first identify some of the selection issues that must be considered.A summary of some of the these issues is given in Fig. 14-5.It should be stressed that this is only a summary;there are also many possible links between the tips of the branches associated with the figure[3].
1.Topology
Most wide area networks，such as the PSTN，use a mesh(sometimes referred to as a network)topology.With LANs，however，the limited physical separation of the subscriber DTEs allows simpler topologies to be used.The four topologies in common use are star，bus，ring and hub.
The most widespread topology for LANs designed to function as data communication subnetworks for the interconnection of local computer-based equipment is the hub topology, which is a variation of the bus and ring[4].This is shown in Fig. 14-6，sometimes it is called hub/tree topology.
2.Transmission media
Twisted pair，coaxial cable and optical fiber are the three main types of transmission medium used for LANs.
3.Medium access control methods
Two techniques have been adopted for use of the medium access control in the LANs.They are carrier-sense-multiple-access with collision detection(CSMA/CD)，for bus network topologies，and control token，for use with either bus or ring networks[5].
CSMA / CD is used to control multiple-access networks.Each on the network“listens” before attempting to send a message，waiting for the“traffic”to clear[6].If two stations try to send their messages at exactly the same time，a“collision”is detected，an both stations are required to“step back”and try later.
Control token is another way of controlling access to a shared transmission medium that is by the use of a control(pertnission)token.This token is passed from one DTE to another according to a defined set of rules understood and adhered to by all DTEs connected to the medium.A DTE may only transmit a frame when it is in possession of the token and，after it has transmined the frame，it passes the token on to allow another DTE to access the tranamission medium.

[2] that引出表语从句。

[4] 很少文献资料提出“集线”拓扑，一般都归并为星形拓扑之列。
[5] CSMA / CD访问控制方式，由于集线器和双绞线的使用，它也用于星形拓扑结构;令牌控制方式用于总线拓扑结构时指令牌总线网(token bus network)。

局域数据网一般简称为局域网，用于在一幢楼内或局限在楼群范围内把分散的基于计算机数据终端设备互连在一起。例如，一个局域网可以把一幢楼里或像大学校园内各个楼里的各个办公室的工作站连在一起。另外，局域网也可以把分布在工厂或医院建筑群中的计算机设备连在一起。由于所有这些设备都是一个单位的，因此局域网一般也由这个单位负责安装和维护。于是这类局域网也叫做专用数据网。
用局域网方式建立的通信线路和通过公用数据网连接的线路两者的主要区别在于：因为局域网连接的设备之间相对来说距离较近，因而数据传输速率高得多。但是在ISO的OSI参考模型中，这种区别只在较低的与网络相关的几层比较明显。而很多实例表明，在该参考模型高层协议中，这两种网络是没有区别的。
在叙述几种不同类型的局域网的结构和工作之前先认识一下必须考虑的有关问题可能是很有帮助的。图14-5概括了其中的某些问题。应该强调的是，这仅仅是一个概括，因为图中各分支之间还可能有很多链路。
1.拓扑结构
大多数广域网，如公共电话交换网(PSTN)就使用网状(有时称为网络)拓扑结构。而局域网，由于用户数据终端设备相距很近，可采用简单的拓扑结构。常用的有星形、总线、环形和集线器等4种拓扑结构。
应用最广的、用于本地计算机设备互连以进行数据通信的局域网拓扑结构是集线器拓扑结构。这种拓扑结构是总线和环形拓扑结构的变种。图14-6展示了为这种拓扑结构，有时也称为集线器/树形拓扑结构。
2.传输媒体
双绞线、同轴电缆和光纤是局域网采用的3种主要传输媒体。
3.媒体访问控制方法
局域网中采用了两种媒体访问控制技术。它们是用于总线网络拓扑结构的带冲突检测的载波侦听多路存取(CSMACD)和既可用于总线又可用于环形网络的令牌控制技术。
CSMA/ CD用来控制多路存取网络网络上的每个站点在试图发送信息前先“侦听”，等待通路空闲。如果两个站点在同一时刻要发送信息，将会检测到冲突，这两个站点必须各自“后退”一步，以后再重试。
令牌控制是另一种用令牌去控制访问共享传输媒体的方法。该令牌按所有连入媒体的DTE都知道并遵守的一套确定的规则从一个DTE传向另一个DTE。当某一DTE掌握这一令牌时，它才能传送一帧数据，而在传送完该帧之后，要将令牌释放，以便其他DTE访问该传输媒体。

To what extend do you agree or disagree? In this period of communication, computer has been used in all kinds of fields widely, and plays a particular role in our lives. Especially computer has become more and more important in ecational field, therefore dozens of people considered teachers could be replaced computers that will go with the current of the times. The above point is certainly wrong; this essay will outline three reasons. From Joozone.com. The main reason is that people's brain better than computer. Firstly, people design all kinds of computer's programs. Secondly, computer doesn't have logistic ideation. Computer only can defend on that designer inputted computer's programs to judge a question's right or wrong. In other words, computer can't defend on thinking that computer independently analyzes a question's right or wrong. In case, designer inputted programs that are wrong. Computer output the result that also will be wrong. If this kind of problem happened in classroom, students would be infused plenty of wrong information. Another reason is that computer's programs designed software of ecation that could be amended difficultly. If software of ecation of bugs were found, commonly these of problems couldn't be solved in the classroom. The software was amended that means total of program were corrected, not only parts of program were inserted or amended usually. Last but not the least reason is computer is mechanical, it couldn't be suited all kinds of students and different demands. As students' intellect is different, same of software couldn't base on every status of student to set a perfect project. In conclusion, computers couldn't instead of the position of teachers in the classroom, however computer is an absolutely good helper for teacher. 追问： 翻译下啊 我还要中文的 我不会翻译 回答： 在 计算机 广泛应用于教育，一些人认为没有老师在课堂上发挥重要作用。到何种程度你同意或不同意？ 在此期间的通讯，计算机已被应用于各种领域广泛，并发挥在我们生活中的特殊作用。特别是 电脑 已经成为越来越重要，在教育领域，因此，教师数十人认为可以取代电脑，将与当前的时代。上述的当然是错误的，这篇文章将阐述三个原因。 最主要的原因是，人们的 大脑 比电脑。首先，人们设计计算机的各种程序。其次，计算机没有 逻辑思维能力 。电脑只能在该设计师保卫输入计算机的程序来判断问题的对错。换句话说，计算机不能捍卫独立思想，计算机分析问题的正确或错误。在情况下，输入的 程序设计 是错误的。计算机输出的结果，也将是错误的。如果这发生在课堂这类问题，学生将注入大量的错误信息。 另一个原因是， 计算机程序设计 的教育可以修改艰软件。如果 教育软件 的漏洞被发现，通常这类问题不能得到解决，在课堂上。该软件进行了修订，这意味着总计划得到纠正，不仅在 程序部分 ，插入或修改通常。 最后但并非最不重要的原因是计算机的机械，它不可能适合学生和各种不同的要求。此外，学生的智力是不同的，相同的软件无法对每一个学生的身份的基础设置一个完美的项目。 总之，不能代替教师在课堂上的地位电脑，但电脑是教师绝对的好帮手。 希望你能满意o(∩_∩)o
