1 互连网络1.1 基本概念1.1.1互连网络。 互连网络是一种由开关元件按照一定拓扑结构和控制方式构成的网络,用来实现计算机系统内部多个处理机或多个功能部件之间的相互连接。1.1.2 互连函数。 为了反映不同互连网络的连接特性,每种互连网络可用一组互连函数来描述 如果将互连网络的N个输入端和N个输出端分别用0,1,2,…,N-1来表示,则互连函数表示相互连接的输入端和输出端号之间的一一对应关系.或者说,存在互连函数f,在它的作用下,输入i应与f（i）相连,这里: 0<=i<=N-1表示互连函数常用两种方法:函数表示法和输入输出对应表示法。基本互连函数有如下几种: 1）恒等置换: 相似文献

网络组建中常用路由器、单臂路由、三层交换机等三层设备连接不同的网段,上述网络设备之间互连并运行路由协议可以实现设备之间所连网段的互访,因此三层网络设备之间正确互连是网络组建的基础。对初学者来说路由器之间互连比较易于理解,但路由器与三层交换机或单臂路由与三层交换机等其他情形的三层设备之间如何互连就不易掌握。利用“功能等价法”可以解决这一问题,即将物理端口充足的路由器之间的互连方法确定为标准方法,通过和标准方法进行功能类比来确定其他情形三层设备互连的配置方法。 相似文献

VPN是一门新的网络技术,公司不需建立自己的专用线路,只要公司局域网已经接入了Internet,并且在Internet上有自己固定的IP地址,就可以通过Internet网或其他公用网络实现异地之间两台计算机或局域网之间的互连,通过建立一个安全的隧道连接,使得外部计算机或局域网可以安全访问公司内部局域网。本文对VPN做了简单介绍,提出了建立公司VPN服务的方法,并给出了常用系统VPN的设置方法。 相似文献

实验室模拟局域网互连 总被引：1，自引：0，他引：1
有关计算机网络技术方面的实验项目比较多,相对来说,局域网组网实验比较容易实现,但不同的局域网进行互连却不那么容易,尤其是在现有的实验室条件下。为学生设计的网络互连方面的实验大都因实验环境难以架设而无法付诸实施,主要的问题在于,DDN线路租费和帧中继等设备价格太昂贵,实验室不可能提供DDN、FR、ATM等广域网络。所以,寻求一种价廉的、易于实现的方式架设局域网互连环境,就显得十分必要。本文作者采用一种电话专线方式替代DDN专线,用一对高速基带Modem替代帧中继等昂贵设备,在实验室内模拟实现了不同局域网的远程互连,现介绍… 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献

The awareness of individualism can be traced back to the period of American Revolution when the Declaration of Independence was produced.It expressed basic beliefs concerning freedom,equality,democracy,privacy and the relationship between people and government,which were exactly what the philosophy of individualism mostly dealt with at that time.This paper is to exploit the essence of individualism by analyzing the Declaration .The analysis enables us to reconsider its significance to the issue of America human rights and foreign policies. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
