Campus Network Construction And VLAN Technology In The Campus Network Application

In recent years,with the network technology,INTERNET's development and China Education and Research Network,nationwide more than 400 colleges and universities have set up their own network and forming part of the campus has access to the China Education and Research Network.Campus network construction has become the strength and level of development of university logo.With the college level,school size and school continued to expand and improve the building of a modern campus network reasonably practical to achieve internal and external information quickly and communicate to each other,so that teaching,research and management into the information technology,network,and thus improve the school level,has become an inevitable choice.This first chapter concentrates on the significance of the campus network construction, the overall goal of the campus network construction,the campus network construction,as well as the principles vlan technology in the campus network application and other issuesThe overall objective of the campus network construction is mainly to build the initial analysis of the application based on the campus network to develop,according to the realities of our hospital campus,I discussed the development of seven goals and the goal to make the appropriate introduction.The campus network construction principles,the campus network construction should follow the systematic,open,security,advanced the basic principles of Vlan technology in the campus network of technology-specific characteristics according to vlan set vlan technology in the campus network of the wider application.The second chapter concentrates on the campus network construction,several problems exist and the main technical presentations.ChapterⅢdeals with Zhuhai College of Jilin University campus network construction and management,this paper discusses our hospital through the campus network topology and network redundancy designed to introduce the core layer to introduce the hospital campus network construction of some relevant experience.And through out my hospital is currently being used by network management software and network management platform to introduce a hospital in the network management's experienceOur hospital mainly uses ESRP technology to build redundant core network,this paper mainly introduced the ESRP the difference between technology and VRRP technologies and through a detailed introduction of the association graph of the ESRP switch technology.According to my home network development,the text is also focused on the hospital how to use network management software and Lenovo Lenovo TCMS certified software to implement network management. The fourth chapter concentrates on the vlan technology applications through a comprehensive introduction to the concept of VLAN technology to describe vlan technology in the campus network applications.The window-dressing deposits(VLAN) technology gradually is already received by the people and the widespread application.In overseas,each standard formulation organization is seeking the manufacturer to fuse diligently theirs VLAN technology in the final product,realizes they respective window-dressing deposits strategy.The window-dressing deposits technology appearance is and the local area network exchange technology cannot separate.The local area network exchange technology caused the user to get rid of the traditional router,and in the very great degree former generation for the sharing medium which the people already knew very well.Along with ethernet and token ring commutation equipment average port price depression.Some far-seeing manufacturers start the vision to go to the large-scale local area.network exchange system.This network working suits the window-dressing deposits technology extremely the application,and becomes rapidly reduces the cost,increases the band width one effective method.However, the early switchboard does not have the route function.Said from some kind of degree that, it is only a high speed bridge.Therefore,exchanges in the primarily network in this kind, the router has played the main role in the definition broadcast territory process.The router may the very easy spanning different webpage,support reaches 500 users the broadcast territories.But,the exchange technology application has also had other some questions.The massive broadcast information brings the band width consumption and the network retard regarding very many users say are not allow to neglect.VLAN this kind of function caused the people before once has conceived the dynamic network organizational structure has become the possibility,and greatly impelled the overlapping work team's formation to a certain extent.That,actually what is the hypothesized work team? Speaking of a school,can aim at some concrete scientific research item frequently to set up one temporarily the work team which is composed by each department's personnel.They possibly come from the teaching department, administrative department and so on.Had the window-dressing deposits,in group's members has not needed to concentrate again to an office in.So long as they sit nearby own computer may find out other partner research situation.Moreover,the window-dressing deposits has brought the huge flexibility for us.When has the actual need,a hypothesized work team may arise at the historic moment.After the project had ended,the hypothesized work team may along with this vanishing.Thus,regardless of regardless of is to the user to the network administrator,VLAN all was again attractive.The switchboard appearance greatly vacillated the router in network status.New switchboard collection high speed bridge and high performance route in a body.Its growth tendency has gone far beyond the traditional router.Even if is the router production manufacturer also starts to hold this kind of viewpoint now:"Switch when you can,router can,router when you must.But on the other hand ",although the switchboard can provide the remarkable function in the network level foundation for the essential user,but,the switchboard still was in a short time same with the bridge,is unable to filter in the local area network the broadcast information.It only will be simple the broadcast information makes the copy,then the distribution gives each port.Does this can cause in the network frequently " transportation " to be packed like sardines,causes the high band width which the switchboard brings to sell at a discount greatly.Therefore,the user can not but use the router isolates this webpage and other webpages.The router function likely is one in view of the broadcast information firewall.Judging from this,switchboard itself cannot let the user abandonment router.A use window-dressing deposits superiority is supports the window-dressing deposits the switchboard to be possible in not to have in the router situation the very good control broadcast current capacity.In VLAN,only can in connect this window-dressing deposits client from the server to the client side broadcast information on the switchboard port to duplicate,but on other ports,broadcast the information to terminate.Only then these need spanning window-dressing deposits data packet only then can pass through the router.Under this working,the switchboard acts is the router role in fact.
