求英语强人帮忙翻译摘要！

虚拟局域网（VLAN），是一种通过将局域网内的设备逻辑地而不是物理地划分成一个个网段从而实现虚拟工作组的新兴技术，在功能和操作上和传统的LAN基本相同。虚拟局域网技术是目前网络界最热门的技术之一，也是交换网络中最重要的技术之一，它的出现是和局域网的交换技术的发展分不开的。VLAN的出现打破了传统网络的许多固有观念，使网络结构变得灵活、方便。IEEE于1999年颁布用以标准化VLAN实现方案的802.1Q协议标准草案。虽然VLAN并非最好的网络技术，但这种用于网络结点逻辑分段的方法正为许多企业所使用。
通过使用VLAN，我们可以获得很多好处，例如提高管理效率；控制广播数据；增强网络的安全性；减少站点的移动和改变开销等。在使用带宽、灵活性、性能等方面，虚拟局域网（VLAN）都显示出很大优势。虚拟局域网的使用能够方便地进行用户的增加、删除、移动等工作，提高网络管理的效率。但是由于各主要网络设备生产厂商在虚拟局域网方便的技术不完全相同，甚至它们的体系都互不相容，很多用户也许被VLAN技术的众多优点所吸引，但也被这种混乱局面弄的无所是从。为此，电气和电子工程师协会（IEEE）通过了一系列有关VLAN的标准，很大程度上的促进了VLAN的发展，本文也介绍了相关的协议和标准。
VLAN交换技术是基于OSI参考模型第二层的，但要实现VLAN间通信就要使用第三层设备，如路由器或者是具有路由功能的交换机。在网络发展的初期，网络中只有10%～20%的信息在VLAN之间传播，但随着多媒体技术在网络中应用的迅速普及，VLAN之间信息的传输量增加了许多倍，如果VLAN之间的通信问题解决得不好，将严重影响网络的使用和安全。由于路由存在着转发速度慢、价格昂贵等缺点，于是三层交换技术应运而生。三层交换技术是路由和交换合二为一的技术，在VLAN的通信和管理中，您会发现三层交换机将比路由器更具性价比且更加有效率。

关键词：虚拟局域网，VLAN，路由，交换，广播域
还有一段：
最后提出了VLAN技术在企业网中的整体解决方案。包括：VLAN子网的划分，VLAN ID的规划， VLAN之间的路由策略(集中式路由和分布式路由)，VLAN之间的访问控制等。

楼下的哥们真快，什么翻译软件这么牛X啊，自己翻的就佩服了

Answer 1

The virtual local area network (VLAN), is one kind through but is notphysics divides the local area network in equipment logic a each onewebpage thus to realize the hypothesized work team's emergingtechnology, basic is same in the function and the operation andtraditional LAN. The virtual local area network technology is one ofpresent network most popular technologies, also is exchanges in thenetwork one of most important technical, its appearance is and thelocal area network exchange technology development cannot separate.The VLAN appearance has broken traditional network many inherentideas, causes the network architecture to change nimbly, isconvenient. IEEE promulgates in 1999 with standardized VLAN therealization plan 802.1Q agreement standard draft. Although VLAN by nomeans best network technology, but this kind uses in the network pointlogic partition method to use for many enterprises. Through uses VLAN, we may obtain very many advantage, for exampleenhancement management efficiency; Control broadcast data; Enhancementnetwork security; Reduces the stand the migration and the changeexpenses and so on. In aspect and so on use band width, flexibility,performance, the virtual local area network (VLAN) all demonstratesthe very big superiority. The virtual local area network use canconveniently carry on work and so on user increase, deletion,migration, enhances the network management the efficiency. But becauseeach main network equipment production merchant facilitates in thevirtual local area network technical quite same not less than, eventheir system all incompatible, perhaps very many users are attractedby the VLAN technology multitudinous merit, but also is made by thiskind of chaos non- is from. Therefore, the electricity and electronicengineer the association (IEEE) passed a series of related VLANstandard, in the very great degree promotion VLAN development, thisarticle also introduced the related agreement and the standard.
The VLAN exchange technology is based on OSI reference model second,but must realize VLAN to correspond must use the third equipment, ifthe router or is has the route function the switchboard. In thenetwork development initial period, in the network only has 10% ~ 20%information to disseminate between VLAN, but along with the multimediatechnology in the network the application rapid popularization,between VLAN the information transmission quantity increased manytimes, if between the VLAN correspondence question solves is not good,seriously will affect the network the use and the security. Becausethe route exists retransmits the speed slowly, the price is expensiveand so on the shortcoming, thereupon three exchanges technologiesarise at the historic moment. Three exchanges technologies are thetechnologies which the route and the exchange two in one, in theVLAN correspondence and the management, you can discover threeswitchboards will compare the router having price also are moreeffective than.
最后一段
Finally proposed the VLAN technology in the enterprise network wholesolution. Including: VLAN sub- net division, VLAN ID plan, betweenVLAN route strategy (central route and distributional route), betweenVLAN access control and so on.
这么多,还这么专业,不用软件帮忙还不累晕,所有人都会用软件的,我保证我翻译的是最贴切的.呵呵!

Through uses VLAN, we may obtain very many advantage, for example enhancement management efficiency; Control broadcast data; Enhancement network security; Reduces the stand the migration and the change expenses and so on.In aspects and so on use band width, flexibility, performance, virtual local area network (VLAN) all demonstrates the very big superiority.The virtual local area network use can conveniently carry on work and so on user increase, deletion, migration, enhances the network management the efficiency.But because each main network equipment production manufacturer facilitates in the virtual local area network technology incompletely same, even their system all incompatible, perhaps very many users are attracted by the VLAN technology multitudinous merits, but also is made by this kind of chaos non-is from.Therefore, the electricity and electronic Engineer association (IEEE) passed a series of related VLAN standard, to a great extent promotion VLAN development, this article also introduced the related agreement and the standard.The VLAN exchange technology is based on OSI reference model second, but must realize VLAN to correspond must use the third equipment, if the router or has the route function switchboard.In the network development initial period, in the network only then 10%~20% information disseminate between VLAN, but along with the multimedia technologies in the network the application rapid popularization, between VLAN the information transmission capacity increased many times,if between the VLAN correspondence question solves not not well, will be serious affects the network the use and the security.Because the route has the repeater speed slowly, the price expensive and so on the shortcomings, therefore three exchange technologies arise at the historic moment.Three exchange technologies are the technologies which the route and the exchange combines, in the VLAN correspondence and the management, you can discover three switchboards will have the performance-to-price ratio compared to the router also more effective.

Key word: Virtual local area network, VLAN, route, exchange, broadcast territory

Finally proposed the VLAN technology in the enterprise network whole solution.Including: VLAN subnet division, VLAN ID plan, between VLAN route strategy (central route and distributional route), between VLAN access control and so on.
