1、 毕毕 业业 论论 文文 论文题目:论文题目: 虚拟局域网技术虚拟局域网技术 内 容 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。 随着网络技术日新月异的发展,现代局域网已进入高速交换时代。以交换 技术为基础产生的 VLAN 技术是一种新的热门技术,目前正在得到越来越广泛 的应用从
2、某种角度讲,VLAN 技术己经成为现代大型局域网建设、管理和应用 不可缺少的技术。研究 VLAN 技术的应用,对于网络的建设、管理和应用具有 十分重要的意义。 关键词关键词:虚拟局域网 技术 划分 应用 Abstract The virtual local area network (VLAN), is one kind through is not physics divides local area network in equipment logic each one webpage to realize the hypothesized work teams emerging tech
3、nology, in function and operation and traditional LAN basic same.The virtual local area network technology is one of present network most popular technologies, also is exchanges in the network one of most important technical, its appearance is and the local area network exchange technology developme
4、nt cannot separate.The VLAN appearance has broken traditional network many inherent ideas, causes the network architecture to become is nimble, is convenient. With the rapid development of network technology, modern high-speed local area network has entered the era of exchange. In exchange for techn
5、ology-based VLAN generated by the new technology is a hot technology, is being increasingly wide range of applications from a certain point say, VLAN technology has been become a modern large-scale local area network construction, management and application of essential technologies. VLAN technology
