摘　　要：随着网络规模的扩大,网络上大量的广播信息导致网络传输效率低下,为了解决这个问题,产生了虚拟局域网(VLAN)技术。虚拟局域网是在交换网络的基础上构建的可跨越不同网段、不同网络的端到端的逻辑网络。利用带三层功能的交换机,完成虚拟局域网间的通信任务,从而避免了园区网广播风暴的出现,提高交换式园区网的整体性能和安全性及可扩展性。Along with the network expansion, the massive broadcasts information causes the network transmission efficiency to below, in order to solve this problem, the virtual local area network (VLAN) technology was produced. Based on switching network, the technology of Virtual Local Area Network (VLAN) is a logical subnet, which spans different network. Using the switchboards with three functions, completes the correspondence duty between the Virtual Local Area Network. It can avoid the network broadcast storm in order to improve the performance, security, expansibility of whole campus network.
