基于OPNET建模器的无线网络VLAN性能评估与增强
Performance evaluation and enhancement of VLAN via wireless networks using OPNET modeler
摘要：
VLAN是一种逻辑连接，它允许主机在同一个广播域中组合在一起，这样数据包就只能传送到组合到同一个VLAN的端口。通过VLAN网络的特性，可以提高无线网络的性能，节省带宽。此外，VLAN的实施通过减少接收交换机广播的帧副本的主机数量，从而使主机在单独的VLAN上保存关键数据，从而大大提高了无线网络的安全性。本文通过无线网络对无线网络和VLAN进行了比较。建议的网络进行评估的延迟和平均吞吐量使用Web浏览应用程序和文件传输在繁忙的交通。使用OPNET 14.5建模器进行了仿真，结果表明，通过无线网络使用VLAN通过减少流量，从而最大限度地减少延迟时间，从而提高了性能。此外，VLAN的实现降低了网络吞吐量，因为接收和发送的流量与吞吐量呈正相关。最后，我们研究了使用adhoc路由协议，如AODV，DSR，OLSR，TORA和GPR，以提高无线VLAN网络的性能。
英文摘要：
A VLAN is a logical connection that allows hosts to be grouped together in the same broadcast domain, so that packets are delivered only to ports that are combined to the same VLAN. We can improve wireless network performance and save bandwidth through the characteristic VLAN network. In addition, the implementation of VLAN greatly improves wireless network security by reducing the number of hosts receiving copies of frames broadcast by switches, thus keeping hosts holding critical data on a separate VLAN. In this paper we compare wireless network with VLAN via wireless network. The proposed network is evaluated within terms of delay and average throughput using web browsing applications and file transfer in heavy traffic. The simulation was carried out using OPNET 14.5 modeler and the results show that the use of VLAN via wireless network improved performance by reducing traffic resulting in a minimized delay time. Furthermore, VLAN implementation reduces network throughput because the traffic received and transmitted has a positive relationship with throughput. Eventually, we investigated the use of adhoc routing protocols such as AODV, DSR, OLSR, TORA and GPR to improve the performance of wireless VLAN networks.
