Evaluación del protocolo 802.1Q en la implementación de VLANS en entornos wireless mediante la aplicación de software libre

Abstract

IEEE 802.1Q protocol was applied in the implementation of virtual local area networks – VLAN in wireless environments by using specialized hardware configured with free software. The evaluation of the protocol was a useful tool to identify the procedure applied by bridging architecture towards the frames arriving to a device that operates on Data Link layer – Layer 2. The procedure performed two roles: first, to redirect the coming frames to the same LAN that can be virtual or different. Second, it rejects frames that do not adjust to the configuration parameters. Once a wireless router is provided with a freely distributable firmware, it becomes a device with greater flexibility and adaptability in its configuration and operation. The use of fully configurable devices in data networks and communication enabled to raise levels of performance and safety. In order to verify the application of the protocol IEEE 802.1Q, a prototype wireless network with multiple virtual LAN was implemented. Connectivity test conducted, made possible to check and validate the implementation of the protocol in wireless environments. Finally, the proposal was presented as an alternative solution to the problem of segmentation of physical network into logical networks in wireless environments. It is recommended to apply the IEEE 802.1Q protocol in the segmentation of physical networks in wireless environments for improving the level of traffic efficiency on data networks.
