Segmentação virtual de redes de computadores

Abstract

This dissertation hás the objective to study and analyze the traffic in computer networks using virtual segmentation, or more specifically, Virtual Local Area Network (VLAN). The technique of network segmentation is a subject little explored in literature, merely, in general, small sections of books, some certification guides and equipment manuals. The material produced by this paper presents a synthesis and examples of VLAN. The software OPNET IT Guru Academic Edition was used to analyze the traffic data from switches utilizing VLANs. This tool enables the creation of scenarios for simulation in computer networks. For the virtual segmentation of networks was proposed solution VLAN Trunking Protocol (VTP). This solution allows the spanning of VLANs across multiple switches and also the configuration of more than one virtual network for each equipment. Computer networks utilizing virtual segmentation were compared. As from the use of VLANs, the total network traffic had significantly reduction, come near, in some situations, to 70%.
