Network Performance Through Virtual Local Area Network (VLAN) Implementation & Enforcement On Network Security For Enterprise

The aim of this paper was to enhance an enterprise network performance through VLAN implementation by simulating an existing LAN and rectify LAN using VLAN at, in two different scenarios. To rectify the drawbacks of existing enterprise network using virtual local area network. To simulate and compare the new (VLAN) and existing (NO_VLAN) enterprise network performance Virtual LAN technology can also be used to mitigate vulnerability surface for hackers by reducing the traffic request to servers, network visualization leads to ease of administration. There were more benefits of network virtualization through the implementation of VLAN. Thus, VLANs improved bandwidth utilization, power, speed and security. However, nowadays the high-speed network makes people to sense that network is a much more powerful tool to enhance in any business enterprise and make the company running more efficient. The main purpose of the network ability in the universities is to support learning, teaching, research and sharing of information. Unfortunately, even though the capacity of the bandwidth considered to be sufficient, the network can appear slow and inconsistent due to some factors like: the poor network design, the number of devices on the network, local network protocols (MAC Protocol) and misuse of the bandwidth by accessing to bandwidth hungry websites and applications (Dhurgham , 2018).
