The network performance can be significantly enhanced when the network broadcast domain is segmented into separate Layer 2 broadcast domains because, if a broadcast is not well contained in a network, it may lead to collision. Virtual local area network (VLAN) is a viable technology for broadcast containment in switched networks by logical segmentation. The network virtualization leads to ease of administration, confinement of broadcast domains, reduced broadcast traffic, as well as enforcement of security policies. This paper presents the benefits of network virtualization through the implementation of VLAN. Furthermore, practical application of VLAN for logical network segmentation based on job types is presented. Moreover, the implementation of an IEEE 802.1Q trunking protocol frame-tagging mechanism which enables multiple VLANs’ traffic between devices over the trunk link is considered.
