Exploring VLAN

In most networks, there are a lot of different traffic types, such as voice traffic generated from VoIP phones, video traffic from surveillance systems and telepresence equipment, and data traffic from end devices such as computers, servers, and printers. Imagine that an organization wants to segment these traffic types by implementing separate and dedicated network equipment for each type of traffic. This would mean creating three physically isolated networks to keep each traffic type apart from the other. The disadvantage of performing physical segmentation is the high cost of purchasing dedicated network equipment to build these networks.

With the evolution of the networking industry, we can create a fully converged network to allow all traffic types to use the same physical network while implementing logical segmentation of traffic using network switches. This allows for the creation of a single, well-designed physical network for voice, video, and data traffic...
