The benefits of Creating VLAN
VLAN's enable the logical grouping and of end stations that are physically dispersed through a network. When users on a VLAN move to a new physical location but continue to perform the same job function, the end-stations of those users do not need to be reconfigured. Similarly, if users change their job function, they need not physically move: changing the VLAN membership of the end-stations to that of the new team makes the users' end-stations local to the resources of the new team. Since broadcasts frames are targeted and processed by all devices that create smaller domains to reduce overhead and limit resource utilization. Only those workstations in need of receiving specific broadcast or multicast traffic can exist on the domain, preventing other devices from receiving unnecessary traffic. The use of VLANs to create broadcast domains also eliminates the need for routers to handle this function, permitting operation at lower latencies compared to routers under heavy load. VLAN's extends beyond conventional or single LAN's to form a group of LAN's. A VLAN can be created to provide groups of users who will be transmitting data among themselves at high volume, reducing the impact on all other workstations. These user workstations do not have to be physically moved or located near one another, since the workgroup is virtual environment and created within the switching software. Of course, some shared devices such as printers or scanners require physical access, and their placement may pose a challenge if workgroup clients are located in different buildings.
The breakdown of different broadcast domains
Throughout the duration of the company's growth and as the networks begin to expand in order to alleviate collision domains in the VLAN network. An implement of essentially breaking down or dividing the networks domains will enhance security and the different segments of the OSI network will also be broken down by the function of the Marketing group. Thus the engineering group, operations as well as the call group will each have its' own assigned segment in a centralized environment. The segments will each have router in order to break up the collision domain so each subnet or segment can be created.
A plan to improve Security
It would be advantageous of essentially setting up the VLAN network with an implementation of adding security for the VLAN. (Virtual Local Area Network) An emphasis on splitting or dividing the network into the four various segments, can add security. Because each segment will be logically set apart from the rest through individual IP addresses, as well as separate MAC addresses. The network will have limitations on who can and can't access the network. Supervisory access will also allow IT administrators and other users a chance to operate or control each segment within their own environment i.e. marketing, call center, and engineering. It will provide blockades to those of who have the qualifications to access each segment.
The type of VLAN membership and the value of that choice over other options
When you assign or configure VLAN it is required to route or assign it using a number ID,
