Computer Network Engineering
The need for increased traffic control in computer networking becomes more and more apparent every day as new technologies emerge. Since the advent of Kazaa, AIM, and other P2P traffic, as well as the daily eruption of new viruses and worms, control and network security becomes more of a need then ever before. Different people have different computing |
needs, and others may not have the need for certain data, where others do. That is why it is important to keep relevant data traffic where it is needed, and away from where it is not. This is where network segmentation, (sub-netting) comes into play.
Traffic is controlled between these networks with devices called routers. A router is like a traffic cop, it controls the traffic between networks by letting pertinent information in and out of one network segment where it is requested, while keeping irrelevant traffic out, and routing it to the appropriate network.
Another aspect of traffic control is Quality of Service. Quality of Service (QoS) is controlled with devices that regulate the flow of certain traffic (protocols) much like a router but with more detail and granularity. With QoS devices you can throttle, filter, and prioritize certain traffic, shaping and fine tuning your network traffic control, thus increasing the Quality of Service.
Without the proper network segmentation, all traffic would be forced to utilize the same network infrastructure for all. This is called a "Flat" network. This is not recommended for users over a certain amount, and before long, traffic jams, also known in the industry as "bottlenecks" will occur, severely slowing down your network.
With the proper network segmentation, Routing, and QoS, everyone and their needs can coexist in the same place physically, while enjoying a high performing network experience.
