The Internet carries certain critical data and information which needs to be delivered to the receiver at all cost. The primary factor hindering the flow of traffic is the network congestion. Also another issue in data communication is the speed of data transmission. 56 kbps was the fastest speed in the late 1960s but today speeds of 112 Mbps are achieved for household usage.
