Data Link Layer: The data link layer functions mainly to detect and correct errors made in the physical layer and to pack data bytes into frames to transmit to the network layer and packet synchronization.This can range from electric circuits and cables to voltages and Wi-Fi signals – anything which acts as the immediate interface for the transmission of raw data. Physical Layer: The first and lowest layer is concerning the physical and electrical link between networks.In order to properly visualize the process of network traffic, it is described using the OSI Model (Open Systems Interconnection Model) - an abstract conceptualization of the 7 layers of network communication published in 1984 by the International Organization for Standardization (ISO). Latency-sensitive traffic risks slower data retrieval as the ability of data transfer across the network is cut down drastically.Non-real-time traffic refers to bandwidth consumption mainly during public working hours – such as HTTP, FTP, and e-mail.Interactive traffic where bandwidth prioritization takes place - resulting in slower responses without web and application traffic limitations in place.

Heavy traffic where high amounts of bandwidth are utilized - these would be extremely active and constant network traffic routes.There are different categories into which these traffic levels can be placed: Different activities and behavior will result in different types of network traffic activity. Network traffic is the traveling of data through a network. This data movement causes the phenomena of network traffic. This unsurmountable surge of data traverses through cyberspace by breaking up into smaller “data packets” for the sake of transmission, then reassembles itself at its destination. Today everything is connected through the internet – billions of pieces of data are constantly being transferred to and from our phones, laptops, smartwatches, and every other device connected to a network.
