The Network Access Layer is the lowest of the four hierarchal abstraction layers. Its primary use is to provide specifications for how data moves through the network. This layer allows for the capability of the system to deliver data to the other devices on an attached network. The Network Access Layer protocols must have details of underlying networks in order to format the transmitted data correctly whilst maintaining compliance within constraints. The TCP/IP Network Access Layer is all encompassing and carries out functions of other layers below it.
The Network Access Layer can often be overlooked, especially in relation to the other layers involved such as IP, TCP, UPD etc. In line with the development of new developments in the hardware industry, protocols must also be continually developed in order to make use of new hardware types. As a result, there are many, many network protocols.
Functions carried out by the Network Access Layer include the inclusion of IP datagrams as well as the location of IP addresses in relation to the fixed IP location. It is believed by many that one of universal addressing scheme used in the TCP/IP is one of its key strengths. It is essential that the IP address is transformed into an appropriate address given the network by which the datagram will be transmitted.
