One of the important layers is the data link layer. The two main functions of the data link layer are data link control and media access control. The first data link control deals with the design and procedures for communication between two adjacent nodes: node-to-node communication. Important responsibilities of data link layer are flow control and error control. The authors are using evaluating various ARQs on the basis of efficiency. One parameter that has effect on efficiency is Bit Error Rate (BER). They are changing BER for selective reject and for various window sizes trying to figure out optimum value of window size for range of BER.
