The network, internetwork and higher layers vary widely depending upon situation and application. The data link layer is the one most in need of study and understanding. This is the layer concerned with the actual transmission of data, and its reliable receipt. Three chapters relate to the basic concepts of the data link layer, an introduction, error detection and correction, and controls. The remainder of the book concentrates on the specific protocols; BSC, HDLC, LAPB, LAPD, LAN protocols, LLC and so forth. Two chapters are of particular interest to the online community, covering asynchronous file transfer protocols (X modem and descendents, Kermit, and others) and LAPM (Link Access Protocol for Microcomputers or V.42). Frame relay and Internet protocols are touched on. This work deals with the concepts rather than implementations. The actual programming of specific protocols will require additional detail. However, for an understanding of the options at this layer in the stack, this is a good starting source. copyright Robert M.
