SATA Link Layer
Objectives
This chapter will cover the Link layer functions that
transmit and receive frames;
transmit primitives based on control signals from the Transport layer;
receive primitives from the Physical layer, which are converted to control signals to the Transport
layer.
5.1 Link Layer Responsibilities
Figure 5.1 shows the key elements of the Link layer and outlines the major focal points of this section.
5.1.1 Frame Transmission Topics
When requested by the Transport layer to transmit a frame, the Link layer provides the following services:
1. Negotiates with its peer Link layer to transmit a frame; resolve ...
