What do you mean by edge coloring of a graph?

What is edge chromatic number?

The edge chromatic number, sometimes also called the chromatic index, of a graph is fewest number of colors necessary to color each edge of. such that no two edges incident on the same vertex have the same color. In other words, it is the number of distinct colors in a minimum edge coloring.
