In networking and communications, the formats, codes and procedures for transmitting a unit of data (frame, packet) from one node to another. Known as a "layer 2 protocol," the data link protocol ...

A case can be made for using an automated solution to test and troubleshoot the data link layer of these critical physical connections. But first the links and link types should be examined.

Networking author Howard C. Berkowitz provides tips on avoiding and fixing data link network failures in Part 3 of his series.
