Cisco ISP Essentials (Free PDF)

The Internet economy has played a significant part in the world economy since the mid 1990s. For many years prior, the Internet was the domain of U.S. academic research and defense internetworking, and a few entrepreneurs around the world who believed that a TCP/IP-based wide-area network (WAN) would be a viable alternative to the private wire networks that businesses were using to communicate with each other. The many ISP engineers who learned their skills in that period look on those early pioneering days at the end of the 1980s and early 1990s as something special. Work was invariably hard, and technology challenges were seemingly insurmountable when compared with the relative ease of use and configuration these days. But the sense of competition was more a friendly rivalry and partnership to make the fledgling Internet a fun place to be.

This pioneering spirit, and the desire of the Internet community to make the Internet a success, has resulted in the Internet becoming the major part of our lives at the start of the 21st century. It’s now a huge commercial network, very competitive, with many players, small and large, from all over the world, heavily involved in its infrastructure. More people are taking part in the Internet every day, both end users with their first computer connecting to the World Wide Web, and new ISPs anxious to become part of a very significant growth industry. Furthermore, the few remaining countries in the world without an Internet connection are investigating connecting up and examining the advantages being networked will offer their local economies.

As the Internet has grown in our day-to-day consciousness, so have textbooks aspiring to help newcomers find the proverbial pot of gold: books ranging from beginner guides to designing web pages, to explaining what the Internet is, to describing the business process, to becoming a successful ISP. However, there has been precious little that describes the configuration concepts and tricks of the trade that ISP network engineers use in their daily lives—there is an argument which says, “We have been too busy fixing the potholes in the Internet superhighway to actually spend time writing down what we do.”
