  • ATM is a packet-switched technology based on a 53-byte packet called a cell. Each cell is divided into a 5-byte header and a 48-byte payload. The short, fixed length cell reduces delay and jitter, allowing time sensitive information such as voice and video to be transported along with data. There are various transmission media and rates available with bandwidth measured in megabits to gigabits.

  • For many years I have been a consultant for different companies and have written books on switch and router configurations and troubleshooting. During my years as a consultant I have had to either install, administer, or troubleshoot switching problems and configurations for switches without a good handbook. I have constantly gone through bookstores looking for a book on Cisco switch troubleshooting and configurations that didn’t deal with a Cisco curriculum. Guess what? I couldn’t find one!

  • Enterprise customers have in the past relied heavily upon traditional WAN/MAN services for their connectivity requirements. Layer 2 circuits based on TDM, Frame Relay, ATM, and SONET have formed the mainstay of most low-speed WAN services. More recently, high-speed MAN solutions have been delivered directly over Layer 1 optical circuits, SONET, or through the implementation of point-to-point or point-to-multipoint Ethernet services delivered over one of these two technologies.
