Technically Advanced Data Network Backup Switches
Abstract: Backup switches allow the users the capability of sharing devices or networks connected to the COMMON port/s among devices or networks connected to the (A, B, C, etc.) lettered or (1, 2, 3, etc.) numbered ports. Network switch designs and capabilities have changed significantly since the dawn of the computer age. This white paper delineates and clarifies some of the capabilities of the network switches on the market today.
Introduction: Network switches have come a long way since they were simply used to select either printer A or B for that report coming from a particular computer. Today's switches can still have simple designs and functions; however, new demands for high-speed capability, high reliability factors, and sophisticated control methods have developed a market for technically advanced network backup switches.
1. Today's Switch Requirements
Let's start at the beginning. The significant number of choices that need to be made to determine the exact switch to meet the user's requirements is an indication of the growing complexity of today's data network backup switches.
Switches are available with any number of positions, including secure off-line positions. The switches can have letters, A, B, C, etc., or numbered positions. Connect and Disconnect, On-Line and Off-Line, Normal and Loopback, and Normal and Crossover positions are also offered.
