Utilizing channel characteristics to improve inverse multiplexing efficiency over time division multiplexed communication links

Author

Abstract

"The information industry is currently growing to a point where the traditional ‘single link’ telecommunication solutions that powered information exchange are becoming insufficient. ISDN and BONDed T1, at 128 Kb/s and 1.544 Mb/s respectively, no longer provide enough bandwidth to handle most companies’ daily activities. The next step up in traditional tariffed service is a T3, but at 45 Mb/s the T3 is prohibitively expensive for all but the largest user bases.[j1]

This thesis studies one class of solutions for this problem: bandwidth aggregation or Inverse Multiplexing. Combining multiple inexpensive communication channels to provide a larger virtual link is not a new theory but one that is starting to see more wide- scale deployment due to favorable changes in the economics of bandwidth. The scope of this research is limited to Time Division Multiplexed systems utilizing T1 style links. The author examines the current state of the industry, offers an analysis of why systems were deployed as they are, and considers a new, high efficiency solution.

A new Inverse Multiplexing scheme is presented, one that utilizes the characteristics of the T1 system to greatly reduce overhead and increase transmission efficiency while retaining a feature set believed to be suitable for the majority of users. A model hardware implementation as well as a software model of the system is presented, along with an analysis of performance in various operating conditions. The new system is compared to existing Inverse Multiplexing solutions with respect to implementation complexity, expense, bandwidth efficiency, required equipment, and user experience"--Abstract, page iii.
