Review on Multiplexing Techniques in Bandwidth Utilization
نویسندگان
چکیده
Multiplexing is a method by which multiple analog message signals or digital data streams, coming from different sources are combined into one signal over a shared medium. In this paper, we present an overview of different multiplexing techniques in bandwidth utilization. We focus on the three well-known multiplexing technique used in bandwidth utilization which are Frequency-Division Multiplexing (FDM), Wavelength-Division Multiplexing (WDM) and Time-Division Multiplexing (TDM). We mainly discuss the multiplexing technique, features and structures. This paper also briefly discuss an applications involved in these multiplexing techniques and the advantages and disadvantages of these three multiplexing techniques. At the end of this paper, we summarize and make a comparison between FDM, WDM and TDM.

A Bandwidth Allocation Scheme in Optical TDM Network
Wavelength Routing (WR) and Optical Burst Switching (OBS) are two optical network techniques that have received enormous attention over the last decade. However, the two techniques are plagued with many problems. The main concern with WR is the inefficient bandwidth utilization. On the other hand, the problem with OBS is resource contention and burst dropping. In this paper, we propose a new sc...

This document contains recommendations of maximum tolerable delays to be added by methods which improve bandwidth utilization through compression, multiplexing, and tunneling over a network path. Recommendations are presented only for real-time network services for which such bandwidth optimization techniques are applicable (i.e., services with low payload size to header size ratio).
