The ever-increasing growth of the current Internet traffic volume is demanding a bandwidth which can only be satisfied by means of optical technology. However, while WDM networks will bring an unprecedented amount of available bandwidth, traffic management techniques become necessary in order to make this bandwidth readily available to the end user. In this chapter we provide an overview of tra...

Demands for networks of higher and higher capacities are increasing dramatically with the growth of the Internet and the World Wide Web. All-optical wavelength-division multiplexing (WDM) networks is the most promising candidate to fulfill the bandwidth requirement of the Broadband Integrated Services Digital Network (B-ISDN). In WDM networks, the huge bandwidth available on an optical fiber is...

The emergence of wavelength division multiplexing (WDM) technology has significantly increased the transmission capacity of a link in today's optical networks. In WDM networks, the bandwidth request of a traffic stream is usually much lower than the capacity of a wavelength. Traffic grooming can aggregate low-rate connections onto high-capacity optical fibers to make an efficient use of the ban...

With the proliferation of the world-wide-web (WWW), current local and wide area networks can hardly cope with the huge demand for network bandwidth. As a result, there is a world-wide effort in upgrading current networks with highcapacity fiber-optic links that can potentially deliver Tera-bits/sec bandwidth. The Wavelength-Division-Multiplexing (WDM) is an effective technique for utilizing the...

Recent development in optical networking employing wavelength-division-multiplexing (WDM) fulfills the high bandwidth demand applications. Failure of such networks, leads to enormous data and revenue loss. Design a low cost survivable WDM network is always an interesting and difficult process. In this paper we present link-path model for capacity allocation and calculate blocking probability in...

The WDM network is an optical network to employ the wavelength division multiplex WDM technology. This technology provides transmission of data on different optical wavelengths through the same optical fiber. We will concentrate on WDM network only, where each wavelength corresponds to a data communication channel. Moreover, we deal with all-optical networks. In these networks, the optical sign...

Abstract. We propose a framework to analyze and compare wavelength division multiplexed (WDM) switching networks qualitatively and quantitatively. The framework not only help analyze and compare the complexity of WDM switching networks, but also explain interesting properties of different designs. Then, several important problems arising from this idea are addressed, and complexity bounds are d...

This paper describes researches concerning the use of Wavelength-Division Multiplexing (WDM) techniques over Polymer Optical Fibres (POFs) links for Residential Networks applications. It is reported the development of a 2-channel WDM Multiplexer/Demultiplexer (MUX/DEMUX) device based on a commercially available dichroic beam-splitter operating in the visible spectra. It describes the use of the...

In this paper, we study the effect of the round trip propagation delay on performance measures of WDM networks and adopt a dynamic policy and a synchronous transmission procedure to access data channels. Also we propose a new control architecture for WDM star-coupled networks, to overcome the electronic processing bottleneck that the single control channel architecture introduces. Key-Words: Wa...

In this article, we first discuss QoS metrics of the data networks, followed by raising the challenging problems for the nextgeneration Internet with high-performance and high-quality. We then discuss how the WDM technology can be incorporated for resolving those problems. Several research issues for the IP over WDM networks are also identified. key words: Internet, IP (Internet Protocol), TCP ...
