An all-optical network architecture

Abstract

A novel photonic network, MATRIX (for Multiwavelength All-optical TRansparent Information exchange), is proposed in this paper. The all-optical multihop network supports wavelength continuity and provides a very high network capacity. Spatial reuse of wavelengths as well as the multiplicity of fibers in optical fiber cables are exploited and enable the interconnection of N 2 network nodes with merely N wavelengths. The node structure is simple since neither tunable devices nor wavelength converters are required. Packets are routed through the network by photonic fast packet switching as well as by wavelength and experience a maximum hop number of two. Multiple optical paths between any pair of nodes provide a good network survivability.

A Comparative Survey on Optical Burst Switched Network Simulators

“…Also, OPNET accelerates the R&D process for analyzing and designing network also catering optical buffering (implementation of FDLs), wavelength conversion and different assembly algorithms. This simulator is used in [12], [13] and [14].…”

Performance Analysis of Serial Attachment Modified Prime Sequence Code with Multi-layer/Parallel Decoder Architecture

“…We define the Generator Polynominal G P L (x) of the original Modified Prime Code Sequence for a given prime number L as (1) J 0 (L), J 1 (L), …, J P L -1 (L) are the positions of bit "1" in the Modified Prime Code Sequence P L , and are determined by J k (m, n, k, L), where k = 0, 1, 2, …, P L -1 for kth binary "1" in C m,n where J k (m, n, k, L) and C m,n are defined in [14].…”

“…Code division multiple access (CDMA) Techniques have been proposed for the fiber-optic communication networks by various authors recently [1][2][3][4][5]. Using prime code as the spreading code for all optical CDMA system has been wildly studied in the past few years [6][7][8][9].…”
