Duty Cycle Division Multiplexing (DCDM) has been shown to be able to improve utilization of the optical bandwidth. However, the challenge arises on its signal recovery at the receiver ends. Decision making protocol plays an important role to determine the correctness of its regenerated data. Previous approach regenerate inaccurate data due to its assumption that all received signals are valid. Thus,...
This paper aims to study the design issues of a future switch and to identify the bottlenecks of the state-of-the-art technology to support the future traffic and service demand. The future switch should perform high speed switching, eliminate the implementation of buffers, transparent packet format and allows multiple user access. Thus, the development of a heuristic approach that handles multi protocol...
This paper is aimed to evaluate the WDM technique for an optical switch in the optical access network. The design and performance parameters consist of the inbound offered load, number of wavelengths, switch size and normalized throughput. Also, it explores the wavelength domain to demonstrate the possibility of appropriation wavelength assignment in enhancing the network throughput. The simulation...
In this paper, authors compared the performance of the MPOS routing algorithm against conventional packet schemes using multimedia traffic. The MPOS routing segregates the different types of multimedia traffic into dedicated classes/priorities and assigns a light path for each of them. Improved network performance has been observed by the MPOS technique at high traffic load.
This work presents a novel routing protocol based MPOS (B.H.L. Lee et al., 2006), which is used in the construction of the multiprotocol switch for multimedia traffic. The MPOS routing segregates the different types of multimedia traffic into dedicated classes/priorities and assigns a light path for each of them. Experimental results of the MPOS routing optimize cost of the maximum end-to-end delay...
We demonstrate the use of an auto regressive moving average (ARMA) optical lattice alter in compensating polarization mode dispersion (PMD) by minimizing the differential group delay (DGD) within a given frequency range. A numerical simulation was performed for a 4th order ARMA filter to compare the DGD values before and after filtering. Also, a quasi-analytical simulation was performed to estimate...
This paper investigates the performance of a step and linear shared buffering strategy for wavelength routed optical network using an object oriented programming technique (OOP). In particular we relate the entire study with the wavelength routed switching matrix architecture by the used of an arrayed waveguide grating matrix (AWG), multiplexer (MUX), demultiplexer (DEMUX) and semiconductor optical...
