“…Utilizing procedures like WDM, a hundred Gbps optical connections have been created, while electrical transmission innovations are generally confined to 40 Gbps. Optical fibers can work with electrical switches with handsets [7,8]. Optical fibers can likewise work with the exception of photoelectric change through coordinating a light emission from any info port to any yield port.…”

Data centers (DCs) have emerged as an irreplaceable and essential infrastructure to support this ever-growing trend as a result of the exponential growth of Internet services. A DC typically houses a large number of computing and storage nodes, interconnected by a network that has been specially designed, namely DC. The DCN serves as a foundation for interaction and plays a key role in the optimization of DC operations. In this paper, a brief survey of various architectures of data center network (DCN) is presented based on their switching and transmission technology. This paper also depicts a comparison of different topologies of representative data center networks with respect to several properties to highlight their advantages and disadvantages.

In the past few years, with the development of information technology and the focus on information security, many studies have gradually been aimed at data hiding technology. The embedding and extraction algorithms are mainly used by the technology to hide the data that requires secret transmission into a multimedia carrier so that the data transmission cannot be realized to achieve secure communication. Among them, reversible data hiding (RDH) is a technology for the applications that demand the secret data extraction as well as the original carrier recovery without distortion, such as remote medical diagnosis or military secret transmission. In this work, we hypothesize that the RDH performance can be enhanced by a more accurate pixel value predictor. We propose a new RDH scheme of prediction-error expansion (PEE) based on a multilayer perceptron, which is an extensively used artificial neural network in plenty of applications. The scheme utilizes the correlation between image pixel values and their adjacent pixels to obtain a well-trained multilayer perceptron so that we are capable of achieving more accurate pixel prediction results. Our data mapping method based on the three-dimensional prediction-error histogram modification uses all eight octants in the three-dimensional space for secret data embedding. The experimental results of our RDH scheme show that the embedding capacity greatly increases and the image quality is still well maintained.

<span>In this study, the low-group velocity slow-light mach-zehnder interferometer (MZI) modulator, low loss and high efficiency for two modulator substrate lithium niobate (LN) and silicon were presented and optimized at 1.55µm operating wavelength. The high power consumption of conventional modulator was the major drawback in the operation of modulators. Therefore, it was a good time for low-power modulator design and development and to compare the LN and Silicon modulator on the phase shifted using the slow-light technique by designing the full MZI modulator consisting of splitter and combiner on both substrates. The phase shift of LN is 2% compared with the silicon 0.09% and higher phase shift give better performance with low power consumption due to the change of modulating voltage of the MZI modulator for LN while the silicon depends on modulating voltage manipulating concentration of charge carrier in doped silicon.</span>
