Multi-layer Traffic Engineering in Data-centric Optical Networks Illustration of concepts and benefits

چکیده
Intelligent Optical Networks (IONs) allow setting up or tearing down lightpaths dynamically. The logical topology in multi-layer networks (such as IP-over-OTN scenarios) is supported by these lightpaths, and thus dynamically configurable. Consequently, traffic engineering functionality is extended with cross-layer capabilities, leading to multi-layer traffic engineering (MTE). This paper explains the concepts behind MTE, how typical MTE strategies function and what issues arise while developing such strategies. The benefits are illustrated by means of the results from two case studies.

The Application of Multi-Layer Artificial Neural Networks in Speckle Reduction (Methodology)
Optical Coherence Tomography (OCT) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. An inherent characteristic of coherent imaging is the presence of speckle noise. In this study we use a new ensemble framework which is a combination of several Multi-Layer Perceptron (MLP) neural networks to denoise OCT images. The noise is...
متن کاملA Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...
متن کاملData-centric optical networks and their survivability
The explosive growth of data-traffic, for example due to the popularity of the Internet, poses important emerging network requirements on today’s telecommunication networks. This paper describes how core networks will evolve to Optical Transport Networks (OTNs), which are optimised for the transport of data-traffic, resulting in a IP-directly-over-OTN paradigm. Special attention is paid to the ...
متن کاملDetecting Bot Networks Based On HTTP And TLS Traffic Analysis
Abstract— Bot networks are a serious threat to cyber security, whose destructive behavior affects network performance directly. Detecting of infected HTTP communications is a big challenge because infected HTTP connections are clearly merged with other types of HTTP traffic. Cybercriminals prefer to use the web as a communication environment to launch application layer attacks and secretly enga...
متن کاملMulti-layer Clustering Topology Design in Densely Deployed Wireless Sensor Network using Evolutionary Algorithms
Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...
