For processing large amounts of data, management and switching of communications may contribute significantly to energy consumption and cloud computing seems to be an alternative to office-based computing. ABSTRACT | Network-based cloud computing is rapidly expanding as an alternative to conventional office-based computing. As cloud computing becomes more(More)
—In this paper, we present a new method for the estimation of blocking probabilities in bufferless optical burst or packet switched networks. In such networks, deflection routing is used to reduce blocking probability. However, it requires certain wastage due to trunk reservation that must be used to avoid instability. We provide a wide range of simulation(More)
ntil recently, research and development in the area of communications networks has been mainly targeted at functionality and performance. Only for battery-driven devices, such as mobile handsets and wireless sensors, was energy efficiency a significant consideration. This has changed significantly with the massive use of communications in public,(More)
—We develop a new analytical model for the estimation of blocking probabilities in OPS and OBS networks. The model is used to analyze the performance of a new deflection method that uses multiple wavelength channel reservation thresholds, and gives network designers greater control over the performance of the network. The accuracy of the analytical model is(More)
he Internet has become an integral component of the economies of all developed and developing nations. The virtual cycle of improvements in telecommunications supporting economic growth, which, in turn, supports growth in telecommunications infrastructure has served many nations very well. However, this cycle cannot continue without end because all(More)
With the abrupt advancement in technology, every business organization aspires to migrate to cloud. The technology of cloud computing makes use of the huge data centers that present multiple issues such as extensive amounts of energy consumption, dissipation of lots of heat and methane, carbon dioxide, etc. like deadly greenhouse compounds and gases. In(More)
Optical burst switching (OBS) technology has been proposed as a promising switching solution for the terabit bandwidth utilization in next-generation wavelength division multiplexing (WDM) optical transport network. Control architecture and Contention resolution are the main issues faced by the Optical Burst Switching networks. This paper only taking care(More)
Energy efficiency has become an increasingly important aspect of designing access networks, due to both increased concerns for global warming and increased network costs related to energy consumption. Comparing access, metro, and core, the access constitutes a substantial part of the per subscriber network energy consumption and is regarded as the(More)
