Architectures Technologies and Energy Efficiency of Optical Networks

The Increasing of today\u27s Internet services as are online video gaming, video games, video conferencing and video on demand in terms of multicasting has changed the concept of the classical approach to the networks because these services requires broadband frequency for data communication. The rapid expansion of the customer network, require wide bandwidth and increasing of energy expenditures. To gain energy efficiency we propose a novel architecture. The solution of these problems is solved by using of passive optical networks which are able to transmit data simultaneously in a broadband communication by using of optical multiplexers. The important parameters on the designing of an optical telecommunication network are energy consumption and energy efficiency of the network

Next Generation Flexible and Cognitive Heterogeneous Optical Networks:Supporting the Evolution to the Future Internet

Optical networking is the cornerstone of the Future Internet as it provides the physical infrastructure of the core backbone networks. Recent developments have enabled much better quality of service/experience for the end users, enabled through the much higher capacities that can be supported. Furthermore, optical networking developments facilitate the reduction of complexity of operations at the IP layer and therefore reduce the latency of the connections and the expenditures to deploy and operate the networks. New research directions in optical networking promise to further advance the capabilities of the Future Internet. In this book chapter, we highlight the latest activities of the optical networking community and in particular what has been the focus of EU funded research. The concepts of flexible and cognitive optical networks are introduced and their key expected benefits are highlighted. The overall framework envisioned for the future cognitive flexible optical networks are introduced and recent developments are presented
