The immense growth of the Internet which is accompanied by the emergence of new communication technologies, applications, and devices, results in the evolution from voice-centric toward data-centric optical networks. In this paper we overview some of the trends in optical packet networking and identify several related research problems. Our particular focus is on the network layer aspects of future...
100 Gb Ethernet is foreseen by 2014. This contribution reviews the advantages and constraints of the optical networking and discusses how they meet the 100 Gb Ethernet needs.
A novel approach to the future hybrid communication network capable to support the traffic of different kind, e.g. real time and packet traffic and wireless signal in a single transparent network is proposed. The proposed model combines different technologies as connection and connectionless networking, optical cable and wireless (microwave/ millimeter wave or optical wireless) and it is suitable...
Next generation networking (NGN) was adopted by the World Telecommunications Standarisation Assembly in October 2004 as the official ITU (International Telecommunication Union) policy for the 2005-2008 study period. The fundamental difference between NGN and today's network is the shift from current `circuit-switched' networks to `packet-based' systems such as those using Internet Protocol (IP). Here...
This post deadline contribution reports on telecommunication applications, constraints, limitations, and (dis)advantages of libers, with special focus on attenuation/amplification, chromatic dispersion, polarization mode dispersion, and fiber non-linearity. A guidance for future development is reported as well.
