—The exponential growth of Internet traffic gives no respite to the telecommunications industry , and is visibly shortening the life-cycle of the technologies used for core networking. To cope with the traffic demand , the industry has primarily fo-cused on the evolution of the data and control planes , and has rapidly made progress in both subjects.(More)
Network coding has been recently proposed as a proactive network protection scheme. Its main objective is to improve the resilience of wired networks against link failures in a proactive manner, while simultaneously providing network resource savings (IP bandwidth, optical wavelengths) compared to traditional protection schemes. Warned by the potential(More)
—The recent advances in optical technologies pave the way to the deployment of high-bandwidth services. As reliability becomes a mandatory requirement for some of these services, network providers must endow their networks with resilience capabilities. In recent years, network coding protection (NCP) has emerged as a tentative solution aiming at enabling(More)
Optical technologies are the foundations supporting the current telecommunication network backbones due to the high speed transmissions achieved in fiber optical networks. Traditional optical networks consist of a fixed 50 GHz grid, resulting in a low optical spectrum (OS) utilization, specifically with transmission rates above 100 Gbps. This issue is(More)
Hybrid Software-Defined Networks (SDNs) are growing at a remarkable speed, so network administrators need to deal with the configuration of a plethora of devices including OpenFlow elements, traditional equipment, and nodes supporting both OpenFlow and traditional features. The OpenFlow Management and Configuration Protocol (OF-CONFIG) is positioned as a(More)
Despite the increasing number of mobile heterogeneous network elements (NEs) interconnected through the Internet, all of them setting the foundations for an agile IoT development, many issues remain still unsolved. The scalability of the current host-oriented Internet model is one of these problems. In this paper, we present a novel service-oriented(More)
