This article presents the design and pilot implementation of a suite of intelligent methods, algorithms, and tools for federating heterogeneous experimental platforms (domains) toward a holistic Future Internet experimentation ecosystem. The proposed framework developed within the NOVI research and experimentation European collaborative effort, aims at providing a modular data, control, and management...
In this paper, we study the performance of all optical AND gates based on the four-wave-mixing (FWM) process, for application in the receivers of the spectral phase encoded optical code division multiple access (SPE-OCDMA) systems. For the performance analysis, the spectral domain auto-correlation function of the multiple access interference signal at the output of the optical AND gate is derived...
The Next Generation Access Networks (NGAN) are the new step forward to deliver broadband services and to facilitate the integration of different technologies. The real challenge faced by 10GEPON new standard IEEE 803.3av is to upgrade the channel capacity for both upstream and downstream channels gracefully, while maintaining the logical layer intact ensuring the coexistence with legacy 1 Gb/s (IEEE...
Passive Optical Networks (PONs) are experiencing their first evolutionary steps in order to support higher capacity. As high-bandwidth applications and services continue to emerge, it is expected that capacity upgrades for existing PON infrastructure will occur in the near future. In this paper, we address the upgrading problem of existing PONs that need to increase their capacity, in an “as-needed”...
Future metropolitan and access networks are expected to comprise heterogeneous optical and broadband wireless technologies. The growing demand of users for transparent, ubiquitous access to diverse communication services poses several challenges. We envision a future metro-access architecture that comprises optical burst switching networks that feed Ethernet passive optical networks (PON) or upcoming...
The amount of bursty Internet traffic leads to develop new architectures and technologies, such as Optical Burst Switching (OBS), to efficiently satisfy future bandwidth requirements. Burst loss probability is an important quality of service metric for OBS due to its bufferless characteristic, even more critical without wavelengths converters. So, resource assignment is an important issue to solve...
The access infrastructure of a network plays an important role in its overall performance. Next generation access networks must be able to provide high bandwidth capacity over the access medium, while ensuring a given level of quality of service (QoS). The MPCP (multipoint control protocol) is the standard access protocol which arbitrates the access to the channel in an EPON (Ethernet passive optical...
Ethernet passive optical networks (EPON) are a cost-effective solution for the bottle-neck problem in the access network. An open issue for this technology is the bandwidth allocation over the upstream channel in order to provide differentiated services, fairness and efficiency. Several algorithms for dynamic bandwidth allocation in EPON have been proposed, but very few of them address the possibilities...
Ethernet-based passive optical networks (EPON) are being considered as the best candidates for the next generation broadband access networks. Several algorithms for dynamic bandwidth allocation in EPON have been proposed, as this is an open issue that was left out of the scope of the standard IEEE 802.3ah. Very few of those works address the possibilities for an on-the-fly (immediate) distributed...
