GEYSERS: a novel architecture for virtualization and co-provisioning of dynamic optical networks and IT services Ghent University
Programmable multi-granular optical networks: requirements and architecture Ghent University
This paper presents a programmable multi-granular optical cross connect (MG-OXC) and network architecture deployable in multi-service and multi-provider networks. The concept of programmable MG-OXC is introduced to provide a way of utilizing multiple switching/transport granularities to efficiently support the emerging traffic demands in both core and metro networks. For this reason, the supported bandwidth granularities include full lambdas, ...
A network control plane architecture for on-demand co-provisioning of optical network and IT services Ghent University
Why Optical Packet Switching failed and can Elastic Optical Networks take its place? Interuniversity Microelectronics Centre Ghent University
In this special issue devoted to the memory of Prof. Fabio Neri we would like to look back at the time of the international research projects where some of us collaborated with him. On the basis of our personal experience of the time and the current viewpoint, we will discuss why Optical Packet Switching (OPS) is a technology that never came to market in spite of the great amount of research that was devoted to it. Then we will explore how ...
Trade-off between end-to-end reliable and cost-effective TDMA/WDM passive optical networks Ghent University
Hybrid TDMA/VVDM (TWDM) Passive Optical Network (PON) is a promising candidate for Next-Generation PON (NG-PON) solutions. We propose end-to end reliable architectures for business users and a cost-effective network for residential users. We evaluate the proposed reliable architectures in terms of protection coverage, connection availability, impact of failure (i.e. to avoid a huge number of end users being affected by any single failure) and ...
