A €1 million telecoms research project, O’SHARE, has been launched at the Science Foundation Ireland (SFI) research centre, CONNECT, in Trinity College Dublin (TCD). Led by Dr Marco Ruffini, assistant professor in optical network architectures in the School of Computer Science and Statistics, the four-year project will explore ways of improving the capacity of optical networks to cope with the surges in demand experienced at large gatherings such as concerts and sporting events. “O’SHARE is ultimately about sharing network resources to deliver better results for users,” according to Dr Ruffini. “Take the Electric Picnic, for example, when up to 50,000 people gather in a field in Co Laois. The cellular network suddenly experiences a surge in demand – up to a thousand times more than usual. The available capacity reduces dramatically and using a mobile device to access Facebook or to share a video becomes very frustrating. “All mobile-phone masts are connected to a fibre-optic backhaul network. This will be the focus of O'SHARE’s work as we explore ways of dynamically allocating resources to areas of poor connectivity. “We will also focus on multi-tenancy which allows several service providers to operate the optical access networks at the same time. This will also lead to greater competition in the market, resulting in cheaper data plans for users." Professor Linda Doyle, director of CONNECT, welcomed the launch: “The ideas in O’SHARE are cutting-edge. As the name suggests they are about cleverly sharing network resources which will lead to reduced costs while delivering the services users need.” The project, funded through the Science Foundation Ireland (SFI) Investigator Programme, will involve collaboration with several industry partners including Bell Labs and Vodafone. It will also see the recruitment of two senior researchers and two PhD students at the CONNECT Centre in TCD. “O'SHARE also plans to develop an international testbed to demonstrate Passive Optical Network virtualisation,”added Dr Ruffini. “Our testbed in Trinity will link to the ‘Bristol is Open’ programmable network developed by the University of Bristol. The plan is to demonstrate how operators can use virtualisation to control different parts of network infrastructure and offer seamless services spanning multiple network domains.”
