LIGHTNESS FP7 project

Lightness Low latency and high throughput dynamic network infrastructures for high performance datacentre interconnects

November 2012 – October 2015
FP7-318606

The main objective of the LIGHTNESS project is the design, implementation and experimental evaluation of a high-performance network infrastructure for data centres, where innovative photonic switching and transmission solutions are deployed. Harnessing the power of optics will enable data centres to effectively cope with the unprecedented demand growth to be faced in the near future, which will be driven by the increasing popularity of computing and storage server-side applications in the society. Indeed, the deployment of optical transmission systems leveraging Dense Wavelength Division Multiplexing (DWDM) allows the transmission of more than a hundred of wavelength channels operating at 10, 40, 100 Gb/s and beyond. This effectively results in “unlimited” bandwidth capacities of multiple Terabit/s per fibre link, which can be efficiently utilized through next-generation all-optical switching paradigms like Optical Circuit Switching (OCS) or Optical Packet Switching (OPS). In this context, LIGHTNESS will join efforts towards the demonstration of a high-performance all-optical hybrid data plane for data centre networks, combining both OCS and OPS equipment to implement transport services tailored to the specific applications’ throughput and latency requirements. To this goal, an OPS node suitable for intra- data centre connectivity services will be developed and prototyped during the project, together with an enhanced Top of the Rack (TOR) switch seamlessly connecting servers in each rack to the hybrid OCS/OPS inter-cluster network. As an additional achievement of LIGHTNESS, the OCS/OPS inter-cluster network will be empowered with a network control plane able to dynamically provision flexible connectivity services in the hybrid OCS/OPS data centre network. Such a control plane will also be developed and prototyped for integration in the final LIGHTNESS demo throughout the project.

EULER FP7 project

Domino Experimental UpdateLess Evolutive Routing

October 2010 – June 2014
FP7-258307

The main objective of the EULER exploratory research project is to investigate new routing paradigms so as to design, develop, and validate experimentally a distributed and dynamic routing scheme suitable for the future Internet and its evolution. The resulting routing scheme(s) is/are intended to address the fundamental limits of current stretch-1 shortest-path routing in terms of routing table scalability but also topology and policy dynamics (perform efficiently under dynamic network conditions). Therefore, this project will investigate trade-offs between routing table size (to enhance scalability), routing scheme stretch (to ensure routing quality) and communication cost (to efficiently and timely react to various failures). The project will develop appropriate tools to evaluate the performance of the proposed routing schemes on large-scale topologies (order of 10k nodes). Prototype of the routing protocols as well as their functional validation and performance benchmarking on the iLAB experimental facility and/or virtual experimental facilities such as PlanetLab/OneLab will allow validating under realistic conditions the overall behaviour of the proposed routing schemes.

DOMINO leverages the capacities of ultra high dynamic multi-layer optical networks to decrease the ICTs carbon footprint, and relies on five innovative concepts: a thorough analysis of the energetic issues in networks, including the benefits of using novel sub-wavelength switching devices and extending the energy-oriented model to multi-domain scenario; novel network planning strategies accounting for energy, cost and performance metrics; specialised dynamic routing algorithms where multiple constraints such as energy consumption, resource utilisation, and signal quality are optimised; energy-oriented operations and protocols in the network control plane to support the designed strategies and algorithms; dedicated techno-economic studies to evaluate the overall impact the novel concepts have on current network infrastructure and provide a possible migration roadmap.

COST IC804

Cost804 Energy efficiency in large scale distributed systems

23 January 2009 – 4 May 2013
ICT Action IC0804

This COST Action will propose realistic energy-efficient alternate solutions to share IT distributed resources. While much effort is nowadays put into hardware specific solutions to lower energy consumptions, the need for a complementary approach is necessary at the distributed system level, i.e. middleware, network and applications. The Action will characterize the energy consumption and energy efficiencies of distributed applications. Then based on the current hardware adaptation possibilities and innovative algorithms it will propose adaptive and alternative approaches taking into account the energy saving dimension of the problem. The Action will characterize the trade-off between energy savings and functional and non-functional parameters, including the economic dimension.

Leveraging all results obtained in phase 1, NOBEL phase 2 will consider the medium-term, long-term and extended long-term scenarios, focusing in particular on the last two, and will face with two major challenges. The first is the evolution of the data plane technology in order to reach an ‘optimum techno-economic balance’ between optical/electrical and circuit/packet routing and switching. The second is the evolution of the network control plane towards an unified control plane that is able of improving the seamless end-to-end network service capabilities in a flexible and scalable way. Moreover, NOBEL phase 2 will consider the opportunity deriving from the convergence of fixed and mobile services, analysing its impact on the metro and core parts of the network. To achieve the overall goals of NOBEL phase 2, the following main objectives were identified.

LION IST project

Lion Layers Interworking in Optical Networks

January 2000 – March 2003
IST-1999-11342

LION aims at giving answers to Network Operators (N.O.) about interoperability of client transport networks (e.g. ATM, SDH, IP-based) over an optical server one recommended as Optical Transport Network (OTN). In particular, the major target is to design and test over a testbed a multi-layer resilient network in a multi-domain environment. First the N.O. requirements will be defined for envisaged multi-layer network scenarios. Cost-effective integrated resilience strategies will be investigated supported by planning evaluations. The ITU-T functional modelling will be adopted to define first the OA&M and management requirements and then specifications for interfaces between network clients and OTN and between OTN domains. An “umbrella” management architecture that enables integration of TMN, WBEM, and SNMP will be designed to allow N.O. to manage the network as a whole. The above requirements and specifications will be translated into systems and sub-systems implementation to test in a testbed.

DAVID IST project

July 2000 – October 2003

Main objective is to propose a Packet-over-WDM network solution, including traffic properties and management, based on optical packets and asynchronous transmission over metro and backbone distances. The project will capitalise on both optics and electronics to find out the optimum combination to reach multi-Tb/s capacity. To cope with the on-going convergence in the transport of voice, data and multimedia applications, the project will also define several classes of service, adapted to optical layer specifics. On the metro side, the project will consider a buffer-less network using a medium access control protocol. The backbone will be based on 10 Tb/s multi-layer (wavelength and packet) opto-electronic medium access control protocol with opto-electronic packet routers, incorporating core and edge functions. Finally, the project will demonstrate highly integrated optical and electronic devices, included in a sub-equipped experimental platform.
