Cosign Combining optics and SDN in next generation data centre networks

January 2014 – December 2016
FP7-619572

COSIGN proposes a new DC architecture empowered by advanced optical technologies and will demonstrate novel solutions capable of sustaining the growing resource and operational demands of next generation DC Networks. COSIGN aims to move away from today’s vendor specific, manually controlled, performance and scale limited DCs towards scalable DC solutions able to support future-proof dynamic, on demand, low-latency, energy efficient and ultra-high bandwidth DC solutions. COSIGN introduces disruptive transformations in the data plane, significant advances to the control plane and major innovations in the DC virtualization and service orchestration:

  • In the DC Data Plane, COSIGN will deliver an entirely-optical solution enabling scalable top-of-rack switches, ultra-low latency and high volume DC interconnects with high spatial dimensioning.
  • In the DC Control Plane, COSIGN will build upon and extend the Software Defined Networks (SDN) paradigm leveraging capabilities from high-performance optical technologies while developing technology agnostic protocols for software/user defined routing and control.
  • For the DC Management and Orchestration, COSIGN will implement a coherent framework for optical network and IT infrastructure abstraction, virtualization and end-to-end service orchestration.

COSIGN brings together a unique combination of skills and expertise able to deliver, for the first time, a coordinated hardware and software architecture, which will guarantee the scale and performance required for future DCs. Results will be demonstrated in challenging industrial setting, leveraging a DC validation platform from Interoute – a leading European service provider.

Pristine Programmability in RINA for European Supremacy of Virtualized Networks

January 2014 – October 2016
FP7-619305

The Internet as the global communications infrastructure has been successful in shaping the modern world by the way we access and exchange information. The Internet architecture originally designed in the 1960s has been supporting a variety of applications and offering a number of services till now but emerging applications demand better quality, programmability, resilience and protection. Any alterations to the Internet architecture have become restricted to simple incremental updates and plug-ins instead of radical changes by introducing new solutions.

RINA, the Recursive InterNetwork Architecture, is an emerging clean-slate programmable networking approach, centring on Inter-Process Communication (IPC) paradigm, which will support high scalability, multi-homing, built-in security, seamless access to real-time information and operation in dynamic environments. The heart of this networking structure is naturally formed and organised by blocks of containers called Distributed Information Facilities (DIFs) where each block has programmable functions to be attributed to as they required. A DIF is seen as an organizing structure, grouping together application processes that provide IPC services and are configured under the same policies. Virtualization is a fundamental attribute of the architecture itself. Based on the above fundamental aspect, PRISTINE intends to:

  • Design, develop and implement the innovative internals of this clean-slate architecture that include the programmable functions for: security of content and application processes, supporting QoS and congestion control in aggregated levels, providing protection and resilience, facilitating more efficient topological routing, and multi-layer management for handling configuration, performance and security.
  • Demonstrate the applicability and benefits of this approach and its built-in functions in use-cases driven by the end-users, service providers and equipment vendors in the consortium. This will ensure that the applications and tools we develop will be deployable by providers, and have a greater potential for future exploitation.

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.

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 Design and optimization of multi-layer green optical networks

January 2011 – December 2014
TEC2010-18522

The DOMINO project aims at designing novel architecture, algorithms and protocols solutions fulfilling the energy efficiency and awareness requirements of future multi-layer green optical networks. 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.

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.
