Combining Optics and SDN In next Generation data centre Networks (COSIGN)
Date du début: 1 janv. 2014, Date de fin: 31 déc. 2016 PROJET  TERMINÉ 

The role of Data Centres (DCs) is vital for the Future Internet. However, DC infrastructures are already stressed by data volumes and service provisioning and consumption trends. Emerging demands cannot be addressed by today's DCs and call for a massive redesign or even transformation of DC architectures.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
