SUNSET: Sustainable Network Infrastructure Enabling the Future Digital Society
January 2015 – December 2017
The Project SUNSET has the key objective to overcome the bottlenecks of current transport networks, providing effective network solutions for the future Digital Society and paving the way toward innovative ICT services “on the cloud”. These services will favor their sustainable utilization by nowadays’ major economic sectors, leveraging their competitiveness through next‐generation cloud services. More specifically, SUNSET proposes a novel network architecture including access/metro network segments, as well as the intra‐data center network, thanks to the deployment of advanced optical technologies governed and orchestrated from Software‐Defined Network(SDN)‐enabled control/management planes. SUNSET targets the seamless integration of the aforementioned optical transport and control/management technologies to improve the end‐to‐end network performance, while achieving the joint management and automation of network and IT (data center) resources in a scalable way. In the SUNSET multi-technology network scenario, an effective and dynamic allocation of traffic loads will be performed, always ensuring a high utilization of the underlying network and IT resources.
Programmability in RINA for European Supremacy of Virtualized Networks
January 2014 – June 2016
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.
Integrating advanced optical hardware and SDN for future all optical DCNs
January 2014 – December 2016
The scale and complexity of modern data centres have grown tremendously, increasing the costs of infrastructure equipment, management, and operations. It is therefore critical to revisit the data centre network architecture and develop appropriate network technologies so that future data centres achieve the required large scale at low cost, as well as enabling multi-tenancy services, flexibility, ease of management and operations.
Current technologies are not able to support the scaling of DC networks. In particular today’s DCN hardware solutions lead to architectures that impose unsustainable overheads in terms of capacity, connectivity and energy consumption requirements. Radically new hardware technologies need to be developed, coupled with new frameworks for DCN control and service orchestration in order to enable future-proof DCN architectures.
The COSIGN consortium brings together a unique combination of expertise and resources to deliver novel scalable and future-proof intra-data centre network solutions empowered by advanced optical technologies and a software defined control framework, which will overcome existing and predicted bottlenecks of current architectural solutions. The project will leverage on proper integration of advanced optical hardware and Software Defined Networking technologies for improving performance, scale, and management of network and IT resources towards streamlining the processes of deploying and operating the contemporary dynamic, multi-tenant, and resource-savvy workloads.
