Experimental UpdateLess Evolutive Routing
October 2010 – June 2014
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.
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.
Scalable Tunable and Resilient Optical Networks Guaranteeing Extremely-High Speed Transport (STRONGEST)
January 2010 – December 2012
STRONGEST’s main goal is to design and demonstrate an evolutionary ultra-high capacity multilayer transport network, based on optimized integration of optical and packet nodes, and equipped with a multi-domain, multi-technology control plane, overcoming the problems of current networks that still provide limited scalability, are not cost-effective and do not properly guarantee end-to-end quality of service. STRONGEST is an industry led project; the consortium brings together major European industrial players, leading Telecom operators, Universities and Research Centres and as such, it enables the necessary synergies and creates an ideal environment for innovation and development. The European scale of the project is made necessary by the development of a new reality in which countries and federations are immensely and inextricably linked. To have a common view at European level is essential to apply the project’s outcomes. A major impact from STRONGEST will be to strengthen the position of European industry in the field of Future Internet and to reinforce European leadership in optical networks technologies. The design of a more efficient transport network with reduced cost per bit and the particular attention to energy efficiency will turn into benefit to the entire Community. Network Operators have a tough target to reduce CO2 emissions, whilst at the same time supporting significantly higher information bandwidth. They will use the results of STRONGEST, which will provide the optimum transport network architecture to achieve these targets. STRONGEST results will be exploited by Vendors to develop traffic engineering solutions running in multi-technologies and multi-domain context, and the related control plane in both legacy nodes and new optical/packet nodes. Academic Partners plan to use the STRONGEST results for further enhancement of knowledge transfer, and training and skills creation in the field of telecommunication networks, particularly in the field of optical networks.
Future Internet: Eficiencia en las redes de altas prestaciones
May 2011 – September 2012
The mismatches in the design objectives between the original and the future Internet avoid its widespread deployment at the expected scales. The challenges with regard to the high-performance IP (metro and core) network infrastructure involve all the layers: physical layer and switching technologies, traffic engineering, control and management, etc. The goal of this Thematic Network aims at building a platform to create synergies and close collaboration among the different Spanish groups with expertise in the Internet topic.
