TARIFA: The Atomic Redesign of the Internet Future Architecture

Informacio

Description

Current Internet architecture has remained nearly invariant since its inception in early 70’s. In incorporating all the services and applications evolution made in almost 40 years, the current architecture has become more and more complex and ossified. Applications, services, networks and protocols are evolving very quickly and it has been widely proved that TCP/IP is not able to efficiently cover the emerging demands of applications, mainly due to its rigid layered model.TARIFA proposes a new clean slate network architecture to deploy ubiquitous services avoiding hierarchical layering. TARIFA follows a service-oriented approach for a flow-oriented context-aware network architecture where communications are composed in situ using reusable and indivisible components called Atomic Services and according to the needs and requirements of the requester.

 

Innovation

p>The project keeps in mind two main use cases: an evolutionary use case which demonstrates that the new design of the Future Internet architecture is backwards compatible with the current Internet by building with our approach a service or functionality similar to existing solutions; and a revolutionary use case which demonstrates that the project is actually solving those problems that the current Internet cannot in an efficient manner.

The technical core developments of the project are used to validate the improvements of this new approach. Three aspects are taken into account: context-aware service composition, autonomic network management and scalable routing, naming and addressing.

The project takes into account solutions thought to improve three important issues in the current Internet: energy efficiency, heterogeneity of information and coexistence of networks.

The socio-economic impact of the proposed solution are developed in depth by the project, defining new business models that should be deeply studied by the actors involved in the new value chains proposed.

As a final goal, the project evaluates, validates and demonstrates the results in an integrated environment.

Benefits

TARIFA contributes with new concepts for future derived projects with potential industrial and/or societal benefits basically in the following areas:

  • Context-aware service composition: to study and propose solutions enabling the provisioning of Future Internet services through context-aware service composition. This allows providing adapted and personalized services, dealing with high dynamic and heterogeneous environments, in particular on Future Media Internet and Internet of Things environments.
  • Autonomic network management: to define and design a reliable, scalable and robust network infrastructure based on automatic management principles that allow reacting properly to the network conditions in different scenarios and guaranteeing the end-to-end QoS goals of data flows.
  • New routing & addressing paradigms for the Future Internet: to give solutions achieving better routing scalability taking into account the separation of IP addresses into endpoint Locators and routing Locators and fulfilling the challenges that this solution presents.
  • Socio-economic impact: to design novel business models that can be exploited in the context of the Internet of the Future.
