The evolution of the Internet has been remarkable in the last decade, and no limits are foreseen toward what Europe has defined as “Horizon 2020”. Flagship research programmes have been initiated in Europe, United States, and Asia in the last years addressing the design of the network of the future, so called “Future Internet”. This worldwide trend is rooted on the common understanding that current networks must be transformed to accommodate the expected and the unforeseen demands and requirements. Today, two different lines of work exist to conceptually support this transformation. On the one hand, clean slate approaches (also known as revolutionary) push for a new network design that does not necessarily support the current Internet model. On the other hand, evolutionary approaches aim at improving critical aspects of the network without the need of introducing disruptive changes in this latter. GESTIONA is positioned on this second trend, where the main objective is to contribute to the design of the Future Internet without creating a parallel Internet. While this approach increases the chances of developing products eligible for turning into technology transfer to industry (this is one of the main objectives of the research group in the coming years), it also requires innovation on operational networks, which are increasingly heterogeneous and complex to control and manage. Network operators are currently supporting this network evolution through integration, where traditional telephony networks, TV, public and private networks, are all converging on services offered by a network platform supported by IP over optical network infrastructures. Unfortunately, on the urgency on providing such convergence on the data plane, the Internet community has overlooked other aspects that are critical for the development of the Internet. Three of these key unattended aspects define the pillars in which the GESTIONA proposal will focus on. First, the data plane convergence has not been accompanied by progress on equal footing in the management plane. A clear example refers to the relevance (agreed by both the industry and research communities) that a highly efficient coupling of the network layer (IP) and the optical layer will play on the Future Internet development, in particular as concerns the control and the coordinated management of traffic between these layers. Nowadays, the management of IP and optical networks is completely decoupled and fragmented in network operators, to the extent that both the planning and the operation and maintenance of these networks is carried out by different departments within the same operator, and in practice there is no interoperability (at least in a standardized way) between their respective network management systems. Second, the deployment of new capabilities in the network nodes themselves has been an utopia for the vast majority of researchers. However, the recent emergence of open platforms like JUNOS SDK by JUNIPER and OpenFlow is allowing the scientific community to play an active role in the innovation spiral. In fact, many research opportunities come up when considering these open environments under the paradigm of “programmable” networks, since it is expected that applications running on these environments can examine the state of the network, and dynamically manage the nodes’ configuration on both the network and the optical layers depending on such state. Third, managing security for Internet routing has been systematically postponed “to the future”. The real problem (yet to be solved) is how to manage in a scalable, efficient, and non-disruptive way, the routes and prefixes distributed by the BGP protocol, while guaranteeing authenticity of the routes as well as the ownership of the corresponding prefixes advertised. From the research perspective, the fundamental problem lies in the security management and its guarantees, rather than in the security implementation itself. This is definitely a recurring topic, which is increasingly challenging in view of the Future Internet, requiring deep innovations in the interaction and coordination between the management and control planes. GESTIONA proposes to design and validate novel solutions for network management and control leveraging on these three pillars, namely: i) new paradigms supporting coordinated management between layers on multilayer/multi-provider environments; ii) management of programmable networks on open environments; and iii) new strategies for managing routing security in multi-domain scenarios. The research group submitting this proposal has a wide record of research activities on each one of these pillars (as shown in the curricular section of this document), which supports its capacity to achieve the proposal objectives.
