Graph Neural Networks (GNN) have been recently proposed to learn, model and generalize over graph structured data. Computer Networks are fundamentally graphs, and many of its relevant characteristics -such as topology and routing- are represented as graph-structured data. In this context, GNN are a central tool to apply ML techniques to Computer Networks. GNN can learn the relationship of complex network characteristics and build relevant models that can be useful to plan and manage the network. In addition and in combination with Deep-Reinforcement Learning (DRL) techniques, GNN can help developing autonomous network optimization mechanisms that result in unprecedented performance, achieving the ultimate vision of self-driving networks. The Barcelona Neural Networking Center (BNN-UPC) has been created as an initiative of Prof. Albert Cabellos and Prof. Pere Barlet at UPC (Universitat Politècnica de Catalunya) with the main goals of carrying fundamental research in the field of Graph Neural Network applied to Computer Networks, and educating and training the new generation of students.

The main design principles in computer architecture have shifted from a monolithic scaling-driven approach towards an emergence of heterogeneous architectures that tightly co-integrate multiple specialized computing and memory units. This is motivated by the urgent need of very high parallelism and by energy constraints. This heterogeneous hardware specialization requires interconnection mechanisms that integrate the architecture. State-of-the-art approaches are 3D stacking and 2.D architectures complemented with a Network-on-Chip (NoC) to interconnect the components. However, such interconnects are fundamentally monolithic and rigid, and are unable to provide the efficiency and architectural flexibility required by current and future key ICT applications. The main challenge is to introduce diversification and specialization in heterogeneous processor architectures while ensuring their generality and scalability. In order to achieve this, the WiPLASH project aims to pioneer an on-chip wireless communication plane able to provide architectural plasticity, reconfigurability and adaptation to the application requirements with near-ASIC efficiency but without any loss of generality. For this, the WiPLASH consortium will provide solid experimental foundations of the key enablers of on-chip wireless communication at the functional unit level as well as their technological and architectural integration. The main goals are: (i) prototype a miniaturized and tunable graphene antenna in the terahertz band, (ii) co-integrate graphene RF components with submillimeter-wave transceivers and (iii) demonstrate low-power reconfigurable wireless chip-scale networks. The culminating goal is to demonstrate that the wireless plane offers the plasticity required by future computing platforms by improving at least one key application (mainly biologically-plausible deep learning architectures) by 10X in terms of execution speed and energy-delay product over a state-of-the-art baseline.

Leaving the current 4th generation of mobile communications behind, 5G will represent a disruptive paradigm shift integrating 5G Radio Access Networks (RANs), ultra-high capacity access/metro/core optical networks and intra-datacenter network and computational resources into a single converged 5G network infrastructure. Thanks to an extensive deployment of network virtualization techniques leveraged by Software-Defined Networking (SDN) and Network Function Virtualization (NFV) technologies, such a 5G network infrastructure will have to be capable of inter-connecting anything (people, things, processes, contents, etc.) anywhere, no matter the geographic location, and over a set of network services truly meeting their diverse communication requirements (e.g., in terms of bandwidth, latency, reliability, etc.). Furthermore, these network services will have to be orchestrated end-to-end over several network and IT resource segments with high scalability, dynamicity and reactivity upon unexpected traffic and resource state changes, all this in an energy-efficient fashion. The present coordinated project proposal ALLIANCE ambitiously aims at architecting, from top to bottom, a converged 5G-enabled network infrastructure satisfying those needs to effectively realize the envisioned upcoming Digital Society. Joining the long expertise of two multidisciplinary research teams, ALLIANCE will investigate the appropriateness of several networking solutions for 5G, such as SDN/NFV on top of an ultra-high capacity spatially and spectrally flexible all-optical network infrastructure, or the OpenOverlayRouter (OOR) and the clean-slate Recursive Inter-Network Architecture (RINA) over packet networks, including access, metro, core and datacentre networks. Evaluation activities will not only consist of theoretical and simulation-based results, but also experimental activities over representative network test-beds implementing the aforementioned networking solutions for 5G, as a way to completely assess their performance in real network scenarios. ALLIANCE relies on cognitive QoE-driven management and orchestration, which optimises level service quality without network resource over-provisioning. In particular, an ambitious goal of the ALLIANCE proposal is to design and implement a Knowledge-Defined Networking (KDN)-based orchestration layer, implementing Deep learning (DL) techniques toward optimal end-to-end service provisioning. Last but not least, on the RAN segment, efforts will also be devoted in ALLIANCE to investigate on novel graphene mmWave-THz antenna systems for their potential use in 5G, as well as protocols for applications like Wireless Network on Chip (WNoC). As a final coordinated task, some of the prototypes developed by the two ALLIANCE sub-projects will be integrated in an proof-of-concept, which will demonstrate the feasibility and functionality of the 5G-enabled ALLIANCE network infrastructure, and its composing networking solutions.
Nanotechnology involves development of materials and even complete systems at atomic, molecular or macromolecular levels in the dimension range of approximately 1-500 nanometers. Current investigation looks to provide detailed understanding of unique properties that materials exhibit at the nano-scale size. This technology gives us the possibility to create taylormade materials, trough the atom manipulation. If we know the atom's properties, we can organize them in a way that give us, as a result, materials with special conditions that do not necessary exist in the nature.
One of the areas where nanotechnology holds the most significant promise is the area of networks. The main idea of nano-networks or nano-scale communication has been initiated from the on-chip communication for electronic circuit design domains (Network-On-Chip). This project is focused on nano-networks as a response to the necessity to study the technical issues related to the intersection of nanotechnologies with networking and communication. Nano-networks will allow communicating nanomachines, defined as molecular scale objects that are capable to perform simple tasks.
