5G-Crosshaul - The 5G Integrated Fronthaul/Backhaul Transport Network

European Project, 5GPPP

Mobile data traffic is forecasted to increase 11-fold between 2013 and 2018. 5G networks serving this mobile data tsunami will require fronthaul and backhaul solutions between the RAN and the packet core capable of dealing with this increased traffic load while fulfilling new stringent 5G service requirements in a cost-efficient manner.
The 5G-Crosshaul project aims at developing a 5G integrated backhaul and fronthaul transport network enabling a flexible and software-defined reconfiguration of all networking elements in a multi-tenant and service-oriented unified management environment. The 5G-Crosshaul transport network envisioned will consist of high-capacity switches and heterogeneous transmission links (e.g., fibre or wireless optics, high-capacity copper, mmWave) interconnecting Remote Radio Heads, 5GPoAs (e.g., macro and small cells), cloud-processing units (mini data centres), and points-of-presence of the core networks of one or multiple service providers. This transport network will flexibly interconnect distributed 5G radio access and core network functions, hosted on in-network cloud nodes, through the implementation of: (i) a control infrastructure using a unified, abstract network model for control plane integration (Xhaul Control Infrastructure, XCI); (ii) a unified data plane encompassing innovative high-capacity transmission technologies and novel deterministic-latency switch architectures (Xhaul Packet Forwarding Element, XFE).

Demonstration and validation of the 5G-Crosshaul technology components developed will be integrated into a software-defined flexible and reconfigurable 5G Test-bed in Berlin. Mobility-related experiments will be performed using Taiwan’s high- speed trains. KPI targets evaluated will include among others a 20% network capacity increase, latencies <1 ms and 30% TCO reduction.
The 5G-Crosshaul proposal addresses the ICT 14-2014 call of the Horizon 2020 Work Programme 2014-15 with a special focus on the P7 objectives defined by the 5GPPP IA

 

5G NORMA

European Project, 5GPPP

The 5G NORMA project is one of the 5G-PPP projects under of the Horizon 2020 framework.

5G NORMA aims to develop a novel mobile network architecture that provides the necessary adaptability in a resource efficient way able to handle fluctuations in traffic demand resulting from heterogeneous and dynamically changing service portfolios and to changing local context.  The developed “multi-service and context-aware adaptation of network functions” will allow for a resource-efficient support of these varying scenarios and help to increase energy-efficiency by always selecting the most energy efficient option.

The “mobile network multi-tenancy” approach to be developed by 5G NORMA will leverage the adaptability  and efficiency of network functions and enable an inherent and dynamic sharing and distribution of  network resources between operators. This will allow operators to increase their revenue through the new services, while leveraging the efficiency of the architecture to do so in a cost-effective way.

5G NORMA will apply concepts from software-defined networking (SDN) and network virtualization (NFV), and, in the long-term, will result in enhanced and flexible 5G base stations, software-based centralized controllers and software-based RAN elements.

5G NORMA work is substantiated by the leading players in the mobile communications ecosystem and aim to underpin Europe’s leadership position in this global design effort. Deliverables will include technical innovations, commercial opportunities and societal benefits.

 

SONATA: Service Programing and Orchestration for Virtualized Software Networks

European Project, 5GPPP

Virtualisation and software networks are a major disruptive technology for communications networks, enabling services to be deployed as software functions running directly in the network on commodity hardware. However, deploying the more complex user-facing applications and services envisioned for 5G networks presents significant technological challenges for development and deployment. SONATA addresses both issues.

For service development, SONATA provides service patterns and description techniques for composed services. A customised SDK is developed to boost the efficiency of developers of network functions and composed services, by integrating catalogue access, editing, debugging, and monitoring analysis tools with service packaging for shipment to an operator.

For deployment, SONATA provides a novel service platform to manage service execution. The platform complements the SDK with functionality to validate service packages. Moreover, it improves on existing platforms by providing a flexible and extensible orchestration framework based on a plugin architecture. Thanks to SONATA’s platform service developers can provide custom algorithms to steer the orchestration of their services: for continuous placement, scaling, life-cycle management and contextualization of services. These algorithms are overseen by executives in the service platform, ensuring trust and resolving any conflict between services.

By combining rapid development and deployment in an open and flexible manner, SONATA is realising an extended DevOps model for network stakeholders.

SONATA validates its approach through novel use-case-driven pilot implementations and disseminates its results widely by releasing its key SDK and platform components as open source software, through scientific publications and standards contributions, which, together, will have a major impact on incumbent stakeholders including network operators and manufacturers and will open the market to third-party developers.

CROSSFIRE - unCooRdinated netwOrk StrategieS for enhanced interFerence, mobIlity, radio Resource, and Energy saving management in LTE-Advanced networks -

An Initial Training Network for LTE-Advanced networks

CROSSFIRE (unCooRdinated netwOrk StrategieS for enhanced interFerence, mobIlity, radio Resource, and Energy saving management in LTE-Advanced networks) is a Multi-Partner Initial Training Network (MITN) Marie Curie project that is focused on providing forward-looking solutions for Long Term Evolution-Advanced (LTE-A) network co-existence including aspects ranging from the physical layer such as co-channel interference and cognition to the user perception of the service, i.e., Quality of Experience (QoE). The project will analyze and propose network virtualization solutions for LTE-A networks, a technology which is envisioned to transform operation of cellular networks in the years to come.

It will create a fully-integrated and multi-disciplinary network of 12 Early Stage Researchers (ESRs) working in 8 first-class institutions distributed in 6 European countries. The consortium is formed by 3 Universities, 1 Research Center and 4 Private Companies. This Network will offer to a group of newly recruited ESRs a cross-sectorial environment to shape their long-term research view and get fundamental methodological tools on various research fields such as, network virtualization, self-organization, cognitive radio, energy saving, and small cell networks.

iJoin - Interworking and JOINt Design of an Open Access and Backhaul Network Architecture for Small Cells based on Cloud Networks -

European Project, FP7 Call 8

Future mobile networks will have to provide an exceptionally greater traffic volume in the near future, expecting an increase of up to 500-1000 times today's throughput by 2020. Since the improvement in the transmission rate obtained with physical layer techniques is limited, the best solution to increase the system throughput is by spatial reuse. In this sense, the use of very dense, low-power, small-cell networks with a very high spatial reuse appears to provide a promising option to handle future data rate demands. Nevertheless, this approach faces several challenges: first, small-cell deployments will require a high degree of coordination due to strong inter-cell interference. Furthermore, heterogeneous backhaul solutions will be used to connect small-cells and core network, but so far, access and backhaul are individually designed and therefore not optimised jointly.

iJOIN introduces the novel concept RAN-as-a-Service (RANaaS), where RAN functionality is flexibly centralised through an open IT platform based on a cloud infrastructure. iJOIN aims for a joint design and optimisation of access and backhaul, operation and management algorithms, and architectural elements, integrating small-cells, heterogeneous backhaul and centralised processing. This solution will optimise the RAN system throughput and provide services instantly and efficiently in cost, energy, complexity and latency wherever and whenever the demand arises. Additionally to the development of technology candidates across PHY, MAC, and the network layer, iJOIN will study the requirements, constraints and implications for existing mobile networks, specifically 3GPP LTE-A.

 

FLAVIA -FLexible Architecture for Virtualizable wireless future Internet Access-

European Project, FP7 Call 5, Objective 1.1: The Network of the Future

Wireless networks importance for the Future Internet is raising at a fast pace as mobile devices increasingly become its entry point. However, today's wireless networks are unable to rapidly adapt to evolving contexts and service needs due to their rigid architectural design. We believe that the wireless Internet's inability to keep up with innovation directly stems from its reliance on the traditional layer-based Internet abstraction. Especially, the Link Layer interface appears way too abstracted from the actual wireless access and coordination needs. FLAVIA fosters a paradigm shift towards the Future Wireless Internet: from pre-designed link services to programmable link processors. The key concept is to expose flexible programmable interfaces enabling service customization and performance optimization through software-based exploitation of low-level operations and control primitives, e.g., transmission timing, frame customization and processing, spectrum and channel management, power control, etc. FLAVIA's approach is based on three main pillars: i) lower the interface between hardware-dependent layers and upper layers, ii) apply a hierarchical decomposition of the MAC/PHY layer functionalities, and iii) open programmable interfaces at different abstraction levels. To prove the viability of this new architectural vision, FLAVIA will prototype its concept on two wireless technologies currently available, 802.11 and 802.16, representing today's two main radio resource allocation philosophies: contention-based and scheduled. Moreover, FLAVIA will assess the applicability of the proposed architecture concepts to the emerging 3GPP standards. FLAVIA's concept will allow boosting innovation and reducing the cost of network upgrades. Operators, manufacturers, network designers, emerging third-party solution developers, and even spontaneous end users, will be able to easily and rapidly optimize and upgrade the wireless network operation, quickly prototype and test their new protocols, and adapt the wireless access operation to emerging scenarios or service needs.

 

CARMEN – CARrier grade MEsh Networks-

European Project, FP7 Call 1, Objective 1.1: The Network of the Future

CARMEN CARMEN, CARrier grade MEsh Networks, studies and specifies a wireless mesh network supporting carrier grade triple-play services for mobile/fixed network operators. Future operator networks will be comprised of a common core network and several access networks, and the CARMEN access network will complement other access technologies by providing a low cost and fast deployment mesh network access technology. The project proposes the integration of heterogeneous wireless technologies in a multi-hop fashion to provide scalable and efficient ubiquitous quad-play carrier services. To address the integration complexity of heterogeneous radio technologies, CARMEN introduces a layer 2.5 located between the subnet layer and the routing layer (the abstract interface in the architecture figure below), in order to abstract technology specific issues into a common set of events and commands. Upper layers will use the abstract interface of layer 2.5 to dynamically adapt functions such as routing, mobility and monitoring. One relevant issue is that CARMEN will provide capacity handling algorithms to exploit specific features of the mesh networks such as the availability of multiple links between two peers (i.e. multipath) or the use of radio broadcast instead of unicast to alleviate the load of broadcast services (e.g. video) in the mesh network. CARMEN will focus on three planes: technology, message transfer, and self-configuration and management, to provide a complete solution for setting up and maintaining a cost-effective carrier grade wireless mesh access network.
