Huawei Technologies Co. Ltd. /ˈwɑːˌweɪ/ is a Chinese multinational networking and telecommunications equipment and services company headquartered in Shenzhen, Guangdong. It is the largest telecommunications equipment maker in the world, having overtaken Ericsson in 2012.Huawei was founded in 1987 by Ren Zhengfei, a former engineer in the People's Liberation Army. At the time of its establishment Huawei was focused on manufacturing phone switches, but has since expanded its business to include building telecommunications networks; providing operational and consulting services and equipment to enterprises inside and outside of China; and manufacturing communications devices for the consumer market. Huawei has over 140,000 employees, around 46% of whom are engaged in research and development . It has 21 R&D institutes in countries including China, the United States, Canada, UK, Pakistan, France, Germany, Colombia, Sweden, Ireland, India, Russia, and Turkey, and in 2013 invested US$5 billion in R&D.In 2010, Huawei recorded profit of 23.8 billion CNY . Its products and services have been deployed in more than 140 countries and it currently serves 45 of the world's 50 largest telecoms operators. Wikipedia.

Energy sustainability is key to future mobile networks due to their foreseen capacity upsurge. The objective of the ETN SCAVENGE (Sustainable CellulAr networks harVEstiNG ambient Energy) is to create a training network for early-stage researchers (ESRs) who will contribute to the design and implementation of eco-friendly and sustainable next-generation (5G) networks and become leaders in the related scientific, technological, and industrial initiatives. Sustainable networks are based on the premise that environmental energy can be scavenged through dedicated harvesting hardware so as to power 5G base stations (BSs) and the end devices (mobile terminals, sensors and machines). To realise this vision, the project will take a complete approach, encompassing the characterisation of intermittent and/or erratic energy sources, the development of theoretical models, and the design, optimisation and proof-of-concept implementation of core network, BS and mobile elements as well as their integration with the smart electrical grid. The consortium is composed of world-class research centres and companies that are in the forefront of mobile communication and renewable energy research and technology development. The attitude of the industrial partners towards the strong investment in R&D and their strategic vision are fully aligned with the mission of this project, making them perfectly fit for this consortium. This grants a well-balanced project with genuine and strong technical interactions. The ESRs will have a unique opportunity towards professional growth in light of dedicated cross-partner training activities and through the interaction with the Partner Organisations, which also include relevant stakeholders in the envisioned market. All of this will ensure that the trained researchers will be successfully employed at the end of the research program.

A flexible and programmable forwarding plane is essential to maximize the value of Software-Defined Networks (SDN). In this paper, we propose Protocol-Oblivious Forwarding (POF) as a key enabler for highly flexible and programmable SDN. Our goal is to remove any dependency on protocol-specific configurations on the forwarding elements and enhance the data-path with new stateful instructions to support genuine software defined networking behavior. A generic flow instruction set (FIS) is defined to fulfill this purpose. POF helps to lower network cost by using commodity forwarding elements and to create new value by enabling numerous innovative network services. We built both hardware-based and open source software-based prototypes to demonstrate the feasibility and advantages of POF. We report the preliminary evaluation results and the insights we learnt from the experiments. POF is future-proof and expressive. We believe it represents a promising direction to evolve the OpenFlow protocol and the future SDN forwarding elements. © 2013 ACM. Source

The ten gigabit passive optical network (XG-PON) system is the newest member of the ITU-T family of passive optical network standards. XG-PON is the result of a 3 year project involving the full service access network (FSAN) group and ITU-T study group 15 (SG15) question 2. This paper reviews the deliberations that led to the selection of the XG-PON system, and then explains the three primary layers of the system: physical, protocol, and management. The paper concludes with information on standards and implementations of the system, and on future work in this area. © 2006 IEEE. Source

The Third Generation Partnership Project defined multimedia broadcast/multicast service in 2005 to optimize the distribution of video traffic. This standard covers the terminal, radio, core network, and user service aspects. This MBMS standard has evolved into enhanced MBMS (eMBMS) that builds on top of the 3GPP Long Term Evolution standard. eMBMS evolution brings improved performance thanks to higher and more flexible LTE bit rates, single frequency network operations, and carrier configuration flexibility. 3GPP Rel-11 also brings improvements in the areas of service layer with, for example, video codec for higher resolutions and frame rate, and forward error correction. eMBMS allows offloading of the LTE network and backhaul. It enables the possibility to deliver premium content to many users with secured quality of service in defined areas. Other important use cases are pushed content via user equipment caching and machine-to-machine services. This article describes the relevant use cases for eMBMS in terms of service. It then gives a tutorial on eMBMS, in particular highlighting the evolution over MBMS. The scope comprises the radio access, core network, and service layer. © 2012 IEEE. Source

5G will have to cope with a high degree of heterogeneity in terms of: (a) services (mobile broadband, massive machine and mission critical communications, broad-/multicast services and vehicular communications); (b) device classes (low-end sensors to high-end tablets); (c) deployment types (macro and small cells); (d) environments (low-density to ultra-dense urban); (e) mobility levels (static to high-speed transport). Consequently, diverse and often contradicting Key Performance Indicators need to be supported, such as high capacity/user-rates, low latency, high reliability, ubiquitous coverage, high mobility, massive number of devices, low cost/energy consumption. 4G is not designed to meet such a high degree of heterogeneity efficiently. Moreover, having multiple radio access technologies for multi-service support below 6GHz will be too costly. FANTASTIC-5G will develop a new multi-service Air Interface (AI) for below 6 GHz through a modular design. To allow the system to adapt to the anticipated heterogeneity, the pursued properties are: flexibility, scalability, versatility, efficiency, future-proofness. To this end, we will develop the technical AI components (e.g. flexible waveform and frame design, scalable multiple access procedures, adaptive retransmission schemes, enhanced multi-antenna schemes with/without cooperation, advanced multi-user detection, interference coordination, support for ultra-dense cell layouts, multi-cell radio resource management, device-to-device) and integrate them into an overall AI framework where adaptation to the above described sources of heterogeneity will be accomplished. Our work will also comprise intense validation and system level simulations. FANTASTIC-5G includes partners being active in forerunning projects like METIS, 5GNOW and EMPATHIC ensuring the exploitation of the respective outcomes. The consortium possesses the main stakeholders for innovation and impacting standardization, maintaining Europe at the forefront.
