Infrastructure sharing of 5G mobile core networks on an SDN/NFV platform

When looking towards the deployment of 5G network architectures, mobile network operators will continue to face many challenges. The number of customers is approaching maximum market penetration, the number of devices per customer is increasing, and the number of non-human operated devices estimated to approach towards the tens of billions, network operators have a formidable task ahead of them. The proliferation of cloud computing techniques has created a multitude of applications for network services deployments, and at the forefront is the adoption of Software-Defined Networking (SDN) and Network Functions Virtualisation (NFV). Mobile network operators (MNO) have the opportunity to leverage these technologies so that they can enable the delivery of traditional networking functionality in cloud environments. The benefit of this is reductions seen in the capital and operational expenditures of network infrastructure. When going for NFV, how a Virtualised Network Function (VNF) is designed, implemented, and placed over physical infrastructure can play a vital role on the performance metrics achieved by the network function. Not paying careful attention to this aspect could lead to the drastically reduced performance of network functions thus defeating the purpose of going for virtualisation solutions. The success of mobile network operators in the 5G arena will depend heavily on their ability to shift from their old operational models and embrace new technologies, design principles and innovation in both the business and technical aspects of the environment. The primary goal of this thesis is to design, implement and evaluate the viability of data centre and cloud network infrastructure sharing use case. More specifically, the core question addressed by this thesis is how virtualisation of network functions in a shared infrastructure environment can be achieved without adverse performance degradation. 5G should be operational with high penetration beyond the year 2020 with data traffic rates increasing exponentially and the number of connected devices expected to surpass tens of billions. Requirements for 5G mobile networks include higher flexibility, scalability, cost effectiveness and energy efficiency. Towards these goals, Software Defined Networking (SDN) and Network Functions Virtualisation have been adopted in recent proposals for future mobile networks architectures because they are considered critical technologies for 5G. A Shared Infrastructure Management Framework was designed and implemented for this purpose. This framework was further enhanced for performance optimisation of network functions and underlying physical infrastructure. The objective achieved was the identification of requirements for the design and development of an experimental testbed for future 5G mobile networks. This testbed deploys high performance virtualised network functions (VNFs) while catering for the infrastructure sharing use case of multiple network operators. The management and orchestration of the VNFs allow for automation, scalability, fault recovery, and security to be evaluated. The testbed developed is readily re-creatable and based on open-source software

Design and Architecture of Dell Acceleration Appliances for Database (DAAD): A Practical Approach with High Availability Guaranteed

Abstract-As IT organizations are pursuing database High Availability (HA) solutions to ensure and protest critical commercial data, the challenge is to leverage the three-fold key dimensions: cost, performance and availability. A successful solution needs to integrate Database Management System (DBMS) seamlessly with back-end storage and offer good performance and customer data protection. Through extensively investigating plenty of productions in the market, Oracle database is a leading solution for business critical application. As a cost effective solution, it could reduce business risk and achieve data availability, performance, and Return on Investment (ROI). On the other aspect, high-end storage solution, Storage Attach Network (SAN) based on Fibre Channel protocol can be easy to deploy with Oracle database and match end-user's requirements. In this paper, we will present a design of high available database on new reference architectures. The implementation of design is based on Oracle database with Dell Acceleration Appliances for Databases (DAAD), which introduces flash technology by Fusion-IO. To demonstrate practical performances, we built a proof-ofconcept platform and compared the platform with a traditional 96-SAS-drive platform. The results show that our approach can deliver more than 1-million random Input/output Operations Per Second (IOPS) that is 27 times faster than the traditional platform and it can also achieve a 96% reduction in the latencies, thus showing the scalability of the approach with massive database nodes. Therefore, our approach provides not only an ultra-fast storage solution to boost database performances but it also offers a flexible and high available design to achieve zerodowntime database

BEYOND ALL LIMITS : Procedings on International Conference on Sustainability in Architecture, Planning, and Design : 11-12, 13 May 2022

[Italiano]: Il volume raccoglie gli atti della seconda edizione del convegno “BEYOND ALL LIMITS. International Conference on Sustainability in Architecture, Planning, and Design”, tenutosi nei giorni 11 e 12 maggio 2022, presso il Complesso del Belvedere di San Leucio, sede di Officina Vanvitelli. Il convegno è stato promosso e organizzato dal Dipartimento di Architettura e Disegno Industriale dell'Università degli Studi della Campania “Luigi Vanvitelli”, in partnership con la Faculty of Architecture della Çankaya University di Ankara e la Faculty of Engineering della University of Strathclyde di Glasgow. L’obiettivo principale di questo convegno scientifico e multidisciplinare, che ha interessato i campi dell'architettura, della pianificazione e del design, è stato quello di affrontare il tema della sostenibilità all’interno dell'attuale dibattito internazionale scaturito dal New European Bauhaus (NEB)./[English]: This volume collects the Proceedings of the second edition of the conference “BEYOND ALL LIMITS.

Data and the city – accessibility and openness. a cybersalon paper on open data

This paper showcases examples of bottom–up open data and smart city applications and identifies lessons for future such efforts. Examples include Changify, a neighbourhood-based platform for residents, businesses, and companies; Open Sensors, which provides APIs to help businesses, startups, and individuals develop applications for the Internet of Things; and Cybersalon’s Hackney Treasures. a location-based mobile app that uses Wikipedia entries geolocated in Hackney borough to map notable local residents. Other experiments with sensors and open data by Cybersalon members include Ilze Black and Nanda Khaorapapong's The Breather, a "breathing" balloon that uses high-end, sophisticated sensors to make air quality visible; and James Moulding's AirPublic, which measures pollution levels. Based on Cybersalon's experience to date, getting data to the people is difficult, circuitous, and slow, requiring an intricate process of leadership, public relations, and perseverance. Although there are myriad tools and initiatives, there is no one solution for the actual transfer of that data
