A service-oriented hybrid access network and clouds architecture

Many telecom operators are deploying their own cloud infrastructure with the two-fold objective of providing cloud services to their customers and enabling network function virtualization. In this article we present an architecture we call SHINE, which focuses on orchestrating cloud with heterogeneous access and core networks. In this architecture intra and inter DC connectivity is dynamically controlled, maximizing the overall performance in terms of throughput and latency while minimizing total costs. The main building blocks are: a future-proof network architecture that can scale to offer potentially unlimited bandwidth based on an active remote node (ARN) to interface end-users and the core network; an innovative distributed DC architecture consisting of micro-DCs placed in selected core locations to accelerate content delivery, reducing core network traffic, and ensuring very low latency; and dynamic orchestration of the distributed DC and access and core network segments. SHINE will provide unprecedented quality of experience, greatly reducing costs by coordinating network and cloud and facilitating service chaining by virtualizing network functions.Peer ReviewedPostprint (author’s final draft

Mapping Cloud-Edge-IoT opportunities and challenges in Europe

While current data processing predominantly occurs in centralized facilities, with a minor portion handled by smart objects, a shift is anticipated, with a surge in data originating from smart devices. This evolution necessitates reconfiguring the infrastructure, emphasising computing capabilities at the cloud's "edge" closer to data sources. This change symbolises the merging of cloud, edge, and IoT technologies into a unified network infrastructure - a Computing Continuum - poised to redefine tech interactions, offering novel prospects across diverse sectors. The computing continuum is emerging as a cornerstone of tech advancement in the contemporary digital era. This paper provides an in-depth exploration of the computing continuum, highlighting its potential, practical implications, and the adjustments required to tackle existing challenges. It emphasises the continuum's real-world applications, market trends, and its significance in shaping Europe's tech future

Public safety mobile broadband: draft report

The draft report was released on 23 September 2015. You are invited to examine the report and to make written submissions by Wednesday 28 October 2015. This draft report looks at the best way to deliver a Public Safety Mobile Broadband (PSMB) capability for emergency services that is reliable, interoperable and works across Australia. The final report will be released in December 2015. Key points Public safety mobile broadband (PSMB) holds considerable potential to improve how the police, fire, ambulance and other public safety agencies (PSAs) deliver their services. It will allow frontline officers to access high-speed video, images, location tracking and much more. PSAs currently rely on their own radio networks for voice communications and some low-speed data. Mobile broadband use has been modest due to concerns that the quality of commercial services is insufficient to support \u27mission critical\u27 operations. The network capacity that PSAs require is uncertain. PSAs are seeking a higher quality of service than what is currently available on commercial networks. However, the standards required (in terms of coverage, reliability, security, priority access and so on) are not specific. There are many ways to provide a PSMB capability, including the construction of a dedicated network, a commercial approach, or some combination (hybrid) of the two. A dedicated network would give PSAs access to (and control over) their own PSMB network using their own parcel of spectrum. A commercial approach would mean that PSAs obtain PSMB services from one or more of the commercial mobile carriers through a contract for service. The Commission has undertaken an illustrative evaluation of the costs of several specific delivery options over a 20-year period. The cost of a dedicated network was estimated to be in the order of $6.1 billion, compared to$2.1 billion for a commercial option. Even the lowest-cost hybrid option is twice as expensive as a commercial option. A commercial option is cheaper because it requires significantly less \u27new investment\u27 than a dedicated or hybrid option as considerable existing infrastructure could be used or shared. Risk factors also influence the relative merits of different options. A dedicated network would likely take longer to deliver and offer less flexibility to scale up network capacity in the short term, relative to other options. Providing priority services under commercial or hybrid options would be more technically complex than under a dedicated option. There are also commercial risks arising from limited competition and supplier \u27lock-in\u27. The benefits of each option are not expected to vary markedly, since the options under evaluation have been designed to deliver a similar level of PSMB capability. On that basis, the cost evaluation is likely to provide the best guide to net community benefit for each option. On first principles, a commercial approach represents the most efficient, effective and economical way of delivering a PSMB capability to PSAs. Small-scale trials would provide an opportunity for jurisdictions to gain confidence in a commercial approach; gauge the costs, benefits and risks of PSMB; and develop a business case for a wider-scale roll out. Competitive procurement is essential. Splitting up tenders, leveraging infrastructure assets and insisting on open technology standards can help governments secure value for money. Achieving interoperability will require jurisdictions to agree on common technical standards. PSAs will also need to adapt their operations to make the most of PSMB. This includes protocols for sharing information and network capacity among agencies. Spectrum allocation is an Australian Government responsibility. Any spectrum made available for PSMB should be priced at its opportunity cost to support its efficient use

An Analysis of a BYOD Program in a School District

This project documents and analyzes the preparation and execution of a bring your own device program implemented in a local affluent school district. The project looks at the implementation from a cost/benefit perspective, identifying the stated goals of the program and working to develop a method of measurement for evaluation. It examines the technical infrastructure upgrades and configuration required to ensure a smooth roll­out. The project also examines bring your own device programs in several other industries, identifying the motivations and methods of measurement as means for developing recommendations based in experience

A comparative investigation on the application and performance of Femtocell against Wi-Fi networks in an indoor environment

Due to the strenuous demands on the available spectrum and bandwidth, alongside the ever increasing rate at which data traffic is growing and the poor quality of experience QoE) faced with indoor communications, in order for cellular networks to remain dominant in areas pertaining to voice and data services, cellular service providers have to reform their marketing and service delivery strategies together with their overall network rchitecture. To accomplish this leap forward in performance, cellular service operators need to employ a network topology, which makes use of a mix of macrocells and small cells, effectively evolving the network, bringing it closer to the end-­‐user. This investigation explores the use of small cell technology, specifically Femtocell technology in comparison to the already employed Wi-­‐Fi technology as a viable solution to poor indoor communications.The performance evolution is done by comparing key areas in the every day use of Internet communications. These include HTTP testing, RTP testing and VoIP testing. Results are explained and the modes of operation of both technologies are compared
