Tampereen teknillinen yliopisto - Tampere University of Technology Tampere 2009 ISBN 978-952-15-2134-8 (printed) ISBN 978-952-15-2158-4 (PDF) ISSN 1459-2045 Abstract The rapid development of the mobile network industry has raised considerably the expectations and requirements of the whole chain of stakeholders, from the end users through the mobile network operators and ultimately to the network equipment providers. A key expectation from an end user is service availability, which is a perception that services are continuously operational even in the presence of failures in the mobile network. Network equipment providers have been using carrier-grade platforms to provide various support functions including high availability as reusable assets for products creation. The term carrier-grade refers to a class of systems used in public telecommunications network that deliver up to five nines or six nines (99.999% or 99.9999%) availability. The convergence of communications and information technology in the industry has led to more competition and pressure to reduce development efforts. By creating a service availability standard, Commercial Off-The-Shelf (COTS) software can be bought and integrated into a carrier-grade platform, enabling a company to focus on the core business and concentrate the resource investment onto new innovations. -

Abstract: Server and system administrators have been concerned about the techniques on how to better utilize their computing resources. Today, there are developed many technologies for this purpose, which consists of running multiple applications and also multiple operating systems on the same hardware, like VMWARE, Linux-VServer, VirtualBox, Xen, etc. These systems try to solve the problem of resource allocation from two main aspects: running multiple operating system instances and virtualizing the operating system environment. Our study presents an evaluation of scalability and performance of an operating system virtualization technology known as Solaris Containers, with the main objective on measuring the influence of a security technology known as Solaris Trusted Extensions. Solaris. We will study its advantages and disadvantages and also the overhead that it introduces to the scalability of the system’s main advantages.

During the latest years, a lot of projects have been looking on virtualizing operating system Operating systems environments, such as FreeBSD Jail, Linux- VServer, Virtuozzo etc. This virtualization technique is based in using only one underlying Solaris/OpenSolaris are Operating Systems operating system kernel. Using this paradigm the performing as the main building blocks of computer user has the possibility to run multiple applications systems; they provide the interface between user in isolation from each other. -
Wireless Network Virtualization: Ensuring Carrier Grade Availability
™ AN INTEL COMPANY Wireless Network Virtualization: Ensuring Carrier Grade Availability WHEN IT MATTERS, IT RUNS ON WIND RIVER WIRELESS NETWORK VIRTUALIZATION: ENSURING CARRIER GRADE AVAILABILITY EXECUTIVE SUMMARY The wireless industry’s battle to acquire new subscribers and retain existing ones is accelerating the need for new services. Profit margins are under pressure from the increased infrastructure and operations costs required to satisfy the growing demand. Network functions virtualization (NFV), a rapidly growing initiative in telecom networks, promises to revolutionize how networks are architected and managed. It allows communications service providers (CSPs) to virtualize network functions and consolidate them on standard off-the-shelf servers. Although 4G LTE is effective at meeting the increasing bandwidth demands at lower costs than its predecessors, its mobile base station, E-UTRAN Node B (eNB), located at the edge of the radio access network (RAN), is underutilized at certain times of the day and has grown in complexity, resulting in higher downtime and field maintenance costs. As a result, the eNB is a good candidate for NFV. Cloud-RAN (C-RAN) is the virtualization of the eNB’s control plane and data plane functions, consolidating it in one or more data centers. The result is significantly higher equipment utilization, cost-efficient redundancy to achieve high availability, and lower operations and maintenance costs. However, to realize these benefits, the foundation for virtualized eNBs must be a robust, carrier grade NFV platform that incorporates advanced fault management features. Poor implementation results in lower quality execution with excessive outage and maintenance costs. Wind River® Titanium Cloud is the industry’s first NFV-ready solution that incorporates advanced carrier grade fault, security, performance, and network management features. -
The Server Virtualization Landscape, Circa 2007
ghaff@ illuminata.com Copyright © 2007 Illuminata, Inc. single user license Gordon R Haff Illuminata, Inc. TM The Server Virtualization Bazaar, Circa 2007 Inspired by both industry hype and legitimate customer excitement, many Research Note companies seem to have taken to using the “virtualization” moniker more as the hip phrase of the moment than as something that’s supposed to convey actual meaning. Think of it as “eCommerce” or “Internet-enabled” for the Noughts. The din is loud. It doesn’t help matters that virtualization, in the broad sense of “remapping physical resources to more useful logical ones,” spans a huge swath of Gordon Haff technologies—including some that are so baked-in that most people don’t even 27 July 2007 think of them as virtualization any longer. Personally licensed to Gordon R Haff of Illuminata, Inc. for your personal education and individual work functions. Providing its contents to external parties, including by quotation, violates our copyright and is expressly forbidden. However, one particular group of approaches is capturing an outsized share of the limelight today. That would, of course, be what’s commonly referred to as “server virtualization.” Although server virtualization is in the minds of many inextricably tied to the name of one company—VMware—there are many companies in this space. Their offerings include not only products that let multiple virtual machines (VMs) coexist on a single physical server, but also related approaches such as operating system (OS) virtualization or containers. In the pages that follow, I offer a guide to today’s server virtualization bazaar— which at first glance can perhaps seem just a dreadfully confusing jumble. -
Carrier Grade Virtualization
Carrier Grade Virtualization Leveraging virtualization in Carrier Grade Systems Abstract Network Equipment Providers (NEPs) have been building networking infrastructure equipment able to deliver “carrier grade” services, typically mission-critical services such as voice telephony. In decades past, NEPs have achieved high degrees of availability through purpose-built hardware and software implementations. Today they increasingly build on COTS (Commercial Off The Shelf) hardware and Open Source Software (OSS), freeing their engineering resources to focus on core telephony competencies. The move to COTS and OSS requires that these hardware and software components be available from an ecosystem of suppliers, and that they interoperate seamlessly. Bodies such as The Linux Foundation (LF), the Service Availability Forum (SA Forum) and PICMG have defined standards and specifications such as carrier grade OSes (CGLinux), Service Availability Forum APIs and AdvancedTCA hardware to target carrier grade applications. Recent advances have made virtualization appealing for carrier class equipment by permitting significant cost reduction through consolidation of workloads and of physical hardware. Virtualization also transparently lets NEPs and other OEMs (Original Equipment Manufacturers) leverage multi-core processors to run legacy software designed for uniprocessor hardware. However, virtualization needs to meet specific requirements to enable network equipment deploying this technology to meet industry expectations for carrier grade systems. This -
Virtual Containers: Asset Management Best Practices and Licensing Considerations
Virtual Containers: Asset Management Best Practices and Licensing Considerations Virtual containers have seen tremendous adoption and growth within all industries. However, in terms of IT asset management, cont- ainers are not being managed and are an unknown area of risk for many of our clients. Because it is a newer technology, there is very little information about managing containers and how to address the emerging SAM & ITAM challenges they bring. Due to this lack of public information, Anglepoint has published this whitepaper on navigating the world of containers, with an empha- sis on asset management and licensing. We will cover everything from the history of containers, to what containers are, the benefits of containers, asset management best practices, and some publisher-specific licensing considerations. A BRIEF HISTORY OF VIRTUAL CONTAINERS The first proper containers came from the Linux world as LXC (LinuX Containers) in 2008. However, it wasn’t until 2013 that containers entered the IT public consciousness, when Docker came onto the scene with Enterprise usage in mind. Even then, though, it was more of an enthusiast’s technology. In 2015, Google released and open sourced Kubernetes which manages and ‘orchestrates’ containers. However, it wasn’t until 2017 that Docker and Kubernetes had matured enough to be considered for production use within corporate environments. 2017 also saw VMware, Microsoft, and Amazon beginning to support and offer solutions for Kubernetes and Docker on their top-tier cloud infrastructure. WHAT IS A CONTAINER? Often, people conflate the term ‘container’ with multiple technologies that make up the container ecosystem. Let’s look at what a modern container is at the most fundamental level. -
Energy Efficiency in Office Computing Environments

Reviewer: Prof. Hermann de Meer Professor of Computer Networks and Communications University of Passau Innstr. 43 94032 Passau, Germany Email: [email protected] Web: http://www.net.fim.uni-passau.de 2. Reviewer: Prof. David Hutchison Director of InfoLab21 and Professor of Computing Lancaster University LA1 4WA Lancaster, UK Email: [email protected] Web: http://www.infolab21.lancs.ac.uk Abstract The increasing cost of energy and the worldwide desire to reduce CO2 emissions has raised concern about the energy efficiency of information and communica- tion technology. Whilst research has focused on data centres recently, this thesis identifies office computing environments as significant consumers of energy. Office computing environments offer great potential for energy savings: On one hand, such environments consist of a large number of hosts. On the other hand, these hosts often remain turned on 24 hours per day while being underutilised or even idle. This thesis analyzes the energy consumption within office computing environments and suggests an energy-efficient virtualized office environment. The office environment is virtualized to achieve flexible virtualized office resources that enable an energy-based resource management. This resource management stops idle services and idle hosts from consuming resources within the office and consolidates utilised office services on office hosts. This increases the utilisation of some hosts while other hosts are turned off to save energy. The suggested architecture is based on a decentralized approach that can be applied to all kinds of office computing environments, even if no centralized data centre infrastructure is available. -
