Canada The undersigned hereby recommend to the Faculty of Graduate Studies and Research acceptance of the thesis Development of Open Carrier Grade-Based Platforms Submitted by Jeevithan Muttulingam In partial fulfillment to the requirements for the degree of Master of Applied Science in Technology Innovation Management Victor C. Aitken, Department Chair Department of Systems and Computer Engineering AJ. Bailetti, Thesis Supervisor Carleton University December 2008 11 ABSTRACT The development of open Carrier Grade-Based Platforms (CGBPs) is an emerging phenomenon where the specification for the platform is defined by a consortium of Network Equipment Providers (NEPs), and third party telecommunications components suppliers, and the platform is developed internally by NEPs. Since the specification for the entire platform is open, it fosters an environment for platform development integrating off the shelf component and free open source software building blocks. This research uses three perspectives to examine the development of open CGBPs: ecosystems (Moore, 2005), platform development (Krishnan & Gupta, 2001) and technological infrastructure (Weiss & Birnbaum, 1989). The research provides a model that captures company motivation for participating in the development of open CGBPs, company behaviour, engagement dynamics, and outcomes from participation and propositions anchored around the model. in ACKNOWLEDGMENTS The dedicated guidance of my supervisor Professor Tony Bailetti, who has shown a great interest in the success of my graduate studies, has made this thesis a success. It was indeed my honour to have him as my supervisor. It is important for me to acknowledge the moral support and motivation my family has provided. From childhood, my parents have persuaded me to aim for higher goals in life. I'm grateful for their unconditional love and continuous encouragement. I'm also thankful to my friends who have always stood by me in good and bad times and for all their support. Further, my manager at Ross Video Ltd, Allan Pepper, has made this process easier by granting me the flexibility at work to complete my graduate studies. Hence, my sincere thanks to Allan. I also gratefully acknowledge all the executives and development managers who participated and provided valuable input to this research.

  • Montavista Linux Carrier Grade Edition
    MontaVista Linux Carrier Grade Edition WHITE PAPER ABSTRACT: Communications networks are very different from other kinds of computing applications. Networks require both very high reliability and very high performance. Not only must they process large volumes of data at high speed, but they must do so while limiting their downtime to minutes per year. Network failures can have huge economic consequences and can even result in the loss of life. Additionally, in this post-9/11 world, failure also has a national security dimension. This technical whitepaper introduces MontaVista Linux Carrier Grade Edition— what it is, how it evolved, and how it provides a foundation for developing and deploying carrier-grade applications like those described above.

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.

  • 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.

  • 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

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.
