This book provides you with guidelines to plan, design, roll out, and accomplish network migration activities with a variety of internetworking case studies. It considers both enterprise and service provider scenarios based on the expertise from Juniper Networks engineers. From Metro Ethernet migration approaches to comprehensive network protocol consolidation and integration, each case study covers JUNOS resources to ensure successful completion at each migration phase. In addition to an appendix of automation scripts and examples and guidelines for each step, the book also describes the modern challenges that evolve in IT networks.

The process-centered, information-driven guide to designing and executing complex network migrations and mergers. · Understand the importance of gathering business and technical requirements before a network migration or merger · Prepare high-level migration plans based on the comparison between the two designs · Learn the tools that can help complete such projects efficiently · Properly arrange the testing order to develop low-level plans that minimize downtime · Know the different Service Provider mergers and how to approach each · Utilize different internal and external resources along with creative engineering to successfully complete complex network migrations or mergers The Art of Network Migrations and Mergers for Service Providers is the first book that explains in detail the end-to-end process of putting together high-level and low-level plans for complex migrations and mergers focused solely on the Service Provider space. It details the critical information and tools that are needed to properly execute these types of projects. The book begins by explaining the importance of understanding the requirements of the project. Next, it goes over how to compare the legacy and proposed design and how that leads to the development of the high-level migration plan. It then covers what and how to test to build the low-level plan along with the Methods of Procedures. The book goes into detail about the different types of mergers and how to design for each one of them. It ends with a chapter on variables that could be significant factors for both migrations and mergers.

This book describes the concept of a Software Defined Mobile Network (SDMN), which will impact the network architecture of current LTE (3GPP) networks. SDN will also open up new opportunities for traffic, resource and mobility management, as well as impose new challenges on network security. Therefore, the book addresses the main affected areas such as traffic, resource and mobility management, virtualized traffics transportation, network management, network security and techno economic concepts. Moreover, a complete introduction to SDN and SDMN concepts. Furthermore, the reader will be introduced to cutting-edge knowledge in areas such as network virtualization, as well as SDN concepts relevant to next generation mobile networks. Finally, by the end of the book the reader will be familiar with the feasibility and opportunities of SDMN concepts, and will be able to evaluate the limits of performance and scalability of these new technologies while applying them to mobile broadb and networks.

Readers will discover features they didn't know about before and can't resist putting them into production." —Ethan Banks, CCIE #20655, Packet Pushers Podcast Host

Like the popular guides The MX Series and Juniper QFX5100 Series, this practical book--written by the same author--introduces new QFX10000 concepts in switching and virtualization, specifically in the core of the data center network. The Juniper QFX10000 Series from Juniper Networks is a game-changer. This new book by Douglas Hanks is the authoritative guide.

Network diasporas are but the latest bridge connecting developing economy insiders, with their risk-mitigating knowledge and connections, to outsiders in command of technical know-how and investment capital. This book examines the interaction of expatriate talent with institutions in expatriates' countries of origin in an attempt to make the potential of diasporas and their knowledge a reality. The question of how to trigger and sustain such a virtuous cycle is a central concern of this book. The focus is on the "how to" details of how to design effective diaspora networks and transform brain drain into brain gain.

An oft-repeated adage among telecommunication providers goes, “There are ve things that matter: reliability, reliability, reliability, time to market, and cost. If you can’t do all ve, at least do the rst three. ” Yet, designing and operating reliable networks and services is a Herculean task. Building truly reliable components is unacceptably expensive, forcing us to c- struct reliable systems out of unreliable components. The resulting systems are inherently complex, consisting of many different kinds of components running a variety of different protocols that interact in subtle ways. Inter-networkssuch as the Internet span multiple regions of administrative control, from campus and cor- rate networks to Internet Service Providers, making good end-to-end performance a shared responsibility borne by sometimes uncooperative parties. Moreover, these networks consist not only of routers, but also lower-layer devices such as optical switches and higher-layer components such as rewalls and proxies. And, these components are highly con gurable, leaving ample room for operator error and buggy software. As if that were not dif cult enough, end users understandably care about the performance of their higher-level applications, which has a complicated relationship with the behavior of the underlying network. Despite these challenges, researchers and practitioners alike have made trem- dous strides in improving the reliability of modern networks and services.

This book investigates the diverse and dynamic forms of migration within Africa. Centring themes of agency, resource flows, and transnational networks, the book examines the enduring appeal of the Global South as a place of origin, transit, and destination. Popular media, government pronouncements, and much of the global research discourse continue to be oriented towards migration from the Global South to the Global North, despite the fact that the vast majority of migration is South-South. This book moves beyond these mischaracterisations and instead distinctly focuses on the agency of African migrants and the creative strategies they employ while planning their routes within and across the African continent. Case studies explore the flow of resources such as people, money, skills, and knowledge throughout the continent, while also casting a light on the lived experiences of migrants as they negotiate their sometimes precarious and vulnerable positions. Underpinned by intensive empirical studies, this book challenges prevailing narratives and provides a new way of thinking about South-South Migration. Composed by a majority of scholars from the Global South, the book will be crucial reading for researchers, students, and policy makers with a focus on South-South Migration, Migration and Inequalities, Migration and Development, and Refugee and Humanitarian Studies.

Culture plays a central role in our understanding of migration as an economic phenomenon. This title emphasises on the distinctions in culture between migrants, the families they left behind, and the local population in the migration destination.
