Provides telecommunication managers of large, especially multisite, companies, a basis of information and comparisons helpful in negotiating with the long-distance carriers (Sprint, MCI, AT&T) for private network service that can be customized to fit particular needs. Explains how each of the three
This book constitutes the refereed proceedings of the First International Workshop on Active Networks, IWAN'99, held in Berlin, Germany in June/July 1999. The 30 revised full papers presented were carefully reviewed and selected from a total of 80 submissions. The book is divided in sections on networks architectures, platforms, active management and control, and security. All in all, this book provides a unique state-of-the-art account of architectural aspects, technologies, and prototype systems that will impact the way future networked businesses will be created and managed.

The performance of most digital systems today is limited by their communication or interconnection, not by their logic or memory. As designers strive to make more efficient use of scarce interconnection bandwidth, interconnection networks are emerging as a nearly universal solution to the system-level communication problems for modern digital systems. Interconnection networks have become pervasive in their traditional application as processor-memory and processor-processor interconnect. Point-to-point interconnection networks have replaced buses in an ever widening range of applications that include on-chip interconnect, switches and routers, and I/O systems. In this book, the authors present in a structured way the basic underlying concepts of most interconnection networks and provide representative solutions that have been implemented in the industry or proposed in the research literature. * Gives a coherent, comprehensive treatment of the entire field* Presents a formal statement of the basic concepts, alternative design choices, and design trade-offs* Provides thorough classifications, clear descriptions, accurate definitions, and unified views to structure the knowledge on interconnection networks* Focuses on issues critical to designers
The first chapter of this title concerns virtualization techniques that allow sharing computational resources basically, slicing a real computational environment into virtual computational environments that are isolated from one another. The Xen and OpenFlow virtualization platforms are then presented in Chapter 2 and a performance analysis of both is provided. This chapter also defines the primitives that the network virtualization infrastructure must provide for allowing the piloting plane to manage virtual network elements. Following this, interfaces for system management of the two platforms are proposed in Chapter 3. To control and manage virtual network elements, five primitives that the network virtualization infrastructure must provide are defined: instantiate, delete, migrate, monitor and set. The book then moves on to survey existing control algorithms for virtual networking. It also describes the main challenges for packet forwarding using Xen as a virtualization tool and describes, in more detail, a proposal for local control of virtual networks. Within each physical node, this proposal guarantees the service level acquired by each virtual network, even in the presence of misbehaving virtual networks. Contents 1.

We are at the dawn of an era in networking that has the potential to define a new phase of human existence. This era will be shaped by the digitization and connection of everything and everyone with the goal of automating much of life, effectively creating time by maximizing the efficiency of everything we do and augmenting our intelligence with knowledge that expedites and optimizes decision-making and everyday routines and processes. The Future X Network: A Bell Labs Perspective outlines how Bell Labs sees this future unfolding and the key technological breakthroughs needed at both the architectural and systems levels. Each chapter of the book is dedicated to a major area of change and the network and systems innovation required to realize the technological revolution that will be the essential product of this new digital future.
Most conventional networks are passive, with only basic traffic monitoring, management, routing, and congestion control. At best, they can be called reactive. Deploying new functions and integrating new standards into these architectures is difficult due to the rigid embedding of software and hardware into the network components. Active and Program
The authors meet the growing demands of de-centralized companies that need a secure and functional network using Linux. The only book available that extensively covers the combination of VPN technology and Linux, this volume teaches first hand how to build various VPN solutions with individual setup guides.
The goal of this book is to describe new concepts for Internet next generation. This architecture is based on virtual networking using Cloud and datacenters facilities. Main problems concern 1) the placement of virtual resources for opening a new network on the fly, and 2) the urbanisation of virtual resource implemented on physical network equipment. This architecture deals with mechanisms capable of controlling automatically the placement of all virtual resources within the physical network. In this book, we describe how to create and delete virtual networks on the fly. Indeed, the system is able to create any new network with any kind of resource (e.g., virtual switch, virtual routers, virtual LSRs, virtual optical path, virtual firewall, virtual SIP-based servers, virtual devices, virtual servers, virtual access points, and so on). We will show how this architecture is compatible with new advances in SDN (Software Defined Networking), new high-speed transport protocol like TRILL (Transparent Interconnection of Lots of Links) and LISP (Locator/Identifier Separation Protocol), NGN, IMS, Wi-Fi new generation, and 4G/5G networks. Finally, we introduce the Cloud of security and the virtualisation of secure elements (smartcard) that should definitely transform how to secure the Internet.
