With the recent exhaustion of IPv4 in North America, Asia, and Europe (and Latin America later this year), it's official: IPv4 is on life-support and is rapidly on its way to becoming a legacy protocol. Meanwhile, IPv6 adoption is surging. More than half of the traffic on the nation's largest mobile network is over IPv6 while a social networking giant plans to no longer use IPv4 internally within 18 months. No matter where you work, as a networking professional, IPv6 adoption is in your future.

Along with that adoption comes the need for an IPv6 address plan. This guide provides a comprehensive overview of how to create one. In three sections--preparation, design, and maintenance--enterprise IT network architects, engineers, and administrators will learn the current best-practices for designing, deploying, and maintaining an effective IPv6 addressing plan.

In our increasingly mobile world the ability to access information on demand at any time and place can satisfy people's information needs as well as confer on them a competitive advantage. The emergence of battery-operated, low-cost and portable computers such as palmtops and PDAs, coupled with the availability and exploitation of wireless networks, have made possible the potential for ubiquitous computing. Through the wireless networks, portable equipments will become an integrated part of existing distributed computing environments, and mobile users can have access to data stored at information servers located at the static portion of the network even while they are on the move. Traditionally, information is retrieved following a request-response model. However, this model is no longer adequate in a wireless computing environment. First, the wireless channel is unreliable and the bandwidth is low compared to the wired counterpart. Second, the environment is essentially asymmetric with a large number of mobile users accessing a small number of servers. Third, battery-operated portable devices can typically operate only for a short time because of the short battery lifespan. Thus, clients are expected to be disconnected most of the time. To overcome these limitations, there has been a proliferation of research efforts on designing data delivery mechanisms to support wireless computing more effectively. Data Dissemination in Wireless Computing Environments focuses on such mechanisms. The purpose is to provide a thorough and comprehensive review of recent advances on energy-efficient data delivery protocols, efficient wireless channel bandwidth utilization, reliable broadcasting and cache invalidation strategies for clients with long disconnection time. Besides surveying existing methods, this book also compares and evaluates some of the more promising schemes.

What can your organization gain by adopting HTTP/2? How about faster, simpler, and more robust websites and applications? This practical guide demonstrates how the latest version of the Hypertext Transfer Protocol can dramatically improve website and application performance. You'll take a deep dive into HTTP/2 details, and learn how this updated protocol is changing the web landscape. HTTP/1.1 has been the primary means of communicating data across the web for the past 20 years, but the level of interaction today has gone well beyond what people envisioned in 1997. With this book, authors Stephen Ludin and Javier Garza show you how HTTP/2 will help speed the execution of modern sites and applications. With this book, you'll explore: Performance challenges that led to the HTTP upgrade HTTP/2 in a nutshell, including benefits and transition methods Existing best practices and hacks to improve web performance HTTP/2 support for browsers, servers, proxies, and content delivery networks How the performance of sites using HTTP/2 compares to their HTTP/1.1 experience HTTP/2's effect on specific issues such as latency, packet loss, and Time to First Byte (TTFB)

This chapter has discussed how a commonbroadcast medium can be shared among many contending users. Multiple access protocols differ primarily by the amount of coordination needed to control potentially conflicting packet transmissions. Ato neextreme is random access where no coordinationis provideda ndp acket collisions arep ossible. Atthe other endo fthe spectrum, the class of fixed assignment access protocols eliminates collisions entirely butpay the price ofadditional overhead required forscheduling user access. Hybrid access protocolsb etweenthese two extremes exist While these protocols attempt to combine the advantages ofrandom andfixed access, they also suffer the c ombined drawbacks and overhead ofboth classes of access schemes. Amongt he many factors that determine the performance ofa n access protocol include the propagation delay/packet transmission timeratio, the message arrival process, the types of feedback information available, the user population, and the ability of the user to sense the activities in the network.

Software systems for wireless and mobile communications are a key component in pervasive computing and are crucial for the materialization of easy-to-use and intel- gent services that people can use ubiquitously. As indicated by its acronym (MOBILe Wireless MiddleWARE, Operating Systems, and Applications), these are the type of systems that form the topic of the MOBILWARE conferencing series. In particular, the goal of MOBILWARE is to provide a forum for researchers and practitioners to disseminate and discuss recent advances in software systems for wireless and mobile communications, ranging from work on communication middleware and operating systems to networking protocols and applications. For its second edition, held in Berlin in April 2009, the MOBILWARE Organizing Committee decided to add a full day of workshops on topics related to the main c- ference. Our goals were threefold: 1. Put together a high-quality workshop program consisting of a few focused wo- shops that would provide ample time for discussion, thus enabling presenters to quickly advance their work and workshop attendees to quickly get an idea of - going work in selected research areas. 2. Provide a more complete picture of ongoing work by not only including technical workshops, but also workshops on business and user aspects. We expected that this multi-viewpoint approach would be an added value as technology, business m- els, and user experiences are usually interrelated. 3. Create a breeding ground for submissions for MOBILWARE 2010 and beyond.

Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn.

O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. "Essential SNMP" explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include:

Expanded coverage of SNMPv1, SNMPv2, and SNMPv3

Expanded coverage of SNMPc

The concepts behind network management and change management

RRDTool and Cricket

The use of scripts for a variety of tasks

How Java can be used to create SNMP applications

Net-SNMP's Perl module

The bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents.

Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than "Essential SNMP, 2nd Edition,"

Cisco routers are everywhere that networks are. They come in all sizes, from inexpensive units for homes and small offices to equipment costing well over $100,000 and capable of routing at gigabit speeds. A fixture in today's networks, Cisco claims roughly 70% of the router market, producing high-end switches, hubs, and other network hardware. One unifying thread runs through the product line: virtually all of Cisco's products run the Internetwork Operating System, or IOS.

If you work with Cisco routers, it's likely that you deal with Cisco's IOS software--an extremely powerful and complex operating system, with an equally complex configuration language. With a cryptic command-line interface and thousands of commands--some of which mean different things in different situations--it doesn't have a reputation for being user-friendly.

Fortunately, there's help. This second edition of "Cisco IOS in a Nutshell" consolidates the most important commands and features of IOS into a single, well-organized volume that you'll find refreshingly user-friendly.

This handy, two-part reference covers IOS configuration for the TCP/IP protocol family. The first section includes chapters on the user interface, configuring lines and interfaces, access lists, routing protocols, and dial-on-demand routing and security. A brief, example-filled tutorial shows you how to accomplish common tasks.

The second part is a classic O'Reilly quick reference to all the commands for working with TCP/IP and the lower-level protocols on which it relies. Brief descriptions and lists of options help you zero in on the commands you for the task at hand. Updated to cover Cisco IOS Software MajorRelease 12.3, this second edition includes lots of examples of the most common configuration steps for the routers themselves. It's a timely guide that any network administrator will come to rely on.

In the setting of multi-party computation, sets of two or more parties with private inputs wish to jointly compute some (predetermined) function of their inputs. General results concerning secure two-party or multi-party computation were first announced in the 1980s. Put briefly, these results assert that under certain assumptions one can construct protocols for securely computing any desired multi-party functionality. However, this research relates only to a setting where a single protocol execution is carried out. In contrast, in modern networks, many different protocol executions are run at the same time.

This book is devoted to the general and systematic study of secure multi-party computation under composition. Despite its emphasis on a theoretically well-founded treatment of the subject, general techniques for designing secure protocols are developed that may even result in schemes or modules to be incorporated in practical systems. The book clarifies fundamental issues regarding security in a multi-execution environment and gives a comprehensive and unique treatment of the composition of secure multi-party protocols.

Software Development for the QUALCOMM BREW Platform provides a soup-to-nuts examination of what it takes to design, develop, and deploy commercially viable applications for the QUALCOMM BREW platform. This new platform for wireless development is the solutions for delivering video and color games onto cell phones as you have seen in television advertisements. QUALCOMM Binary Runtime Environment for Wireless (BREW) is a development platform that allows software developers to create applications that operate on all handsets that utilize the QUALCOMM CDMA chipsets. With over a million BREW-enabled handsets having shipped in the first year of BREW's availability and successful deployment with both a major domestic carrier (Verizon Wireless, with over five million subscribers) and overseas carriers (Telesp and KTF, with other carriers presently running trials with BREW), BREW is poised to become an important player in the wireless handset space. today's handsets to both carriers and software developers, including secure application licensing, integrated billing for application purchases, and down-to-the-metal APIs for high-performance applications including multimedia and gaming applications. Software Development for the QUALCOMM BREW Platform will begin with an introduction to BREW and how it differs from its competitors (J2ME, Palm OS, Symbian, and Pocket PC Phone Edition). After this orientation, the reader learns about what it takes to develop applications for BREW - not just development tools, but the methodology required to bring an application to a carrier for distribution.

This conference in Enschede, The Netherlands, is the sixth in a series of international conferences and workshops under the title Protocols for Multimedia Systems, abbreviated as PROMS. The first PROMS workshop took place in June 1994 in Berlin, Germany, followed by workshops in Salzburg, Austria (October 1995) and Madrid, Spain (October 1996). In 1997, PROMS formed a temporary alliance with Multimedia Networking, a conference previously held in Aizu, Japan, in 1995. This led to the international conference on Protocols for Multimedia Systems - Multimedia Networking, PROMS MmNet, that took place in Santiago, Chile (November 1997). Since then PROMS has been announced as an international conference, although informal contacts and interactive sessions - as in a workshop - were retained as a desirable feature of PROMS. After a gap of three years, PROMS was organized in Cracow, Poland (October 2000), for the fifth time. We consider it a challenge to make this sixth edition of PROMS as successful as the previous events. The goal of the PROMS series of conferences and workshops is to contribute to scientific, strategic, and practical cooperation between research institutes and industrial companies in the area of multimedia protocols. This is also the goal of PROMS 2001. The basic theme of this conference continues to be multimedia protocols, both at the network and application level, although the increasing interest in wireless, mobility, and quality of service as interrelated topics with relevance to multimedia are reflected in the current program.

Multimodal Interfaces represents an emerging interdisciplinary research direction and has become one of the frontiers in Computer Science. Multimodal interfaces aim at efficient, convenient and natural interaction and communication between computers (in their broadest sense) and human users. They will ultimately enable users to interact with computers using their everyday skills. These proceedings include the papers accepted for presentation at the Third International Conference on Multimodal Interfaces (ICMI 2000) held in Beijing, China on 1416 O ctober 2000. The papers were selected from 172 contributions submitted worldwide. Each paper was allocated for review to three members of the Program Committee, which consisted of more than 40 leading researchers in the field. Final decisions of 38 oral papers and 48 poster papers were made based on the reviewers' comments and the desire for a balance of topics. The decision to have a single track conference led to a competitive selection process and it is very likely that some good submissions are not included in this volume. The papers collected here cover a wide range of topics such as affective and perceptual computing, interfaces for wearable and mobile computing, gestures and sign languages, face and facial expression analysis, multilingual interfaces, virtual and augmented reality, speech and handwriting, multimodal integration and application systems. They represent some of the latest progress in multimodal interfaces research.
