Computer network devices need to be as easy for consumers to set up as stereo equipment. Universal Plug and Play (UPnP) is the technology that can make this happen. This book is primarily a software developer's guide for enabling UPnP, but it also provides a great introduction for those new to the technology.

Inhaltsangabe:Abstract: Successive to a preceding study about Service Discovery, this thesis covers the topics Service Description and Service Access. Starting with an analysis and comparison of existing technologies, a new protocol for the service access was developed and an operating environment, capable of accessing services of any type was programmed. Thereby emphasis is placed an high scalability, extensibility, modularity and comprehensive documentation, to provide easy association with existing or future works. The first part deals with the various versions of Service Descriptions, followed by a description of the service access methods and concluding with a comprising comparison. All technologies or protocols qualified for Service Discovery and Access discovered during this diploma thesis are discussed. The main part comprises the software implementation which was written in Java, including a comprehensive documentation containing, among others, the protocol specification, software architecture, an user guide and proposals for advancements. Zusammenfassung: Aufbauend auf einer vorangegangenen Arbeit über Service Discovery, werden in dieser Diplomarbeit die Themen Service Description und Service Access behandelt. Beginnend mit einer Analyse und dem Vergleich existierender Techologien, wurde ein neues Protokoll für den dynamischen Dienstzugriff entwickelt und eine funktionsfähige Umgebung programmiert, die mittels dieses Protokolls auf Dienste jeglicher Art zugreifen kann. Dabei wurde das Augenmerk auf eine hohe Skalierbarkeit, Erweiterbarkeit, Modularität und umfassende Dokumentation gelegt, so dass es nicht schwer fallen sollte, die Software mit folgenden oder existierenden Arbeiten zu verknüpfen. Im ersten Teil wird auf die verschiedenen Varianten der Dienstbeschreibungen eingegangen, gefolgt von einer Beschreibung der Dienstzugriffe und anschließend einem zusammenfassenden Vergleich. Aufgeführt sind dabei alle für Service Discovery und Access geeigneten Technologien, bzw. Protokolle, die im Rahmen der Diplomarbeit aufgefunden wurden. Der Hauptteil der Arbeit umfasst die Implementierung der Software, die in Java geschrieben wurde, inklusive einer umfassenden Dokumentation dazu, die unter anderem die Protokollspezifikation, die Architektur der Software, eine Bedienungsanleitung und Vorschläge zur Weiterentwicklung beinhaltet.

This book constitutes the refereed post-conference proceedings of the 15th International Workshop on Groupware: Design, Implementation, and Use, held in Peso da Régua, Douro, Portugal, during September 13-17, 2009. The 30 papers presented were carefully reviewed and selected from numerous submission. The topics covered are mobile collaboration, social aspects of collaboration, technology for CSCW, groupware evaluation, CSCW design, geo collaboration, collaborative learning, and modeling CSCW.

"This book provides solutions to these challenges, practices and understanding of contemporary theories and empirical analysis for systems engineering in a way that achieves service excellence"--Provided by publisher.

This book describes the architecture and protocols for interconnecting media devices in home networks. The architecture and protocols described in this book have been developed during the last 10 years by R&D teams from several companies working jointly in two industry organizations known as UPnP and DLNA. This book mainly deals with the DLNA (Digital Living Network Alliance) protocol. This text is especially relevant for the design and development of smart homes, where media devices, communication devices, appliances, and sensors are all integrated in an intelligent network.

Peer-to-Peer (P2P) networks enable users to directly share digital content (such as audio, video, and text files) as well as real-time data (such as telephony traffic) with other users without depending on a central server. Although originally popularized by unlicensed online music services such as Napster, P2P networking has recently emerged as a viable multimillion dollar business model for the distribution of information, telecommunications, and social networking. Written at an accessible level for any reader familiar with fundamental Internet protocols, the book explains the conceptual operations and architecture underlying basic P2P systems using well-known commercial systems as models and also provides the means to improve upon these models with innovations that will better performance, security, and flexibility. Peer-to-Peer Networking and Applications is thus both a valuable starting point and an important reference to those practitioners employed by any of the 200 companies with approximately $400 million invested in this new and lucrative technology. - Uses well-known commercial P2P systems as models, thus demonstrating real-world applicability. - Discusses how current research trends in wireless networking, high-def content, DRM, etc. will intersect with P2P, allowing readers to account for future developments in their designs. - Provides online access to the Overlay Weaver P2P emulator, an open-source tool that supports a number of peer-to-peer applications with which readers can practice.
