XMPP: The Definitive Guide: Building Real-Time Applications with Jabber Technologies

by Peter Saint-Andre, Kevin Smith, Remko Tron on, Remko Tronon

Overview

This practical book provides everything you need to know about the Extensible Messaging and Presence Protocol (XMPP). This open technology for real-time communication is used in many diverse applications such as instant messaging, Voice over IP, real-time collaboration, social networking, microblogging, lightweight middleware, cloud computing, and more.

XMPP: The Definitive Guide walks you through the thought processes and design decisions involved in building a complete XMPP-enabled application, and adding real-time interfaces to existing applications. You'll not only learn simple yet powerful XMPP tools, but you'll also discover, through real-world developer stories, how common XMPP "building blocks" can help solve particular classes of problems.

With this book, you will:

• Learn the basics of XMPP technologies, including architectural issues, addressing, and communication primitives
• Understand the terminology of XMPP and learn about the wealth of XMPP servers, clients, and code libraries
• Become familiar with the XMPP concepts and services you need to solve common problems
• Construct a complete business application or real-time service with XMPP

Every day, more software developers and service providers are using XMPP for real-time applications, and with the help of XMPP: The Definitive Guide, you can, too.
