When you turn on your cell phone, the first thing you see is the message looking for service. During the delay to follow your phone is busy locating the network and negotiating admission to it. This is called programming service discovery interfaces; it is not easy, but it's a prerequisite for all telecom services. This title teaches developers how to do it right. It explains and compares competing platforms: Bluetooth, Jini, Salutation, SLP and UPnP.

"Service and Device Discovery" is a complete survey of the state-of-the-art in an emerging field. Client/server architectures may not be new, but the world has changed around them. Increasingly complex networked environments and the proliferation of mobile devices create many instances where highly dynamic client/service behavior is the norm and not the exception. Service discovery protocols enable "plug and play" architectures, where services may be introduced into a network and removed at will, without configuration hassles. In addition, service discovery is an important step toward eliminating manually installed drivers, relying instead on standard interfaces to put devices in touch.
WHY SERVICE DISCOVERY?
Service discovery will make networked devices significantly less tedious to deploy and use than they are today. As a way to standardize the environments in which client/server applications are developed and used, service discovery technologies have the potential to:
* make interactions between clients and services much more dynamic
* provide software tools for developing machine-to-machine communications
* automate discovery of required services and peripherals
* reduce administrative overhead for deploying or interfacing services
* minimize re-configuration and encourage more device mobility
* build more interesting applications for networked environments
INSIDE THE SERVICE DISCOVERY FRAMEWORK, designers and programmers will learn how clients can discover needed services. How services advertise their presence. How catalogs track availableservices and garbage collection facilities rid the system of outdated information. How multicast is used to support discovery and advertisement. How to enable clients to browse and subtype services. And how to anticipate interoperability issues.
In this book, researcher and developer Golden G. Richard III:
* Condenses thousands of pages of protocol specifications to their essentials and helps you interpret predictably terse material
* Investigates all four leading protocols for service discovery
* Provides complete client and service examples in Java and C
"Service and Device Discovery: Protocols and Programming" contains fully documented source code for representative clients and services, for all four technologies, examined and explained in detail.
