Object-oriented (OO) technology is an integral part of computer communications and multimedia service provisioning. Covering all areas related to OO programming in telecommunications applications, this book offers both theoretical and practical aspects of OO technology. Readers will find comprehensive coverage is included on broadband, intelligent networks, and machine independent code.

Iakovos Venieris is the editor of Object Oriented Software Technologies in Telecommunications: From Theory to Practice, published by Wiley.

Fabrizio Zizza is the editor of Object Oriented Software Technologies in Telecommunications: From Theory to Practice, published by Wiley.
