Carriers and service providers have united around the concept of the Next-Generation Network (NGN). Although leveraging a broad basket of Internet technologies, the NGN is not being planned as the next-generation Internet. In its intention and architecture, it is more accurately described as Broadband-ISDN release 2.0. The NGN is hard to understand because it weaves together so many distinct issues: technology, new kinds of product, a new kind of carrier organization as well as changes in the business model, industry value chain and the shape of a converged future industry itself. This book presents a unified analysis of the complex transformation process that is taking place in the fixed telecoms, mobile telecoms, and broadcast industries and outlines strategies for success.
