Softswitches are the wave of the telecommunications industry's future! If you want to know more, you should read this excellent book on softswitch technology as the enabling platform for next-generation packet communications -- including voice, broadband, and wireless networks. Franklin D. Ohrtman does an outstanding job of showing how softswitch technology and applications enable global service providers and carriers to optimize their networks and generate new revenue streams with new services and applications. In other words, the author illustrates how softswitch technology disrupts incumbent service providers and their vendors. He helps to identify some of the success and technological challenges of the industry based on the softswitch.
This book focuses on the metrics of performance of the emerging telecommunications infrastructure in terms of scalability, reliability, quality of service (QoS), signaling, and features. Ohrtman analyzes how softswitch technologies might meet or exceed the performance parameters of the Public Switched Telephone Network (PSTN) infrastructure (specifically Class 4 and 5 switches, in addition to Private Branch Exchanges (PBXs). He also explains how it's becoming increasingly clear that Creative Destruction takes place from an engineering perspective. The addition of an acronym list is also a nice touch.
The telecommunications industry is changing, and opportunities abound. Folks who find themselves caught up in this revolution will be delighted with this well-written and coherent account of what's changing and why. Not incidentally, they will also learn how to benefit from these changes. John Vacca
