Summary: The IP infrastructure is still work in progress
Review: We have spent the better part of the last seven years trying to create a nationwide infrastructure to support IP services and applications. In spite of the great progress, this is still work in progress. A large question still exists. How are we dealing with the physical and security limitations of packet technologies in the wide area? Some of these early concerns were covered in my first book "IP Telephony, The integration of robust VoIP services", sponsored by Hewlett-Packard / Agilent Technologies and published by Prentice-Hall. But that was only the beginning...there is a lot more work that needs to be done before we can safely say we have hit the target of ubiquitous "seamless integration" of applications and services...and let's not forget that in the end, we will have to address the manner in which we access and manipulate large scale and distributed data across the wide area. In my second book I cover SIP, H.323, SCTP, MGCP, H.248 and other IP protocols with interoperability test cases and call flows. Understanding the enormity of protocol interoperability is only half the battle. The other half is choosing the architecture that will deliver the performance and product features. The new battlefield the will determine the feasibility of a lot of new network designs will be around data access and manipulation. IT systems and network systems tend to want to blend into each other, but can it be done with the state of the art in data base design? More to come...Enjoy the book. Bill
