TMCnet is republishing, on their website, articles I originally wrote for my monthly column, "Next Wave Redux", that appears in Internet Telephony Magazine. Here's from the April 2008 column:
In the late 1980s and through the 1990s the telecom industry defined and then adopted standards for the “Intelligent Network” (IN). The objective was to make it easy to create and deploy new applications and new services. More recently the industry has defined various next generation networks, most notably the IP Multimedia System (IMS). Besides convergence economies (all services on IP), the objective is to facilitate the rapid development and deployment of new applications and new services. Sound familiar? Unfortunately, it’s not going to work any better the second time around.
