Abstract

In the 1970s - before dense wavelength-division multiplexing (DWDM), Google, Facebook, iPhone, and Skype - we had a telephone network based on circuit-switching technology for primarily real-time services (voice) and also for a very small traffic volume of data. This network provided reasonable voice quality, reliability, availability, and accessibility to customers. The telephone exchanges of the '70s somehow could maintain call state information, which is considered "unscalable" by many in the 21st century despite the tremendous technological advances in chip technology of the last 40 years. Furthermore, according to the recent Cisco White Paper [1], "The sum of all forms of video (TV, VoD, Internet, and P2P) will account for close to 90 percent of consumer traffic by 2012." This immediately leads to the question: if we are going to have fundamentally similar services, why shouldn't we consider increasing the use of networking concepts and solutions we had in the '70s? © 2006 IEEE.
