Increasing scope for circuit switching in the optical Internet

Abstract

This paper points out the benefit and scope of circuit switching in the future optical Internet. Given the increasingly excessive energy consumption by IP-based Internet routers which may lead to a constraint on Internet growth, the profile of Internet traffic and the high utilization achievable by dense wavelength division multiplexing, a conclusion can be made that efficient design of telecommunications network will be based on increasing the role of circuit switching in the future Internet. © 2009 IEEE.
