Optical Networking White Papers
Three Approaches to Optical Networking
Overview A lot has happened since Synchronous Optical Network (SONET) first saw the light of day. Development of the SONET standards -- and their international equivalent the Synchronous Digital Hierarchy (SDH) -- were driven, in part, by their utility as the physical layer of a proposed Broadband ISDN (B-ISDN) network whose characteristics would include the ability to merge the voice, data and video environments. Perhaps most importantly, the old notion of a telco-provided B-ISDN based on ATM has given way to that of an IP dominated "information highway" provided by a very diverse group of carriers. And just as the once dominant ATM "research program" is now seriously challenged by IP, so the conventional view of how SONET should be deployed is now under threat from the rise of commercialized wave division multiplexing. This White Paper takes a look at where optical networking is headed in an era of convergence.
