Demystifying Optical Ethernet Networks

摘要

The TDM-to-packet network transformation has been underway in transport/telecommunications networks for some years now, fueled primarily by two trends: (a) the advent of triple-play (voice, video, data) for enterprise and residential customers and, lately, the explosion in video and mobile data services, and (b) the evolution in both packet- and transport-network equipment. In this regard, there have been rapid advancements to make packet technologies, such as IP and Ethernet, more "circuit-like", and to make transport technologies and equipment more dynamic and, thus, "packet friendly."
