The ip backbone: transport network convergence look for IP/GigE/DWDM

摘要

To reduce customer chum, as well as increase subscriber penetration/satisfaction and revenues, the transport network is evolving into a highly reliable, intelligent, converged Internet protocol/Gigabit Ethernet/dense wavelength division multiplexing (IP/GigE/ DWDM) network for the delivery of triple-play video, voice and data services. These network changes are allowing cable operators to reduce the time to market of new services, lower network capital costs, reduce network complexity and operational expenses, and most importantly, allow operators to effectively compete and maintain their leadership position in the broadband services market.
