Evolution To Optical Packet Transport
Transport networks are evolving from TDM to carry packets more efficiently. This evolution takes advantage of a range of options to deliver all-IP services, leading to Full Service Broadband: the delivery of multiple services over any bearer, to any client device. This paper outlines the role of transport options. Network operators have consistently delivered major network re-engineering to cope with the challenge that traffic grows much faster than revenue. As proof of their progress, if a Boeing 747 aircraft had reduced in price, since its commercial launch, at the same rate as bandwidth has done in the same period, the 747 would now cost the same as a pizza.
