Abstract

Next generation metro aggregation systems are expected to use integrated lambda, circuit and packet switching platforms. We analyzed a typical Tier 1 aggregation scenario using a converged transport platform offering OTN, MPLS-TP and lambda switching. Vertical integration (multiple transport technologies) and horizontal integration (multiple service types) yielded about one third savings over a traditional L3 over DWDM approach. The number of wavelengths needed was roughly halved. The usage of hybrid interfaces which allow sharing the wavelength between OTN and MPLS services leads to additional savings which will increase as the line rate shifts from 10G to 40G and 100G.
