TL;DR: This work demonstrates IP-over-DWDM networking as "alien-wavelength" over Embratel's existing DWDM infrastructure, with robust transmission, and fully functional standards-based OAM&P.
Abstract: We demonstrate IP-over-DWDM networking as "alien-wavelength" over Embratel's existing DWDM infrastructure, with robust transmission, and fully functional standards-based OAM&P. While the router interface is LANPHY based, OAM&P is achieved via a G.709 wrapper.

TL;DR: This chapter reviews the architecture and optical transport of metro networks, which have evolved to meet the demand of various applications and services, including discussions of the evolution of network architecture, physical building blocks of the WDM network layer, requirements of network automation, and convergence of packetized IP with traditional TDM traffic.
Abstract: Publisher Summary This chapter summarizes the innovation in network architectures and optical transport that has enabled metropolitan networks to meet the diverse service needs of enterprise and residential applications, and cost-effectively scale to hundreds of Gb/s of capacity, and hundreds of kilometers of reach Metropolitan networks operate in the environs of a major city, transporting and managing traffic to meet the diverse service needs of enterprise and residential applications Typically, metro networks have a reach below a few hundred kilometers with node traffic capacities and traffic granularity that require amplified dense WDM technology with optical add/drop, although the more economical coarse WDM technology has also been deployed A converged metro network, where Ethernet/IP services, along with the traditional time division multiplexing (TDM) traffic, operate over an intelligent WDM transport layer is increasingly becoming the most attractive architecture addressing the primary need of network operators for significantly improved capital and operational network cost At the same time, the optical layer of this converged network has to introduce intelligence and leverage advanced technolog to significantly improve the deployment and manageability of WDM transport This chapter reviews the architecture and optical transport of metro networks, which have evolved to meet the demand of various applications and services, including discussions of the evolution of network architecture, physical building blocks of the WDM network layer, requirements of network automation, and convergence of packetized IP with traditional TDM traffic, and ending with a brief perspective on the future outlook
