| Meeting the challenge of the service providers with combined WDM and OTN layer Metro Edge MSPPService providers in today's telecommunication market are faced with a challenge of providing high capacity services cost effectively with the shortest lead times.
By: tzachi This white paper provides an overview of the next generation optical access platform features and capabilities in conjunction with DWDM and OTN layer. The main emphasis will be made on benefits of the OTN layer as the consolidation layer for existing and next generation access networks such as the packet optical network, carrier Ethernet and the traditional SONET/SDH networks which remain relevant today for many service providers and their customers. Evolving trends Metro access networks are becoming more fiber oriented towards the end user requiring different types and capacity of traffic mixes with increasing popularity of Ethernet/data services. As the data traffic continues to grow, traditional SONET/SDH networks that were primarily designed for TDM traffic and low granularity E1/T1 rates are insufficient to support the new demands of Ethernet networks. The fiber capacity utilization has also become a major consideration for providers to reduce their overhead costs. This lead to an increasing use of wavelength division multiplexing (WDM) enabling 88+ channels of traffic to pass on different spectrally separated wavelengths over the same fiber infrastructure. The WDM layer enables most effective utilization of the existing fibers rather than investment in new construction of a new physical layer. As a result of the growth trends, a new Optical Transport Network (OTN) layer evolved over WDM network enabling more efficient convergence of traditional SONET/SDH and new data services. The OTN layer is designed to for highly effective mapping of different protocols and rates into the same 10G uplink pipe providing high bandwidth capabilities, low heat dissipation, compact rack space requirements, and comparatively low cost. Furthermore, OTN infrastructure enables transport over longer distances with less regeneration sites by utilizing forward error correction (FEC) mechanism embedded within the OTN layer. Thus, the OTN layer forms the most efficient and cost effective Multi Service Provisioning Platform (MSPP) over WDM infrastructure. The Next Generation networks - MSPP MSPP enables service providers to offer customers new bundled services at the transport, switching and routing layers of the network, while also dramatically decreasing the time it takes to provision new services and improving the flexibility of adding, migrating or removing customers. These provisioning platforms allow service providers to simplify their edge networks by consolidating the number of separate boxes needed to provide intelligent optical access. Thus drastically improve the efficiency of networks for transporting multiservice traffic. The MSPP platforms also reduce the number of network management systems needed, and decrease the resources needed to install, provision and maintain the network (Network World).
