•Technology-dependent line cards, packet, circuit or wavelength, where traffic is properly processed according to its native format, including:
¬Overhead management
¬Performance-monitoring protections for operations, administration and maintenance (OAM)
¬Packet classification
¬Policing
¬Scheduling
The line cards provide native traffic processing.
•This innovative demarcation between traffic processing and traffic switching eliminates the cost penalties associ- ated with technology-dependent processing performed in the switch (matrix) found in traditional transport-node architectures. Packet, TDM or WDM traffic processing resides on the relevant line cards. Gradual investment, in step with traffic requirements, is possible.
•The fully ROADM architecture provides the flexibility and scalability needed for today’s service-provider operating networks, where traffic is hard to predict, or where traffic churn is important. ROADM offers the advantages of any-to-any node support, remote configuration and reconfiguration, gain equalization, reduced truck rolls and multidegree meshed network architectures.
The concept of a single transport- aggregation platform is a breakthrough in service-provider networking. Instead of investing in several network layers to provide the required service mix, service providers can now choose one platform that delivers all services. By deploying the Alcatel-Lucent 1850 TSS-320 as a unified transport platform supporting any mix of services, service providers can:
•Simplify network operations, significantly reducing operating expenditures (OPEX) and increas- ing the network fexibility and scalability
•Lower the risk of capital expendi- tures (CAPEX) investments that may vary over time, depending on service-demand changes
•Shorten time-to-revenue for new services
