Packet-Optical Transport Network Transformation for Emerging Services
The explosion of packet-based services and applications is spawning a new generation of transport products and networks using packet-Optical Transport. The principle strength of packet-optical transport is in leveraging embedded SDH/SONET network infrastructure, operations and expertise with a new breed of products that can gracefully migrate toward 100 percent packet traffic. These packet-optimized transport networks have the scale, operations, resiliency, and performance characteristics to meet the rigorous demands of emerging consumer and business applications. Packet-optical transport is enabled by converging TDM, packet and WDM technologies. Standards developments for connection-oriented packet transport also play a major role in assuring robust transport performance for packet traffic. Packet-optical transport is a powerful network transformation tool for operators migrating toward packet services from their current SDH/SONET base.
