Design and Implementation of Aggregation Platform for Extended Ethernet Transport and Services

This paper describes an industry best practice of edge routing and switching platform development for extended high-speed Ethernet transport and services. This is the first system designed to provide integrated 10Gb/s LAN/WAN PHY and OTN G.709 digital wrapper based Ethernet transport over wide area networks. Built on top of PHY device´s comprehensive clock generation and recovery circuitry, it also supports the Synchronous Ethernet with the ability to distribute frequency through Ethernet ports and external timing interface. In addition, this optical networking oriented platform is augmented with Automatic Laser Shutdown capability for laser safety assurance. Our initial evaluation indicates that this aggregation platform can cost-effectively extend the converged IP over DWDM/OTN architecture from the core to the edge layers. Its scalable and optimized architecture design has great potential for advanced Metro/Carrier Ethernet feature expansion.
