The deployment of WDM technology in metropolitan area networks has moved the bottleneck from capacity to data processing at the network nodes. The data circulating in all wavelengths are converted from optical to electrical for being processed, thus increasing considerably the system's cost and complexity. Abolishing the SONET paradigm, new data control mechanisms are designed for interconnected WDM metro rings, alleviating the required processing and pushing it to the network edges. Moreover,

The proposed scheme has been implemented in hardware for a prototype that supports a total of 1.2Tbps metro traffic, and its design is described in the current paper.
