In this paper, the authors propose a more cost-efficient alternative to current transport network technologies (SONET/SDH) based on the high-bandwidth transport and deterministic performance of the optical circuit technologies (i.e., WSON) along with the efficient aggregation and statistical multiplexing of a packet transport technology (i.e., MPLS-TP) to support IP and Ethernet services. The purpose is to achieve cost reductions, simplified operations and flexible scalability in transport networks. They present the architectural design, implementation and the performance evaluation of the forwarding capabilities of a MPLS-TP/PWE3 node with integrated 10Gbps tunable DWDM transponders, extending the GMPLS-enabled WSON transport network of the ADRENALINE Test-bed. The node has been implemented using commercial off -the-shelf hardware and the forwarding engine has been implemented using open source software.
