Main WP4 objectives are the implementation, integration and experimental validation of the STRONGEST’s reference network architecture for new metro and core networking solutions designed in WP2 and WP3. In particular, WP4 will focus on two innovative and evolutionary networking approaches:

• Medium-Term networking solutions based on the introduction of a PCE -based architecture for efficient inter-domain inter-carrier path computation in multi-layer GMPLS-controlled transport networks such as hybrid wavelength switched optical networks (WSON) and connection-oriented packet transport networks (e.g MPLS-TP) for Ethernet service delivery.
• Long-Term networking solutions based on new optical metro and core switching nodes. For the metro domain solutions will support enhanced network dynamics and finer (sub-lambda) BW granularity while for the core nodes will achieve scalability to multiple tens of Terabit throughput per node with best cost and energy efficiency
