The first steps are focused on Connectivity services managed through a well defined Service Management System (SRV) described. Each connectivity service is designed with specific attributes including: Service Access points (UNI), throughput (x Gbps), end-to-end latency (y ms), time interval [T 1,T 2 ] GMPLS based control protocols, Timed based PCE, Network Resource Scheduler with Carrier Switches and Wavelength Cross-connects as connection services are based on Ethernet Virtual Circuit over Wavelength connections: Provisioned: through NMS with automated network Operations through MTOSI 2.0 (triggered by SRV) Signaled: RSVP-TE provides dynamic E2E guaranteed QoS on two routing areas 10
