1. GRNET activities on Optical Networking Dimitrios Kalogeras

2. Summary OTE-WAVE Test bed evaluating state of the art optical multiplexing equipment

3. OTE-WAVE A pilot project aiming at: Facilitate awareness of state of the art optical networking technologies by using the OTE’s DWDM equipment. Adapt a system for providing integrated management for IP and DWDM networks Perform interoperability tests Explore new services through the gigabit test bed.

4. OTE-WAVE participants OTE (coordinator) GRNET (contractor) National Technical University of Athens (contractor) University of Athens (contractor)

5. OTE-WAVE activities WP1: Project Management WP2: Network design WP3: Network implementation and measurements on fiber and DWDM links WP4: Integrated network management WP5: Specification and execution of tests in the testbed and evaluation of alternative network architectures. WP6: Dissemination

6. OTE’s DWDM Network A ring of 9 OADMs (Marconi PMA-32) covering approximately 70km. It is used for providing gigabit services to GRNET (GRNET2)

7. OTE-WAVE test bed

8. Integrated Network Management To adapt and in-field test an Inter- Technology Network Management System (INMS) on top of IP/MPLS and DWDM management systems that is capable of: Providing integrated end-to-end MPLS Paths over Optical SNCs Bandwidth guarantees Alarm Reporting and Correlation Performance Monitoring and Assurance

9. Integrated Network Management II Configuration Management Enables single point access to integrated provisioning tasks End-to-end views of connections and their underlying infrastructure Fault Management Enables integrated reporting, logging and correlation of alarms to determine the root cause Fault localization and restoration (layer, managed entity responsible for the fault) Performance Management Enables the collection and processing of data from the technology NMSs in order to assess the QoS of the provided connectivity

10. Measurements on DWDM links Measurements of 10Gbps DWDM links will be performed in terms of Attenuation Polarization Mode Dispersion Chromatic Dispersion

11. Measurements on DWDM links II

12. Experiment with intelligent multiplexing equipment GRNET participated in the iGRID 2002 conference with the cooperation of Electronic Visualization Lab, University Illinois at Chicago. Streaming of digitised VR stereo signal to a remote user through gigabit network using EVL Teravision Technology.
