GRNET activities on Optical Networking
Dimitrios Kalogeras
Summary
OTE-WAVE Test bed evaluating state of
the art optical multiplexing equipment
OTE-WAVEA 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.
OTE-WAVE participants
OTE (coordinator) GRNET (contractor) National Technical University of
Athens (contractor) University of Athens (contractor)
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
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)

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