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.

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.
