GRNET activities on Optical
Networking
Dimitrios Kalogeras
Summary
OTE-WAVE
 Test bed evaluating state of the
art optical multiplexing
equipment

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.

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)
OTE-WAVE test bed
Integrated Network Management

To adapt and in-field test an InterTechnology 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



Fault Management



Enables single point access to integrated
provisioning tasks
End-to-end views of connections and their
underlying infrastructure
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.
