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 OTEs 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.

  fiber and DWDM links
• WP4 Integrated network management
• WP5 Specification and execution of tests in the
  testbed and evaluation of alternative network
  architectures.

6
OTEs DWDM Network

• A ring of 9 OADMs (Marconi PMA-32) covering
  approximately 70km.
• It is used for providing gigabit services to
  GRNET (GRNET2)

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

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.

Experiment with intelligent multiplexing
equipment II

• Sorrento Networks Gigamux equipment
• Multiplexes 2 GbE signal into an SDH OC-48
