Dynamic Bandwidth Services

Optical control plane enables-

Multivendor Service Activation

Modify bandwidth based on application needs

Improved Manageability

  • Auto-discovery
  • Auto-provisioning
  • Network is the database
  • End-to-end service management

Control plane standards accelerate interoperability

and simplify management system development

2004 OIF World Interoperability Demonstration

Interoperability of Dynamic Intelligent Optical Networks

  • Interfaces
    • O-UNI 1.0 (Optical User Network Interface)
    • E-NNI 1.0 (External Network to Network Interface)
  • Interoperability
    • Network Topology Discovery
    • Provisioning and Support of Switched High Speed Circuits

Ethernet/SONET adaptation using Generic Framing Procedure (GFP)

  • Capabilities demonstrated
    • Fast Ethernet (100 Mb/s) on a mix of SONET/SDH payload options
    • Gigabit Ethernet (1Gb/s) on a mix of SONET/SDH payload options
significance of the event
Significance of the Event
  • Industry’s first time ever worldwide multi-carrier interoperability testing
    • Carriers’ close involvement and strong support are key to the technology advancing towards industry adoption
  • Control plane connectivity built out around the world lays the foundation for future testing methodology and infrastructure
  • Successful control plane and data plane integration validates OIF’s Implementation Agreements
  • Participation of 15 industry leading vendors and 7 major carriers signifies the wide technology adoption in industry
