Launched in April 1998 with the main objective to foster the
development of low-cost and scalable internet using optical
technologies
The only industry group bringing together professionals from
the data and optical communities
Open forum: 130+ member companies
• Carriers
Component and systems vendors
• Testing and software companies
OIF Mission
To foster the development and deployment of interoperable
products and services for data switching and routing using
optical networking technologies

OIF World Interoperability Demo 2004 (I)


Interop Area 1: Fast, automatic and dynamic end-to-end
optical multi-vendor connection management
Demo objectives
• Dynamic resource allocation by a standardized control
plane
• Automatic provisioning by client equipment via UNI
interface (Switched connections) or by management
system (Soft permanent connections)
• Automatic multi-domain provisioning via E-NNI interface
 Carrier perspectives and benefits
• Enabling of advanced, customizable services
• Enabling of multi-vendor interoperability
• Simplification of node/network management
• Effort and time reduction for end-to-end service
provisioning



Interop Area 2: Efficient Ethernet transport over
SONET/SDH (GFP, VCAT, LCAS)
Demo objectives
• Generic Framing Protocol: mapping Ethernet over
SONET/SDH
• Virtual Concatenation: flexible bandwidth
allocation and diverse paths
• Link Capacity Adjustment Scheme: hitless
bandwidth modification
 Carrier perspective and benefits
• Efficient use of existing SDH infrastructure for offering
Ethernet data services
• Possibility of advanced Ethernet connectivity
• Packet data with SONET/SDH grade reliability and
multiple QoS

Conclusions
Significance of the Achievement
 First time ever in the industry to conduct world wide multi-carrier
interoperability testing
- Carrier’s close involvement and strong support is a key milestone
towards deployment of automatically switched optical networks
- Lays the foundation for future testing methodology and demo
infrastructure
 Successful control plane and data plane integration and interworking
- validates OIF’s Implementation Agreements and ITUs Standards
- demonstrates that standardization clearly facilitates multi-vendor,
world-wide interoperability
 Successful validation of multi vendor interoperability on Ethernet
service adaptation (GFP, VCAT/LCAS)
- Demonstrates the possibility to offer new services over legacy
network in a cost-effective way
Conclusions




Large scale, world wide OIF interoperability testing is
progressively validating the maturity of NG-SDH and IP over
Optical technologies
The strong presence of Carriers and Vendors in OIF ensures
proper setting of requirements for next generation
IP/optical networks with advanced control plane
The valuable effort of Carriers and Vendors in OIF is
accelerating the development of easy-to-deploy solutions
Further cooperative effort is needed by all Standardization
Bodies to make available completely standardized
solutions
