Conclusions
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
