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
