About OIF: 

About OIF Launched in April of 1998 with an objective to foster development of low-cost and scaleable internet using optical technologies The only industry group bringing together professionals from the data and optical worlds Open forum: 100+ member companies International Carriers Component and systems vendors Testing and software companies Our Mission To foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies

Output from OIF – Implementation Agreements: 

Output from OIF – Implementation Agreements 35 agreements published to date Applications include: Control plane interfaces User-to-Network (UNI), Network-to-Network (NNI), Security & Billing Intra-office Optical interfaces Very Short Reach (VSR) 10Gbps & 40 Gbps Tunable Lasers Assembly and Control Intra-system Electrical interfaces Serializer/Deserializer-Framer interface (SFI), Physical-Link Layer device interfaces(SPI), Fabric-to-Framer interface VSR SPI SFI E/O Tx SER DES Framer Link Layer (Packet & Cell Protocols) VSR SPI SFI E/O Tx SER DES Framer Link Layer (Packet & Cell Protocols)

Outline OIF Overview Control Plane Interoperability Demonstrations Current Work and Future Directions

2005 - Second Worldwide Demonstration: 

2005 - Second Worldwide Demonstration World's leading optical technology carriers and suppliers 7 carriers and 13 vendors invested significant time and resources to complete the demonstration Collaborating to build a global optical network delivering Ethernet services Global Reach 3 Continents, 6 Countries Trans-Atlantic, Trans-Pacific network connection set-up

OIF Interoperability Labs: 

OIF Interoperability Labs Beijing, China Berlin, Germany Musashino, Japan Lannion, France Middletown, NJ-USA Waltham, MA-USA Torino, Italy

Technical Highlights: 

Technical Highlights The network consists of over 70 nodes from 13 vendors in the 7 carrier labs Equipment includes Ethernet switches, routers, MSPPs, SONET/SDH cross-connects, OADMs, ROADMs Ethernet Services demonstrated: Ethernet Private Line service Enabled by OIF optical control plane Virtual Ethernet services (Virtual Private Line, Virtual Private LAN, Internet Access/Virtual Trunking) Enabled by VLAN tags

Major Accomplishments: 

Major Accomplishments Multi-layer call/connection control of UNI-N devices Orchestrates actions between client and server layers Controls Ethernet adaptation using GFP-F/VCAT/LCAS Creation of end-end calls and connections across: Multiple data plane layers Multiple vendors’ equipment Multiple carrier labs The major features (1) Ethernet over SONET/SDH adaptation and (2) distributed optical control planes have each been demonstrated before However, this is the first event bringing both together in an integrated fashion on a global scale

Feedback from OIF/ASON Prototyping Work: 

Feedback from OIF/ASON Prototyping Work Prototyping of ASON routing principles Participation by OIF members in IETF Joint Design Team IETF Routing Evaluation draft (RFC 4652) Followed up by IETF Solutions draft, in progress Example Areas: Flexible distribution of control and data plane elements Modified SONET/SDH bandwidth accounting

Flexible Distribution of Control and Data Plane: 

Flexible Distribution of Control and Data Plane Allow one Routing Controller to advertise for multiple Data Plane Nodes Result: Supported by adding Local and Remote TE Router IDs to the Link State Advertisement see draft-ietf-ccamp-gmpls-ason-routing-ospf-03.txt routing NE LSR Model routing ASON Model

Modified Bandwidth Accounting: 

Modified Bandwidth Accounting Under certain conditions, overall bandwidth does not reflect ability to support connections e.g., enough timeslots but not contiguous for a large signal type Result: advertise actual availability for connections at each signal type if appropriate see draft-ietf-ccamp-gmpls-ason-routing-ospf-03.txt
