What is the 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
  communities
• Open forum 250 member companies
• international
• carriers
• component and systems vendors
• testing and software companies
• Mission To foster the development and deployment
  of interoperable products and services for data
  switching and routing using optical networking
  technologies

OIF Focus

• Low-cost Scaleable Optical Internetworking
• IP-Over-Switched Optical Network Architecture
• Physical layer
• Low-cost optical interfaces between networking
  elements
• Standard device level electrical interfaces for
  low-cost systems
• Control layer interoperability between data and
  optical layers
• Dynamic configuration using IP signaling and
  control mechanisms
• Accommodate legacy network under the new physical
  and control layer mechanisms

OIF StructureTechnical Committee 6 Working
Groups

• Carrier
• Requirements and applications
• Architecture
• Services, network requirements and architectures
• Signaling
• Protocols for automatic management of optical
  connections
• OAMP (Operations, Administration, Maintenance
  and Provisioning)
• Network management
• Physical and Link Layer
• Equipment and subsystem module interfaces
• Interoperability
• Interoperability testing

5
Output from OIF

• Implementation agreements, based upon
• Carrier groups requirements
• Existing standards and specification when
  available
• New solutions when necessary
• Interoperability testing procedures
• Ensures compliance to implementation agreements
  and ultimately interoperable products and
  networks
• Input into other standards bodies
• Formal liasons in place with numerous other
  organizations (e.g. ITU, IETF. Complete list in
  back-up slides)

OIF Process for Generating Implementation
Agreements

• Framework provided by Working Group structure
• Working groups establish consensus-driven
  projects to focus contributions
• Progress driven by member contributions
• Posted on OIF website
• Basis for activities at quarterly technical
  meetings
• Formal voting process for reaching Implementation
  Agreements
• Two step process
• Straw ballot passes with simple majority
• Principal ballot passes with 2/3rds majority
• Process enables open debate, incorporation of
  comments
• Formal votes at each step
• One vote per member company

OIF Activities Physical Layer

• Business Need
• Lower equipment costs through interface
  agreements that reduce customization
• Key Projects
• Internal system interfaces
• System/Physical Interface (SPI)
• SPI-3, SPI-4 complete for 10G
• SPI-5 in progress for 40G
• Serializer/Deserializer-Framer Interface (SFI)
• SFI-4 complete for 10G
• SFI-5 in progress for 40G
• Low cost premises equipment interfaces
• Very Short Reach (VSR)
• VSR-1, VSR-2, VSR-3, VSR-4 complete for 10 Gb/s
• VSR-5 in progress for 40 Gb/s
• Footprint specification for tunable lasers in
  progress

OIF Activities Control Layer Switched Optical
Networks

• A switched optical network is an optical network
  in which connections can be created using
  switching control technology.
• The OIF is among the organizations working on the
  interfaces to enable controllers to work together
  to perform this function

9
OIF Activities Control Layer

• Business Need
• Lower operations costs through automation of
  routing optical circuits
• Key Projects
• User-to-Network Interface enables client
  equipment to request a service across optical
  networks
• UNI 1.0 complete for SONET circuits
• 25 vendor interop. Demonstratation at Supercomm
  in June, 2001
• Built upon protocols from IETF
• Also completed Call Detail Records to support
  billing with UNI 1.0
• UNI 2.0 in progress to add other features
• Network-to-Network Interface enables optical
  networks to interact to deliver an end-to-end
  service
• NNI 1.0 in progress
• Targeting 1H03 for interoperability demonstration

Why do service providers care about optical
control plane interfaces?

• Intelligent control plane, in general, lowers
  operating costs
• Automatic discovery of elements, capacity and
  connections
• Automatic routing and recovery of circuits
• Improved survivability against complex failures
• Standardized control plane interfaces enable
• Wider adoption of control plane capabilities
• Multi-vendor/carrier interoperability
• New dynamic optical services with customer
  control
• Plug and play introduction of new
  vendors/technologies
• In advance of control plane deployment, service
  providers will continue to rely on centralized
  management systems

11
OIF control plane work vs. other organizations

• Internet Engineering Task Force (IETF)
• Community of individuals
• Generating tool box of protocols
• International Telecommunications Union
• Formal organization for establishing global
  standards
• In progress of developing comprehensive standards
  for Automatic Switched Optical Network
• Some overlap among OIF, IETF, ITU
• Healthy competition is evolving to cooperation

Summary

• OIF brings together professionals from the data
  and optical worlds
• OIF is addressing issues important to carriers
  and their customers
• Control plane work is progressing well in OIF in
  collaboration with other organizations like the
  IETF and ITU
