Steve Joiner, Technical Committee Chair John McDonough, Member OIF Board of Directors Optical Internetworking Forum

What is the OIF? Why the OIF? Organization of Working Groups Possible Interaction OIF / ITU-T Summary

What is OIF? Launched in April of 1998 Open forum: 340+ members including many of the worlds leading carriers and vendors The only industry group bringing together professionals from the packet and circuit worlds Addresses key issues in a timely fashion that are not being addressed elsewhere Mission: To foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies

Output from OIF Develop implementation agreements among its members Standalone documents representing broad agreement among members OIF implementation agreements assure customers of consistent functionality and interoperability Provides input into existing standards bodies and influences the development of standards

Technical Committee Six Working Groups Architecture Services, network requirements and architectures Carrier Requirements and applications Signaling Protocols for automatic setup of lightpaths OAM&P (Operations, Administration, Maintenance and Provisioning) Network management Interoperability Interoperability testing Physical and Link Layer Equipment and subsystem module and optical interfaces

Areas for Standardization Network Architectures Including Optical/DWDM technologies Design for Data services Physical layer transmission technologies Higher line rates Low Cost Short Reach Interfaces More flexible framing structures Layer 2 and 3 Transport and Encapsulation New data centric protocols to transport Collapsed protocol stacks Network Management and Control Simplify and automate management Fast, flexible & efficient provisioning

OIF and Standards Bodies OIF submissions perform two functions: Request standardization of specific OIF recommendations Provide informational documents to the target standards group Established Liaisons With: ANSI T1 IETF ATM Forum IEEE 802.3ae 10 Gigabit Ethernet Network Processor Forum ITU-T SG 15

OIF - Optical Internetworking Forum UNI Optical User to Network Interface Based upon GMPLS Signaling Protocols Intra-carrier NNI work underway Very Short Reach Optics (VSR) 10G and 40G 12 fiber parallel, 4 fiber parallel, 850nm serial, 1310nm serial Internal System and Chip Interfaces SPI - System Packet Interface SFI - SERDES Framer Interface

PLL Working Group Adopted Packet Over SONET/SDH link layer Interfaces internal to network elements Benefits to system vendors and technology vendors Interface definitions lead to physical module standardization, thus lower costs Serializer/Deserializer-Framer Interfaces (SFIs) System Physical Interfaces (SPIs) 10G and 40 G Interfaces between network elements Very Short Reach Interfaces (VSR) Parallel optics solutions for low cost 10 G interfaces Link Layer (Packet and Cell based Protocols) Rest of the System SONET/SDH Framer PHY Layer SERDES E/O Transceiver Transmission Media SPI SFI

PLL Agreements 10Gb/s VSR Agreements VSR-1, 12 fiber x 1.25Gb/s 850nm(<300m) VSR-2, Serial 1310nm(<600m) VSR-3, 4 fiber x 2.5Gb/s 850nm(<300m) VSR-4, Serial 850nm(<300m) Electrical Interface Agreements SPI-3 OC48 System Packet Interface SFI-4 OC192 Serdes-Framer Interface SPI-4 phase 1 OC192 System Packet Interface SPI-4 phase 2 OC192 System Packet Interface PLL = Physical Link Layer

PLL Work In Progress VSR 40Gb/s Very Short Reach Optics SPI-5 40Gb/s System Packet Interface SFI-5 40Gb/s Serdes-Framer Interface TFI-5 Framer to Fabric Interface SFI-4 Phase 2 - OC192 Serdes-Framer Interface with narrower data paths. Tunable laser – non-optical interface IA

Signaling Working Group Define Signaling protocols used between optical network elements Enables clients to establish optical connections Re-uses work from other standards bodies UNI 1.0 complete Now in public domain as implementation agreement. Future Project UNI 2.0 started November 2001 Intra-carrier NNI started November 2001

UNI 1.0 Functions SONET/SDH Connection Signaling Establishment Deletion Status exchange Automatic topology discovery Automatic service discovery SONET/SDH Transport

UNI 1.0 Protocol Components Connection Signaling RSVP or CR-LDP with GMPLS extensions Additional UNI Objects/TLVs Service Discovery & Neighbor Discovery Link Management Protocol (LMP) Additional UNI TLVs UNI Transport Out of band - via IP transport (eg Ethernet) may use separate wavelength In Band - via SONET/SDH DCC

UNI 1.0 and GMPLS Relationship Generalized Multi-Protocol Label Switching (GMPLS) MPLS was designed to support forwarding of data based on packet or cell boundaries Extensions to MPLS to include Time Division (SONET/SDH Add/Drop Multiplexers), wavelength (optical lambdas), and spatial switching Gives MPLS a way to identify time slots or wavelengths UNI 1.0 uses GMPLS formats

UNI Interoperability Trials UNI Interoperability trials - 25 vendors demonstrated UNI interoperability at SUPERCOMM - Atlanta, GA; June, Vendors Agilent Avici Alcatel Ciena Cinta Cisco Coriolis Corvis Geyser Huawei Metro-Optix Lucent Nortel ONI Optisphere Optivera Redback Spirent Sycamore Tellium Tenor Turin Village Zaffire

Objective of OIF / ITU-T interaction The OIF does not want to duplicate other work. Our membership is substantially different in makeup to the ITU membership The OIF will debate in its forum the pros/cons of different approaches. Frequent and close communication will insure that the diversity of objectives and solutions will be heard and lead to the best solutions.

OIF Summary Brings together professionals from the data and circuit worlds Addressing key issues important to carriers and vendors Nine technical documents ratified as Implementation Agreements Optical module interface standards will allow industry to gain needed economies of scale Future work: (NNI) Network to Network Interface; richer functionality UNI 2.0; billing for UNI.
