1 OPTICALINTERNETWORKINGFORUM OIF Technical Committee and Its Activities Joe Berthold, Ciena, Technical Committee Chair

2 OPTICALINTERNETWORKINGFORUM Role of Technical Committee  Develop specifications to ensure Interoperability of Optical Internetworks Charter Working Groups Approve Working Group Projects Technical work is driven by contributions

3 OPTICALINTERNETWORKINGFORUM Contributions  Technical committee work is driven by contributions 1998 - 37 contributions 1999 - 73 contributions

4 OPTICALINTERNETWORKINGFORUM Relationship to Standards Bodies  OIF seeks to leverage and complement the work of standards bodies IETF, ATM Forum for data networking standards T1 (US) and ITU for SONET/SDH and the Optical Transport Network, OTN

5 OPTICALINTERNETWORKINGFORUM Technical Committee Structure Architectural Workshop Group Rick Barry, Sycamore Networks - Chair OAM&P Working Group Curtis Brownmiller, MCI Worldcom - Chair Physical and Link Layer Working Group Sid Chaudhuri, AT&T - Chair Technical Committee Joe Berthold, Ciena - Chair Drew Perkins, Ciena - Vice Chair

6 OPTICALINTERNETWORKINGFORUM Architecture Working Group Charter  Solicits and analyzes requirements from service providers and develops an architecture to meet those requirements.  Includes concept, definition, analysis and documentation of architectural matters

7 OPTICALINTERNETWORKINGFORUM Physical and Link Layer Working Group Charter  Specifies Implementation Agreements related to physical and data-link layer interfaces between Optical Internetworking elements  Defines the transport mechanisms necessary to support OAM&P functions  Includes the concept, definition, analysis, and documentation of matters related to the interconnection of Optical Internetworking Signals

8 OPTICALINTERNETWORKINGFORUM OAM&P Working Group Charter  Develops operations, maintenance, administration and provisioning requirements, guidelines and Implementation Agreements related to Optical Internetworking including:  Planning, engineering and provisioning OAM&P processes Operations support systems

9 OPTICALINTERNETWORKINGFORUM Interoperability Focus Areas  Architectural models  Protection and restoration Architectures Interlayer Coordination  Network management  Signal interfaces between data network elements and optical network elements  System physical layer interfaces

10 OPTICALINTERNETWORKINGFORUM OIF Initial Scope Approved January 1999  The OIF’s first implementation agreement will specify a set of protocols for packet/cell based communications over optical channels utilizing SONET/SDH* framing and other protocols to be determined. *This does not preclude the use of other protocols in the future

11 OPTICALINTERNETWORKINGFORUM Simple Reference Model Optical Subnetworks Data Networking Element Open Interfaces single optical channel

12 OPTICALINTERNETWORKINGFORUM Projects: Architecture WG  Optical Internetwork Requirements and Applications  Optical Internetwork Architecture: functions and reference models  IP Transport via SONET Framed and Rate Signals through Optical Internetworks  Architectures for protection and restoration

13 OPTICALINTERNETWORKINGFORUM Projects: Physical & Link Layer WG  Develop interfaces based on POS at 155 Mb/s, 622 Mb/s, and 2.5 Gb/s  Develop a 10 Gb/s interface based upon SONET/SDH standards  Develop a lower-cost 10 Gb/s interface for intra-office data applications  Develop a system interface to physical layer modules

14 OPTICALINTERNETWORKINGFORUM Projects: OAM&P WG  None currently approved

15 OPTICALINTERNETWORKINGFORUM Physical Layer Interfaces  SONET/SDH based physical layer Interoperability with current networks Fault, performance management features Widely available components  Packet mapping: follow IETF

16 OPTICALINTERNETWORKINGFORUM Premises Interfaces Backbone Network Node Data Equipment Optical Bandwidth Management DWDM Transmission Links into the wide area network Number of high speed premises interfaces may equal or exceed number of wide area interfaces. Efficient premises interfaces essential as capacity scales

17 OPTICALINTERNETWORKINGFORUM System Interface to Physical Layer External Optical Interface System Physical Interface Physical Layer Module

18 OPTICALINTERNETWORKINGFORUM Summary  Started with simple, important choices SONET/SDH based 2.5G and below SONET/SDH based 10G  Working tougher issues in parallel Architectural models Protection and restoration Network management Low cost premises options for 10G
