  1. Recent Progress in ASON Technologies in the OIF Joe Berthold President – Optical Internetworking Forum

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

  3. 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 MissionTo foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies

  7. OIF Interactions with other bodies • IETF • Frequent informal liaisons on protocol issues and activities • Example: Ethernet traffic specifications • Security Aspects • ITU-T • Liaisons for exchange of documents, issue identification • Cooperative discussion on ASON-related Demos and Implementation Agreements • MEF • Recent liaisons on Ethernet-related work • Support of MEF Ethernet service characteristics in OIF UNI 2.0

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

  9. 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

  10. SuperComm 2005 booth OIF Interoperability Labs Lannion, France Waltham, MA-USA Beijing, China Berlin, Germany Middletown, NJ-USA Torino, Italy Musashino, Japan

  11. 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

  12. 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

  13. 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

  14. NE NE NE 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 routing NE LSR Model ASON Model

  15. 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

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

  17. OIF Optical Routing Activities • OIF-ENNI-OSPF-01.0 Implementation Agreement approved 01/2007 • OSPF-based Inter-domain routing within carrier network • Uses ITU-T G.7715 and G.7715.1 ASON routing requirements • Incorporates inputs from OIF Carrier WG • Documents prototyping of OSPF-based ASON routing • codepoints used for prototyping purposes • prototyping example • Points towards future incorporation of routing standards work from IETF and ITU-T

  18. OIF Optical Signaling Activities • OIF UNI 2.0 Implementation Agreement in progress • Adds MEF-based Ethernet UNI service interface • Ethernet Private Line and Virtual Private Line • MEF traffic parameters (liaison with IETF CCAMP) • Ethernet Label formats (liaison with IETF CCAMP) • Ethernet bandwidth modification • OTN and sub-STS-1 rate services • OIF E-NNI Signaling 2.0 also in progress • Ethernet support over VCAT SONET/SDH • Bandwidth modification using VCAT group resizing • Multilayer model derived from ASON work

  19.

  20. Link DB Link DB OIF Discovery Progress • Prototyping work in progress • Relies on ITU-T G.7714.1 Layer Adjacency Discovery specification • Exchange Discovery messages over J0 • Follow up with miswiring detection Neighbor Discovery 1. J0: (Node A, Port 5) 2. J0: (Node B, Port 2) Node B Node A 3. Verify Wiring 4. Verify Wiring {B.2, A.5} {A.5, B.2}

  21. OIF Security Work • Security requirements • Driven largely by input from US Dept. of Defense • For UNI, ENNI and Management interfaces • Application of IPSEC and IKE technology • Use of Syslog for event recording • Documented in multiple IAs • OIF-SEP-01.0, OIF-SEP-02.1, OIF-SMI-01.0 • Working now with IETF MPLS/GMPLS security framework design team
