  3. MSF Technical Committee Charter • Overall system and life-cycle view • Requirements, architecture, protocol specification, implementation details, facilitate interoperation • Leverage other standards bodies and activities wherever possible • Liaison with other standards bodies to communicate requirements, define protocols, co-sponsor events

  7. Overall 2001 Objectives • At least two Media Control Interoperability Events • Switch Partitioning Documents • MIB, Requirements • Technical Reports • Vendor White Papers • Liaisons to IETF, ITU, ISC, Others

  8. Architecture Charter • Define overall terminology and framework for the MSF, building upon Release 1 architecture document • Release 2 • IP Support • MPLS Support • Mobility Support • Application Plane Architecture • Statistical Switch Partitioning (if possible)

  9. Application Standard IN/Signaling APIs, Interfaces, and Protocols Plane ... Control IP/MPLS Voice/SS7 ATM/SVC Plane Controller Controller Controller Switching ManagementPlane Multiservice Switching Fabric (any switching principle) Plane ... Adaptation Plane Video TDM ATM FR TCP/IP Voice External Interfaces/ Standard Physical and Logical Interfaces Protocols Logical MSF Architecture

  10. Release 2 Document Structure • Architectural Framework • Definitions, objectives, document structure, • Functional Architectural Framework • Separate document for IP, MPLS, Mobility, Application plane, etc. • Physical Architectural Mapping • Network Mapping w/ reference protocols • Service Example Call Flows

  11. Architecture WG Schedule • Application Plane Functional Framework • Straw Ballot 9/01 • Final Ballot 12/01 • Mobility Functional Framework • Straw Ballot 9/01 • Final Ballot 12/01 • IP/MPLS Functional Framework • Straw Ballot 9/01 • Final Ballot 12/01

  12. Media Control Working Group Charter • MG-MG Interface • Media Gateway Control (MEGACO)/ H.248 Jointly developed by IETF & ITU-T • MGC-MGC Interface • Session Initiation Protocol (SIP) or Bearer Independent Call Control (BICC) • MGC-Telephony Interfaces • SS7, ISDN, Channel Associated Signaling (CAS), etc.

  13. Media Control Functions and Interfaces SIP-T, BICC, H.225 Media Gateway Controller (MGC) Media Gateway Controller (MGC) SS7, ISUP SS7, ISUP MEGACO/H.248 Trunking Gateway Trunking Gateway PSTN PSTN IP or ATM Network ISDN, CAS POTS, BRA, SIP, H.323 Residential Gateway Access Gateway PBX Media (VoIP, VoATM, TDM) Signaling MEGACO/H.248

  14. Detailed Media Control Charter • MEGACO/H.248 • MEGACO/H.248 Profile for Access Gateway/MGC • MEGACO/H.248 Profile for Trunking Gateway/MGC • MEGACO/H.248 Profile for Residential Gateway/MGC • CAS package (new work item) • ia reference point • SIP-T • BICC • Legal Intercept (new work item) • Management Interface for MGC and MG (inviting contributions) – To be done in conjunction with management framework working group • 14

  16. Media Control Schedule (cont.) • ia reference point • BICC • BICC outline for implementation agreement (8/00) • Draft BICC Implementation Agreement (2/01) • Straw ballot BICC Implementation Agreement (5/01) • Final ballot BICC Implementation Agreement (8/01) • SIP-T • Draft SIP-T Implementation Agreement (11/00) • Straw ballot SIP-T Implementation Agreement (5/01) • Final ballot SIP-T Implementation Agreement (8/01) • 16

  17. Media Control Schedule (cont.) • Legal Intercept • New work item. • Invite contributions • Dates TBD until next meeting • Management Interface for MGC and MG (inviting contributions) • No progress to date. • Can the management group take it over? • 17

  18. Switch Control Charter • General Switch Management Protocol (GSMP) • Specified jointly by MSF and IETF • Supports ATM, FR, MPLS connection establishment, termination, and status checking • Also provides means to configure interworking, where applicable • Circuit Emulation a planned future work item • Future scope/charter TBD • Optical switching? • Distributed router?

  19. Switch Control Protocols and Interfaces Switch Controller Switch Controller Switch Controller Switch Controller General Switch Management Protocol (GSMP) Logical Partitions Switch Partition Management Interface Physical Switch FR, ATM, MPLS, CES FR, ATM, MPLS, CES Multiservice Switch

  20. Switch Control Schedule • Straw Ballot GSMP (without CES) • Approved 1/01 • Final Ballot GSMP (with CES) • February, 2001 • CES additions to GSMP – TBD? • Issue: No MSF contributions or member support for this effort. No effort in IETF either.
