2 Comnet 2001 Tutorial Switch Control WG Simon Crosby Cplane MSF Organization MEGACO Brian Rosen Marconi Board of Directors 11 People Technical Committee Dave McDysan WorldCom Marketing Awareness Committee Carol Waller Marconi Liaison Committee Larry Gabuzda Lucent Media Control WG Petros Mouchtaris Telcordia Architecture WG Mark Klerer Nortel Interoperability WG Open Management Framework WG Avri Doria Nortel GSMP Open
3 Comnet 2001 Tutorial 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
4 Comnet 2001 Tutorial 1999 Accomplishments Media Gateway control requirements input to IETF/ITU-T MEGACO/H.248 Based switch control on IETF GSMP Adopted concept of switch partitioning Completed Straw Ballot of Release 1 Architecture Document Established Interoperability Working Group
5 Comnet 2001 Tutorial 2000 Accomplishments Completed Final Ballot of Release 1 Architecture Document Final Ballot for Switch Control (GSMP) Co-hosted First MEGACO/H.248 Interoperability Event in August at UNH Established Management Framework Working Group Drafted Implementation Agreements for MEGACO/H.248
6 Comnet 2001 Tutorial Overall 2001 Objectives Release 2 Incremental Architecture Documents – Application/ Management Plane – Extensions in support of Mobility – Extensions to support IP, MPLS Media Control Implementation Agreements – MEGACO Profiles (Access, Trunking, Residential) – MEGACO Package (CAS) – MGC-MGC Protocols (BICC, SIP-T)
7 Comnet 2001 Tutorial 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 Comnet 2001 Tutorial 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 Comnet 2001 Tutorial Logical MSF Architecture
10 Comnet 2001 Tutorial 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
12 Comnet 2001 Tutorial 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 Comnet 2001 Tutorial Media Control Functions and Interfaces IP or ATM Network Residential Gateway Access Gateway Trunking Gateway Trunking Gateway Media Gateway Controller (MGC) Media Gateway Controller (MGC) PBX PSTN SIP-T, BICC, H.225 PSTN Media (VoIP, VoATM, TDM) Signaling MEGACO/H.248 SS7, ISUP SS7, ISUP POTS, BRA, SIP, H.323 ISDN, CAS MEGACO/H.248
14 Comnet 2001 Tutorial 14 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 Detailed Media Control Charter
15 Comnet 2001 Tutorial 15 MEGACO/H.248 Work Items CAS Package (Added as a new work item) –Draft 2/01 –Straw ballot 5/01 –Final ballot 8/01 Two implementation agreements currently under development for MEGACO/H.248 –MEGACO/H.248 Profile for Access Gateway/MGC –MEGACO/H.248 Profile for Trunking Gateway/MGC Draft implementation Agreements available now –Straw ballot 5/01 –Final ballot 8/01 MEGACO/H.248 Profile for Residential Gateway/MGC –TBD Media Control Schedule
17 Comnet 2001 Tutorial 17 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? Media Control Schedule (cont.)
18 Comnet 2001 Tutorial 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 Comnet 2001 Tutorial Switch Control Protocols and Interfaces Switch Controller Physical Switch Logical Partitions FR, ATM, MPLS, CES Switch Partition Management Interface Switch Controller Switch Controller Switch Controller Multiservice Switch FR, ATM, MPLS, CES General Switch Management Protocol (GSMP)
20 Comnet 2001 Tutorial 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.
21 Comnet 2001 Tutorial Management Framework Charter Management for Media and Switch Control Components Initial Focus on MIB for Partition Management of GSMP-Controlled Switch Next Major Efforts – Partition Management of a MEGACO Controlled Media Gateway – Partitioning of Virtual Routers
23 Comnet 2001 Tutorial Management Framework Schedule Partitioning MIB – Straw Ballot – 6/01 – Final Ballot – 9/01 General Partitioning Framework – Straw Ballot –9/01 – Final Ballot – 12/01 MIB/PIB for MG & MGC management – TBD MIB/PIB for partitioned MG (w/ Media Control) – TBD MIB/PIB for partitioning Router – TBD
24 Comnet 2001 Tutorial Interoperability Three stage of interoperability testing – 1. Non-published Early Development Testing Objective is clarifying interpretations of protocol specifications as related to overall MSS requirements – 2. Public Bake Off against MSF IAs Overall system integration configuration – 3. Conformance/Compliance Testing MSF “Stamp of Approval” To Be Determined
25 Comnet 2001 Tutorial 2001 Interoperability Plans MEGACO/H.248 Interoperability Event co-sponsored with ISC 8/2000 at UNH Next MEGACO/H.248 Interoperability Event targeted for Jan/Feb 2001 Plan to Sponsor MGC-MGC Interoperability Events Plan to Sponsor GSMP Interoperability Events
