Understanding the MSF Wayne Cutler MSF CTO & TC Chairman 2011
Who is the MSF? • Founded in 1998 • Open consortium of telecommunications companies (mix of large operators, large vendors, niche suppliers, test tool suppliers et al) • See www.msforum.org
What Does the MSF do? • Focuses on developing meaningful physical implementations of standards • Organises large-scale interoperability events to test and validate standards in implementations of interest to major carriers • Provides significant resource for members to leverage for achieving multi-vendor solutions • Provides key implementation feedback to vendors, carriers and SDO’s • See http://www.msforum.org/interoperability/GMI.shtml for details of all MSF IOT events
SDO community MSF NGN Architectural Framework Physical Scenarios Vendors Protocol Selection Implementations Standards MSF IA’s Test Plans Carriers Testing & Interoperability Programmes Validated, commercially viable tested standards Feedback How Does the MSF work?
What are the Benefits of Open Interoperability Testing? • Operators and Equipment Vendors that participate in Open Interoperability Events learn how multivendor next-generation products and networks will interoperate in the real world. • That information translates into several financial benefits: • Reduced time to market for deployment of interoperable solutions • Decreased costs and resources to resolve interoperability issues • Improved protocol documentation through facilitating clarifications in the tested standards via feedback to the appropriate SDOs • Thoroughly evaluated architectural framework for cooperatively designing end-to-end networking solutions
MSF GMI IOT Events Historically: MSF held Global MSF Interoperability Events (GMI) Multi site, multi protocol, end-end GMI events reflected the needs/focus of the telecoms industry at the time GMI2002: focused on Gateways & Controllers (MGCP, H.248) GMI2004: focused on SIP Servers GMI 2006: focused on IMS GMI 2008: added multiple access types into the IMS core (3GPP, 3GPP2, WiMAX, Broadband, TD-SCDMA, POTS) plus IPTV
MSF Post GMI IOT Events • Post GMI 2008, MSF changed strategy to running more focused events on an “as needed” basis • Restructuring of MSF Working Group structure • Parallel work streams (ad-hoc Working Groups) • Hosted LTE IOT Event in March 2010 • Hosted Performance IOT Event in November 2010

MSF Events: LTE IOT LTE IOT event in March 2010 Hosted by Vodafone and China Mobile, Testing Scenarios included Basic EPC Interoperability Roaming Non-LTE access to the EPC, Handover, Robustness Testing (“fuzzing”) Results liaised to 3GPP, NGMN, LSTI & GSMA White Paper available at http://www.msforum.org/interoperability/LTE.shtml
MSF Events: P-IOT 2010 • Performance IOT 2010 (P-IOT 2010) Event in November 2010 • Focussed on the management reporting interfaces of Session Border Gateways (access & N/W side) • Voice/Video/Data sessions under varying loads, • Validated reported information against i3F defined KPIs • Tested QoS reporting and problem isolation/location, • Results liaised to i3Forum & ATIS PTSC • White Paper available at http://www.msforum.org/interoperability/MSF%20P-IOT%20White%20Paper_2_2011_FINAL.pdf
Current Activities - Headline Items VoLTE (Voice over LTE) Network Robustness Content Distribution Networks (CDNs) Network-to-Network Interface (NNI) Performance Testing
VoLTE (1/2) VoLTE IOT Event planned for September 2011 Builds on the LTE/EPC executed in March 2010 Executes tests not performed during the previous IOT event Validates GSMA Permanent Reference Documents IR.88, IR.92, IR.65 Joint event with GSMA – co-operation agreement signed VoLTE IOT officially announced at GSMA Mobile World Congress in February 2011
VoLTE (2/2) Scope of VoLTE IOT event completed. Five defined scenarios : VoLTE (compliant to GSMA PRD IR.92), Roaming & Interconnect, (compliant to GSMA PRD's IR.65 and IR.88), 2G/3G access to EPC via both legacy/S4-SGSN, Handovers (intra LTE & LTE <-> 2G/3G), SON (Self-Optimising Networks).

Network Robustness (1/3) Multi-part Work Item covering : N/W Monitoring, Congestion & Overload Control, Disruption Testing, Network feedback & instabilities, Prioritization, End-End QoS, inc. NNI QoS in particular
Network Robustness (2/3) First IOT event, “P-IOT 2010” completed, November 8th-19th 2010 at NCS's XTC labs in Chantilly, Virginia P-IOT 2010 was the 1st of a series of planned IOT events and White Paper published February 2011 and liaised to i3Forum & GSMA. P-IOT 2010 focussed on the reporting / logging capability of SBGs (both access & n/w side) and includes: Voice sessions via an IMS core under varying load conditions Video sessions via an IMS core under varying load condition Data sessions under varying load conditions
Network Robustness (3/3) Next phase of work currently being scoped out Feedback received from i3Forum in response to MSF liaison following P-IOT 2010 event Potential future topics: Testing PCRF under congestion, LTE & Metro Ethernet Congestion, Additional Operational Measurement & CRD analysis, Further NNI testing, IP6 testing on SBGs & IP4/IP6 inter-working.
Content Delivery Networks Formal Work Item (WI) adopted in April 2010 Conduct Architectural Analysis and develop architectural framework for CDNs taking input from all SDOs LS received from ITU-T SG13 regarding CDN Functional Architecture Framework Define Physical Scenarios and Test Cases for an IOT event IOT Event planned for Q2 2012
NNI Performance Testing New WI agreed in Q1 2011 Study of IP NNI work in other fora Creation of a NNI Profile Considers both national & international IP NNI LSs sent to ATIS PTSC NG-CI, ETSI TC-INT, i3F, GSMA Define Physical Scenarios and test plans for future IOT events Initial scope of work looking at North American IP NNI NNI based on ATIS specs - IOT event planned for Q4/11. Close co-operation with ATIS PTSC NG-CI Subsequent work to look at international IP NNI
Ongoing activities with other fora VoLTE IOT jointly organised with GSMA and formally announced at GSMA MWC Regular contact with i3Forum regarding QoS & NNI issues Initial scope of NNI Performance Testing to be based on ATIS PTSC specs MSF attended IMS World Forum in March 2011 along with GSMA, ETSI, IMTC & IMSF to discuss current testing activities and future co-operation.
