What is the MSF? • The Multi. Service Forum (MSF) is a global association of service providers and system suppliers committed to developing and promoting open-architecture, multiservice switching systems. • Founded in 1998, the MSF is an open-membership organization. • The MSF’s activities include developing implementation agreements, promoting worldwide compatibility and interoperability, and encouraging input to appropriate national and international standards bodies. • For more information about the MSF and its members, visit the MSF web site at www. msforum. org.

Where the MSF Fits • MSF is not a Standards Development Organization (SDO) • Focus on developing meaningful physical implementations of standards • Use of large-scale interoperability events to test and validate standards 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 Copyright 2007: Multi. Service Forum

MSF Industry fit SDO community MSF NGN Architectural Framework Physical Scenarios Protocol Selection Implementations Vendors Standards MSF IA’s Test Plans Carriers Testing & Interoperability Programmes Validated, commercially viable Implementation Agreements (IAs) Feedback Copyright 2007: Multi. Service Forum

MSF Focus MSF NGN Architectural Framework Physical Scenarios Interop testing is only meaningful in the context of a specific network configuration Options must be specified, and ambiguities clarified Protocol Selection MSF IA’s Test Plans Testing & Interoperability Programmes Validated, commercially viable Implementation Agreements (IAs) Detailed test plans required to ensure complete coverage and consistency Interop program requires start-to-finish program management and coordination Interop programs are best at validating the standards (not products) Copyright 2007: Multi. Service Forum

MSF Delivery Process • Focus on accelerating the deployment of new technologies emerging from standards by supporting interoperability and test events as required by MSF members • Rapid development model – Mapping of SDO architectures to real world implementations – Develop physical scenarios – Develop detailed test cases – Profile protocols where necessary to facilitate the testing • Provide key implementation feedback to vendors, carriers and standards organisations Copyright 2007: Multi. Service Forum

EPC / LTE Interop Event • MSF EPC/LTE Interoperability Event was hosted March 15 – 20, 2010 by the Vodafone Test and Innovation Centre, Dusseldorf, Germany and China Mobile facilities in Beijing • Designed to test standards compliance of vendors implementation of Evolved Packet Core (EPC) network scenarios to 3 GPP Release 8 standards • Gauge vendor support for this technology • Mix and match of different vendor EPC network elements to test interoperability • Performed inter-site and intra-site testing • 8 Vendors participated in the event Copyright 2007: Multi.

Event Planning • • • • • Project Plan Hire full-time Event Coordinator Determine host sites i. e. , carrier labs Project Requirements Document (PRD) Event announcement to industry – press release Non-Disclosure Agreement (NDA) Participant recruitment package Letter of Invitation Letter of Intent Participant contract (Event Agreement) Event execution documents, etc. Tool requirements (scheduling, test data recording, reports) Network and addressing plans Requests for information from participants Master test schedule Pre-event briefing presentations Implementation Agreements (IAs) Test Plans Other documents as needed Copyright 2007: Multi. Service Forum

Event Testing • Determine interfaces and functions to be tested • Create physical architecture document • Test plans written from 3 GPP R 8 specifications by MSF member companies • Protocol profiles written where required • Labs and vendor equipment configured (1 week set-up, 2 weeks testing, 1 week removal) • Test results loaded into test tool by event monitors – only test partners see results • Patching/retesting if time permits Copyright 2007: Multi. Service Forum

Event Wrap-up • Create Press Release • Analysis test data • Write White Paper – test setup, results (all results are non-attributable) • Liaison appropriate SDOs regarding problems found • Lessons learned – all participants discuss what went well and what could be done better • Determine what event testing is to be carried forward as well as candidates for future testing Copyright 2007: Multi. Service Forum

MSF LTE/EPC by the Numbers • 2 Number of test labs • 18 Months from planning to white paper • 50 Engineers on site (both labs) • 40 Company support engineers on call (both labs) • 300 Test plan pages • 95 Test cases • 550 Scheduled tests – different vendor configurations • 12 days of testing • 11 hours/day of testing Copyright 2007: Multi. Service Forum

EPC / LTE Interop Event White Paper • A free download of the event white paper “MSF LTE Interoperability Event – Multivendor testing in global Evolved Packet Core Networks” is currently available: http: //www. msforum. org/interoperability/LTE. shtml • The MSF work plan for 2010/2011 consist of 1) LTE/EPS Phase 2 that builds on the recent LTE event success, 2) MSF/ATIS IIF IPTV IOT, 3) Content Distribution Networks (CDN) that builds on and broadens the IPTV work, 4) Performance Testing and 5) Robustness testing across all of the above mentioned areas.
