MEF Q4 - Applications Committee What is the IMTC? International Multimedia Telecommunications Consortium Mission: Promote and facilitate the development and use of interoperable, real-time, multimedia telecommunications products and services based on open international standards. MEF Q4 - Applications Committee

MEF Q4 - Applications Committee Problem Statement Standards interpreted differently Solutions are competitive Interoperability is hard MEF Q4 - Applications Committee

SIP Interconnect AG - Charter Forum for IMTC member companies to cooperate and pool resources on issues and extensions to SIP based enterprise communication applications Best practices documents as shared foundation to interoperate Identify and tackle challenges and opportunities with interoperability, operation, and integration of SIP based applications with emerging communication and networking technologies MEF Q4 - Applications Committee

SIP Interconnect AG – What We Do Organize interoperability test events Done in cooperation and coordination with WebRTC, MANE, SSV, and UC SDN activity groups and with SIPit Provide forum for members to agree on SIP profile for communication applications Particularly for interconnecting with other application and network technologies (e.g. WebRTC, SDN, IPv6) Educate members on recent developments in SIP standards and market evolution MEF Q4 - Applications Committee

Best Practice Documents SIP Video Profile Add video (H.264) to SIP based audio telephony Role Based Video Add content sharing to SIP based video conferencing SIP Security Enable adoption of secure signaling (TLS) and media (SRTP) MEF Q4 - Applications Committee

MEF Q4 - Applications Committee SIP Video Profile Asymmetric negotiation Bandwidth, Video Coding Complexity Bandwidth Indications - Session level vs. media level RTP/AVPF profile – SDP offer/answer negotiation Flow control - SDP vs. RTCP feedback (TMMBR) Intra frame request - SIP INFO vs. RTCP feedback (PLI/FIR) H.264 – Recommended set of parameters MEF Q4 - Applications Committee

MEF Q4 - Applications Committee Recent Developments SIP Video Profile IMTC1015 – Published (obsoletes IMTC1013) Improves interworking with IMS/3GPP Addresses interworking issue with RTCP feedback parameters Test Cases Added to address issue with “m-stream” vs. “mstrm” IETF draft Negotiating SRTP and RTCP Feedback using the RTP/AVP Profile, draft-ietf-mmusic-opportunistic-negotiation MEF Q4 - Applications Committee

Role Based Video Streams Video - “main” vs. “presentation” RFC 4796 “content” attribute Mapping: “slides” for H.239 “presentation” “alt” for H.239 “live” “main” for the main video stream BFCP (Binary Floor Control Protocol) UDP instead of TCP for transport MEF Q4 - Applications Committee

Recent Developments IETF BFCPBIS Working Group (Charter) Role Based Video Streams IETF BFCPBIS Working Group (Charter) draft-ietf-bfcpbis-rfc4582bis in RFC editor’s queue draft-ietf-bfcpbis-rfc4583bis in working group last call IMTC best practice to be updated per new RFCs IMTC Last Call Publish as IMTC10xx MEF Q4 - Applications Committee

MEF Q4 - Applications Committee SuperOp! Annual event focused on interoperability Developers, testers, architects test interworking of bleeding edge and production products and solutions MEF Q4 - Applications Committee

MEF Q4 - Applications Committee SuperOp! 2018 Host as part of MEF Q2 Meeting? Combine with Euro18 LSO Hackathon? MEF LSO Hackathons encourage software developers and network experts to collaborate and develop utilities, ideas, sample code and solutions that show practical implementations of MEF- defined services and LSO APIs MEF Q4 - Applications Committee
