  1. MultimEDia transport for mobIlEVideo AppLications 9 th Concertation Meeting Brussels, 13th February 2012 MEDIEVAL Consortium

  2. Outline • The MEDIEVAL project • Planned demos and services • Dissemination summary 9th Concertation Meeting

  3. MEDIEVAL Objectives • Video is a major challenge for the future Internet • Current mobile Internet IS NOT designed for video • Specific enhancements for videoshould be introduced at all layers of the protocol stack where needed • MEDIEVAL : Evolutionary path for a truly video-for-all philosophy • Evolved cross-layer algorithms and mechanisms • Quality of Experience based solutions for mobile video delivery • Flat mobility architecture based on a distributed DMM concept • MT multi homed through an innovative Abstract Interface; mechanisms to optimize Video transmission over heterogeneous air interfaces • a mobile CDN (i.e. adding of new CDN entities in the mobile network) concept for efficient media delivery 9th Concertation Meeting

  4. MEDIEVAL network deployment 9th Concertation Meeting

  5. The MEDIEVAL project • MEDIEVAL is an operator-driven project specifying and demonstrating a mobile video architecture with cross-layer mechanisms to provide high quality of experience to users 9th Concertation Meeting

  6. MEDIEVAL Architecture • Medieval architecture is divided into 4 subsystems • Video Service Control (WP2) • Links the applications and services to the underlying network delivery entities • Transport Optimization (WP5) • Provides optimized video traffic in the mobile operator's core network • Mobility Management (WP4) • Evolves today's mobile Internet architecture to more efficiently support growth of video services, based on flow mobility and DMM • Wireless Access (WP3) • Provides enhanced video delivery in the last (wireless) hop, mainly focusing on novel access techniques and technology abstraction • Strong level of cross-layer interactions between the subsystems 9th Concertation Meeting

  8. Planned demo 1 : VOD Scenario VOD server Step 1: MN2 connects to MAR1 and gets video2 (from cache1 or VOD Server) Step 2: MN2 gets another flow (e.g.: VoIP) Step 3: MN2 discovers a WiFi coverage (MAR2) Step 4: MN2 moves out of WLAN coverage, and goes under MAR3 and changes cache . The video-flow comes from cache3, VoIP is anchored to MAR1 cache3 cache2 cache1 3G Main features of this demonstrator are: DMM based intra-domain handover (both between homogeneous and heterogeneous PoAs), WiFi Offload support CDN solutions ftp Video 2 Video 2 9th Concertation Meeting

  9. Planned demo 2 : PBS Scenario Step1: LiveU SW sends in uplink the contents over multilink to the LiveU node. Step2: The LiveU node sends the content to the Unicast/Multicast translation node Step3: The Unicast to Multicast Translation sends the content in multicast Step 4: mobile terminals receive the content in multicast (multicast receivers) Step 5: mobile receivers will move (mobile-initiated multicast receiver mobility) 5 4 1 2 Main features of this demonstrator are: Multicast listener mobility Multilink transmission eMBMS 3 9th Concertation Meeting

  10. Planned demo 3: Inter-operator Video Service provided by domain operator A (VoD) Step1: VOD service activation by MN1 Step2: Congestion in the RAN is detected and Transport Optimization triggers layer dropping in the LTE cell; As congestion does not improve, traffic shaping is triggered in the Core network. Step3: MN moves to WIFI Operator B ; Tunnel is setup to allow session continuity (same IP address as before); MN keeps on downloading the same video but traffic optimization is not possible; Step4: WIFI gets congested and the QoE is not acceptable as compared to what was shown in step 2 Main features of this demonstrator are: Packet marking and dropping in LTE access Traffic shaping in the Core Network Inter-operator mobility Benefits from MEDIEVAL architecture on the QoE 9th Concertation Meeting

  11. Dissemination Summary • Publications • Y1 : top workshops and conferences (18); leading journals (9) • Y2 : top workshops and conferences (8 + 4 submitted); leading journals (8 + 7 submitted) • Standards • IEEE : Active in 802.21 (MIH), evaluation of 802.11aa (Video Streams Transport) • IETF : Active in NETEXT, MEXT, MULTIMOB, ALTO • 3GPP : Contributions to SA1 / SA2 • 3 patents applications filed 9th Concertation Meeting
