MEDIEVAL Objectives• Video is a major challenge for the future Internet• Current mobile Internet IS NOT designed for video

• Specific enhancements for video should 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

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

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

Planned demo 1 : VOD Scenario

cache1

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

Main features of this demonstrator are:

DMM based intra-domain handover (both between homogeneous and heterogeneous PoAs), WiFi Offload support CDN solutions

Planned demo 2 : PBS ScenarioStep1: 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 nodeStep3: 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)

Planned demo 3: Inter-operatorVideo Service provided by domain operator A (VoD)

Step1: VOD service activation by MN1Step2: 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 accessTraffic shaping in the Core NetworkInter-operator mobilityBenefits from MEDIEVAL architecture on the QoE
