1 QoE-Aware Multimedia Content Delivery Over Next-Generation Networks M. Oğuz Sunay July 9, 2013 Second Romeo Workshop PAGE: 1 M. Oğuz Sunay, Özyeğin University Istanbul, July 9, 2013

2 Romeo High-quality stereoscopic 3D content is to be broadcast End point peers may also serve mobile devices Supplementary 3D multiview content to be distributed via a tree-based P2P All remote users to be synchronized for the delivery of 3D video. Both DVB and IP networks to serve all collaborating users at the same time PAGE: 2

3 Outline Demand for Multimedia Multimedia Content Delivery SC / CDN / P2P / Hybrid Economics of Multimedia Delivery Establishing a Price & Corresponding Service Profit Localization The ALTO Protocol Network Evolution & Multimedia Software-Defined Networking (SDN) Wireless Networks and QoE Interplay of Resource Allocation & QoE Conclusions PAGE: 3

4 Demand for Multimedia PAGE: 4

5 The Zettabyte Era Annual global IP traffic will reach the zettabyte threshold by the end of By 2017, it will be 1.4 zettabytes. Cisco, The Zettabyte Era - Trends and Analysis, White Paper, May 29, 2013 PAGE: 5

6 What is a Zettabyte? PAGE: 6

7 What is a Zettabyte? 1 zettabyte amounts to 36,000,000 years of HD video This is the equivalent of the entire Netflix catalog 3,177,000 times. PAGE: 7

8 Internet Today PAGE: 8

10 What Type of Video? PAGE: 10

11 How Will We Get Our Video? PAGE: 11

12 Multimedia Delivery over the Network PAGE: 12

13 Client-Server versus P2P PAGE: 13

14 Content-Delivery Networks PAGE: 14

15 CDN Issues How to select a server for a client? DNS redirection Application level redirection How to distribute content amongst servers? Popular content Rarely accessed content PAGE: 15

16 CDN Issues Factors for server selection: RTT Load Balancing Diurnal effects Variations across DNS servers Limited availability of rarely accessed content PAGE: 16

17 YouTube CDN Torres et.al. Dissecting Video Server Selection Strategies in the YouTube CDN, PAGE: 17

18 CDN + P2P PAGE: 18

19 Network Economics PAGE: 19

20 Economics of Networks Jean Walrand - in Performance Modeling & Engineering, Liu & Xia (eds.), Springer, 2008 PAGE: 20

21 Economics of Networking Finding the Most Profitable Delivery Framework for Streaming Video Profit = Revenue - Cost Cost Reduction Profit Maximization Revenue is dependent on clients willingness to pay for the service. This in turn establishes a price for the service. The lower the QoE the less the clients are willing to pay. Increasing QoE requires increasing the cost PAGE: 21

22 Economics of Networking Finding the Most Profitable Delivery Framework for Streaming Video Consider the following: Video broadcast/multicast service Cost of serving a client is linear in the number of clients In P2P, we allow %100 assistance ratio Two price models: Pay upfront, Pay when you start watching Fixed price: Same price for all clients PAGE: 22

23 Economics of Networking Finding the Most Profitable Delivery Framework for Streaming Video QoE Parameter: Pre-Roll Delay Macroeconomic theory states that the price of a service decreases with increasing delivery time delay from the present time. The impact of this decrease is compounded with delay time PAGE: 23

24 Economics of Networking Finding the Most Profitable Delivery Framework for Streaming Video CDN Profit P2P Stringent QoE requirements QoE Tolerance Non-Stringent QoE requirements Altan & Sunay, Profit Optimizing Transmission of Streaming Multimedia Broadcast in a Peer-to-Peer Network, July PAGE: 24

25 Localization PAGE: 25

26 Problems with CDN RTT is not necessarily a good metric for server selection DNS based / Application based redirection potentially causes delays PAGE: 26

27 Problems with P2P Peer selection in P2P networks are network inter-connection, congestion oblivious ISP economics are not considered ISPs can not control their own networks PAGE: 27

28 The ALTO Protocol IETF draft - version 16 - May 20, 2013 Penned by Google, Cisco & Yale University Describes an information sharing service between ISPs and applications PAGE: 28

29 BitTorrent Operation HTTP GET example.torrent example.torrent Web Server apptracker register list of random peers ID :6881 ID :5692 ID :4545 ID :6882 User (peer) Peer 40 Peer 2 Peer 1 PAGE: 29

46 Conclusions Internet traffic is exploding. Video has become the killer application. Video delivery architecture must not only be technically but also economically feasible. PAGE: 46

47 Conclusions For acceptable QoE the following are important: location of content serving peer/server link quality PAGE: 47

48 Conclusions Communication between the application and the network layers is important SDN also enables end-to-end route optimization For wireless links, QoE-aware resource allocation is crucial. PAGE: 48
