MSDN – Media Story Delivery Network Delivering Personalised and Distributed Media

1. MSDN – Media Story Delivery NetworkDelivering Personalised and Distributed Media Stuart Porter Ben Tagger

2. Outline • What is the problem? • The movement of networked media. • Is this problem important? • What is our solution? The M-SDN! • Current practice. • An overview of the M-SDN. • Why this is difficult in the current Internet. • How Middleware helps us build applications like the M-SDN. • Delivery of media experiences. • What is the impact of this work? Stuart Porter and Ben Tagger

3. Media Usage in the Current Internet… YouTube Future - 2016 • 4 B hours of videos per month. • 1 T views in 2011. • 25% of these from Mobile devices. • 1.2m mins of video per sec. • 86% of global traffic. • Online Video Industry - $28b BBC • 190m requests per month. • +25% from last year (mobile +95%). $$$ • AOL Video Ad Revenue • $10m (2010) to $100m (2012) CISCO Stuart Porter and Ben Tagger

5. What’s the problem? • Content production companies are producing more media and more versions • Plethora of channels • New international markets • Different channels and markets have different requirements • Length & ad breaks • Tussles between content & local restrictions • Delivered Format • Subtitles, translations and aural description files Stuart Porter and Ben Tagger

6. Expensive • Extra days of work in the edit suite • Multiple viewing copies created in multiple formats • Duplication costs & international transportation • Low res (mobile) High res (HDTV) • Currently network cannot identify that large parts of different files are identical • Caching not possible to save resources and time • Hard to pull parts from separate repositories Stuart Porter and Ben Tagger

7. Is it important? • Yes • Broadcasters are losing money • Therefore they pay less for content • Content producers who still have high overheads • Producers need to find ways to cut costs without cutting quality, quantity or staff. • So a digital rights management solution where an overall storyline can be adapted based on the dynamically changing rights of a user would be beneficial.

10. Why is this Difficult in the Current Internet? • Fine-grained access to Networked Media • Access control, parental control and ethical constraints. • Serving personalised, democratised content. • Logistics of version storage leading to version management nightmare. • Current: Delivery of monolithic blobs of media. • M-SDN: Delivery of personalised, distributed and dynamic media experiences. Stuart Porter and Ben Tagger

11. Information-Centric Middleware Currently… • ICN places emphasis on information at the Network layer, • Blackadder uses a pub-sub architecture, • any applications must operate directly on this layer. We want… • the emphasis on information to continue at the application layer. • to provide natural abstractions that facilitate ICN use. • So, we need middleware. Stuart Porter and Ben Tagger

12. Features of the Middleware Our middleware… • extends native ICN metamodelling, adding expressivity, • enforces a consistent, satisfiable network metamodel, • leverages these features to enable (non-native) network mechanisms, such as • browsing, • querying/searching, • distributed querying.

18. What’s the Impact? • ICN allows increased competition • Embedding M-SDN in ICN architecture means user can request differentiated services • Enables network providers to optimize delivery according to implicit and explicit preferences of subscribers • Potentially leading to • Fairer pricing strategies • New market mechanisms for content delivery • Move away from flat pricing structures Stuart Porter and Ben Tagger

19. M-SDN can also allow changes to current models • Exponential growth of internet traffic – esp. video • Investment without direct positive effect on revenue • Content providers are increasing profits - at the expense of ISP’s investment in capacity Stuart Porter and Ben Tagger

20. New SLA’s possible which allow per item charges for uploads and downloads • Content creators pay ISPs’ to upload items • In turn they are paid by consumers who download items • “Visiblity” across the network achieved through M-SDN and ICN could enable money flow from user to provider • Users could also monitor SLA’s on per item basis Stuart Porter and Ben Tagger

21. BEWARE • Possible adverse effect on privacy • Providers could also monitor users on per item basis • Users may not take kindly to per item charges • Whilst they will agree that it is fairer, users like to know what they are paying each month, and who they are paying it to. Stuart Porter and Ben Tagger
