1. EC Consultation Workshop on Networked Media Research, 19/01/10 Thoughts on Future Networking and Network Management for Ubiquitous Media Delivery Dr. Ning Wang Centre for Communication Systems Research University of Surrey Guildford United Kingdom http://www.ee.surrey.ac.uk/personal/n.wang/

2. EC Consultation Workshop on Networked Media Research, 19/01/10 Major Challenges Innovation of healthier business models for ubiquitous media/content delivery at Internet scale Future media/content provisioning and handling solutions - New networking paradigms for ubiquitous media/content delivery - Media-network management (MNM) integration Other issues and requirements

3. EC Consultation Workshop on Networked Media Research, 19/01/10 Overview New paradigms for media provisioning and handling Media-centric networking platforms Integrated media-network management (MNM) New business models for a media-centric Internet Requirements and issues (Security, QoS, energy-efficiency, …)

4. EC Consultation Workshop on Networked Media Research, 19/01/10 Business Model Innovation Current situation - Limited business opportunities for stakeholders (ISPs, content providers, service providers, end users…) - The Internet was originally designed based on the model of host-to-host communications rather than content/media access and delivery Making business models healthier - To allow diverse channels for creating revenues for a variety of stakeholders - In particular, to encourage end users to seek business opportunities in providing both media creation and delivery services Innovation from EU research projects will put Europe in a globally leading position

5. EC Consultation Workshop on Networked Media Research, 19/01/10 Media-centric Network Platforms Overlay based network platforms on top of the “dumb” Internet - Incremental schemes, e.g. existing CDN based solutions - To add dedicated application-layer content/media handling functions (as patches) where necessary Radical approaches for natively enabling ubiquitous media/content delivery with intrinsic functions - Disruptive paradigms with intrinsic functions for supporting large-scale media/content delivery - Native content resolution, naming/address, routing protocols to take the place of existing IP/DNS based schemes Network virtualisation for media/content delivery? - To enable smooth migration from overlay-based approaches to future revolutionary solutions - To deal with different types of media/content as well as heterogeneous QoS requirements

6. EC Consultation Workshop on Networked Media Research, 19/01/10 Integrated Media-Network Management Network resource management  media-network resource management - Current situation: decoupled content/media management and network management - In future media-centric network environments, media/content should be treated as one distinct dimension of resources, together with traditional network resources such as bandwidth Integration of network and media resource management - Preliminary step: content-aware network management and network- aware content management as complementary functions - Long term envisions: multi-dimensional resource management in future media networks - Adaptive/autonomic media-network management in dynamic environments (e.g. change of network conditions and content delivery requirements etc.)

7. EC Consultation Workshop on Networked Media Research, 19/01/10 Miscellaneous Issues and Requirements Security control in media creation and delivery - Media handling based on the current host-to-host communication model: content can be fetched only when its physical source is trusted - In future media-centric network environments: users only care about the content but not necessarily its actual source - Security control becomes more challenging Energy efficiency in handling rich networked media - Energy awareness has already been investigated in Internet-based communications and services - Energy reduction in future media/content centric networks can be also envisaged: much higher complexity/overhead in processing/delivering/storing rich media/content in the Internet - Possible solutions: (1) design of green media-centric networking protocols (2) energy-aware MNM paradigms
