  1. 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/ EC Consultation Workshop on Networked Media Research, 19/01/10

  2. 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 EC Consultation Workshop on Networked Media Research, 19/01/10

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

  4. 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 EC Consultation Workshop on Networked Media Research, 19/01/10

  5. 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 EC Consultation Workshop on Networked Media Research, 19/01/10

  6. 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.) EC Consultation Workshop on Networked Media Research, 19/01/10

  7. Miscellaneous Issues and Requirements • Securitycontrol 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 EC Consultation Workshop on Networked Media Research, 19/01/10
