UKERNA and Streaming Media Chris Oakley SuperJANET4 Applications Officer 5/13/2019

Introduction Requirements for Real-Time Content Provision within JANET community Applications Areas Current Research within UKERNA Models for deployment under SuperJANET4 5/13/2019

The Requirement: Driving Factors Previous pilots – Imagination/Universities Networked Moving Image Pilot, Streamer 2000 Direct approaches to UKERNA from community Need for a centralised service with traffic management Commercial development of content and application services 5/13/2019

The Problems Wide variation in campus connectivity SuperJANET4 will provide 2.4Gbit/s in the backbone-still limited for media rich content Conflicting ideas about the application of streaming media 5/13/2019

Real-Time Media Applications Video on Demand Account Based Revenue Protected Multicast Applications Live Multicast Infrastructure Scheduled Programming Content Creation Applications 5/13/2019

Current Research Demonstrator Project, due mid June 2000 Testbed for technology Application refinement 5/13/2019

Demonstrator Technology Based around SGI MediaBase/Origin 200 Server Support for MPEG 1&2, QuickTime, RealMedia Flexible solution Scalable streaming Standalone system Streams encoded remotely on Media100 iFinish system and remotely mounted Initial test to be carried out over 100Mbit LAN Monitoring 5/13/2019

Cross-Evaluation SGI system to be cross-evaluated against Cisco’s IP/TV server set Control server-cluster management Broadcast server-multicast scheduled and live event Archive Server-unicast VOD system Supported formats: MPEG1&2 MPEG 4 Windows Media 5/13/2019

Demonstrator Testing Testing over JANET to commence Mid July Exchange of files with MediaBase at Manchester Computer Centre Also mirroring of datasets between sites Controlled client group 5/13/2019

Demonstrator Applications Video on Demand Revenue models Account based Scheduled Multicast Live Multicasting tests 5/13/2019

SuperJANET4-Application Deployment Content Farms to be implemented at key nodes within the network Mirroring across sites as well as caching to be employed in order to minimise network impact of this traffic Service to undergo progressive rollout from launch of SJ4 5/13/2019

Typical Content Farm Implementation 5/13/2019

Management Strategies Quality of Service will seriously affect these services SJ4 QoS services will be used to complement broadband applications Video assets are to be encoded at bitrates appropriate to usage 5/13/2019

Dual Levels of Service Narrowband service Will utilise proprietary media formats (QT,Real etc.) Will cater for those areas with limited connectivity Also ideal for less critical applications Broadband Service Will utilise MPEG 2 A premium service (ultimately charged as such!) Catering for quality critical applications e.g. Medical Education 5/13/2019

Users and Content Content to be primarily sourced inside of the JANET community Agreements for access of content outside of JANET Users identified primarily as Educators and students utilising LT Content creators 5/13/2019

Futures Develop further multimedia integration Look for solution to problem of metadata Possibility of centralised UK media content archive 5/13/2019

The Next Steps Collaboration on an international scale Raise profile of services Secure unified copyright agreements 5/13/2019
