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

3. 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

4. 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

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

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

7. 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

8. 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

9. 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

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

11. 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

12. Typical Content Farm Implementation
5/13/2019

13. 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

14. 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

15. 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

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

17. The Next Steps Collaboration on an international scale
Raise profile of services
Secure unified copyright agreements
