AIMS'99 Workshop Heidelberg, 11-12 May 1999

  1. 1. Project Overview Real-Time Services on the Internet EURESCOM P913-GI “Socrates” 14 Jan. - 31 Dec. 1999, BT, DT, FT, PT Hans-Detlef Schulz, DT AIMS’99 Workshop Slide 1 Heidelberg, 11-12 May 1999
  2. 2. Project Overview Purpose of SOCRATES • Investigate the Limitations of Real-Time over the Internet • Give Recommendations on Configurations that are suitable for Real-Time over Best- Effort Internet • Give Recommendations on where the Introduction of Bandwidth Provision is necessary • Measurements to identify the most suitable Technologies AIMS’99 Workshop Slide 2 Heidelberg, 11-12 May 1999
  3. 3. Real-Time Applications Streaming Applications • Audio/Video Streaming • Interactivity for VCR Functionality only • Server/Client Architecture • Audio/Video on Demand or Broadcast AIMS’99 Workshop Slide 3 Heidelberg, 11-12 May 1999
  4. 4. Real-Time Applications Conversational Applications • Video-Telephony • Conferencing • High Interactivity • Multiple Streams with different Priorities • Point-to-Point or Multi-Point Architecture AIMS’99 Workshop Slide 4 Heidelberg, 11-12 May 1999
  5. 5. Real-Time Applications Applications not considered • Internet Shopping • Internet Games • Internet Fax • Point-to-Point IP-Telephony without Video Content AIMS’99 Workshop Slide 5 Heidelberg, 11-12 May 1999
  6. 6. Approach Aspects for Consideration of SOCRATES • Packet Loss • Packet Delay • Delay Jitter • Varying Throughput • End-to-End Bandwidth • Subjective Reception AIMS’99 Workshop Slide 6 Heidelberg, 11-12 May 1999
  7. 7. Approach Targets (1) • Classification of – Applications and Products – Scenarios – Intended Use AIMS’99 Workshop Slide 7 Heidelberg, 11-12 May 1999
  8. 8. Approach Targets (2) • Based on the Classifications Recommendations are given - for which Types of Products, Scenarios, and Usage the Best- Effort Internet is sufficient - how much Bandwidth Control needs to be introduced based on the kind of Technology that is used AIMS’99 Workshop Slide 8 Heidelberg, 11-12 May 1999
  9. 9. Approach Approach • From Best Effort .. – Existing Internet – Reception Control at Receiver – Feedback to Sender – Bandwidth Adaptation • .. to Bandwidth Control – Intranet and Connection to ISP – Mapping between IP and Network – Different Protocols AIMS’99 Workshop Slide 9 Heidelberg, 11-12 May 1999
  10. 10. Approach Deliverable 1: Road-Map • Internet Technology • Real-Time Requirements • Standards • Market Trends • Commercial Products • Strategies for the Trials AIMS’99 Workshop Slide 10 Heidelberg, 11-12 May 1999
  11. 11. Approach Deliverable 2: Recommendations and Solutions • Measurement Technology • Classification of Products, Scenarios, and Usage - Either where Best-Effort Internet is sufficient - or where Introduction of Bandwidth Control is required AIMS’99 Workshop Slide 11 Heidelberg, 11-12 May 1999
  12. 12. Road-Map Deliverable 1: Road-Map AIMS’99 Workshop Slide 12 Heidelberg, 11-12 May 1999
