Multicasting Across Internet2 from the Edges of the Network

1. Multicasting Across Internet2 from the Edges of the Network Presenters: Dan Cotton, Bob Dixon, Kevin Gamble, Jim Sturm

2. ADEC Web Site www.adec.edu

4. Goal: Bring advanced networking applications to geographically remote learners for purposes of research, teaching and extension.

5. Objectives AISEP will: • explore use of satellite to deliver Internet services to determine compatibility of satellite technology with I2 services and applications

6. Objectives (cont.) • explore deployment and integration of DE applications, including collaborative applications at rural, remote institutions and extension learning centers

7. Research questions • establish standards for "acceptable, application-based Internet" for remote locations • understand how to establish, build and support a satellite-based IP network

8. Research questions (cont.) • build a satellite gateway to the commodity Internet and I2 • investigate QoS • study network performance

12. Unicast Vs. Multicast

13. Multicast Advantages • Increases network efficiency • Consolidates bandwidth • Reduces server load and cost • It scales

14. Multicast: End-to-End • Internet2 • PIM Sparse Mode versus DVMRP • Iowa State University • Multicast video streaming • ITEC-Ohio • ADEC router configuration • Monitoring • SDSC

15. Multicast: End-to-End • Lessons learned • Technology worked • Internet2 multicast support was intermittent • Can gateway between PIM Sparse Mode and DVMRP • Many I2 sites NOT multicast enabled • Cannot depend on it for regular use

16. Multicast: Head-end

17. Multicast: Head-end • Lessons learned - Video • Apply good production techniques • Balance input sources (i.e., video and audio levels) • Managing the convergence of TV and computer video production • Staff appropriately

18. Multicast: Head-end • Lessons learned - Network • Running Mrouted (i.e., daemon running on local CPE) • Coping with the LAN (i.e. NAT, firewall, filters, etc.) • Educating local sites

19. Multicast: Head-end • Lessons Learned – QuickTime • Turned unicast to multicast • MPEG4 = good quality audio/video • No discernable difference using 400k vs. 1.2M MPEG4 streams

20. Multicast: Head-end

21. Transportable System Design Goals • Provide high-speed Internet access for ALL purposes, including computers, telephones and PDAs. • Inexpensive to build and operate • Off-the-shelf parts for easy duplication

22. Transportable System Design Goals (cont.) • Easy to operate by one person with one day training, with NO hand tools. • Small and light • Reliable and adaptable to diverse field conditions • Easily modified

23. Planned Applications • Emergency communications. • Provide distance learning in under connected locations such as rural areas and inner cities. • Link field research to campus computers and laboratories and collaborators worldwide. • Link field instruction and demonstrations to campus classrooms.

24. Planned Applications (cont.) • Link field activities to remote databases, eg via PDAs. • Special events, conferences, fairs, etc. • Remote monitoring of construction projects.
