INTERNET

• ONCE COMMERCIALIZED, INTERNET CAPACITY RAPIDLY
  USED UP
• RESEARCH REQUIREMENTS NEEDED HIGH CAPACITY LINKS

3
INTERNET2 BEGINNING

• 1996
• 34 RESEARCH INSTITUTIONS GET TOGETHER
• PRIVATE FUNDING FROM COS
• FED GOVT NEXT GENERATION INTERNET INTIATIVE
• NASA
• DOD
• GOVT FUNDING
• COMPLEMENTARY NETWORKS

4
MEMBERSHIP

• 0.5MM TO 1MM / YEAR / UNIVERSITY
• GOAL CONNECT UNIVERSITIES, SCHOOLS, LIBRARIES
• 3MM USERS

5
NETWORK

• 2 OPTICAL BACKBONES
• MCI VERY HIGH-PERFORMANCE BANDWIDTH NETWORK
  SERVICES (vBNS)
• ABILENE 10,000 MILE BACKBONE SPECIALLY BUILT
• CONNECTIONS
• DIRECT TO BACKBONE (25)
• GIGA-POPS (ACCESS POINTS)
• MIN CONNECTION 155 MEGABITS

6
WHY AND HOW

• WHY
• QUALITY OF SERVICE GUARANTEES
• PRIORITIZING DATA TRANSMISSION
• MULTICASTING
• HOW
• FEWER HOPS BETWEEN ROUTERS
• IPv6 TO INCREASE NUMBER OF INTERNET ADDRESSES

7
QUALITY OF SERVICE

• DATA LOSS
• LATENCY
• COLOR FIDELITY
• NOT ALL APPLICATIONS NEED IT
• MUST BE COST JUSTIFIABLE

8
MULTICASTING

• SAME MESSAGE? MANY DESTINATIONS
• MANY COPIES OF MESSAGE CREATED AT POINT OF
  ORIGIN EACH ONE TRAVELS THE COMPLETE DISTANCE
• ONE COPY.. DUPLICATION AT LATER POINT ALONG THE
  PATH.
• CURRENTLY IN USE BUT AUDIO AND VIDEO
  MULTICASTING POSE PROBLEMS

9
IPv6

• CHEAPER AND EASIER TO ADMINISTER(?)
• WINDOWS XP HAS SUPPORT FOR IPv6 BUILT IN
• NEED EXPANDED ADDRESSES FOR WIRELESS APPLICATIONS
• IPv6 USE WITH IPv4 PROBLEMS

10
APPLICATIONS

• ASTRONOMY OBSERVATIONS
• nanoMANIPULATOR
• CYBER-COLLABORATION
• TELEMEDICINE
• TELE-IMMERSION

11
APPLICATIONS IN ASTRONOMY

• GEMINI OBSERVATORY HAWAII
• HOW TO LET PEOPLE SHARE DATA
• RESEARCHER PERSPECTIVE
• HOW TO BE IN TWO PLACES AT THE SAME TIME

12
ADVANTAGES

• RESEARCHER ALERTED WHEN CONDITIONS ARE RIGHT
• REFRESH RATE 100 TIMES/SEC
• ROLE FOR AMATEUR ASTRONOMERS

13
nanoMANIPULATOR

• nanoTECHNOLOGY
• PHANTOMS FORCE-FEEDBACK MECHANISM TOUCH,
  SQUISH, EVEN SPLIT SUCH FIBERS IN TWO.
• COLLABORATION
• WANT EVERYONE TO HAVE THE SAME FEELING/PERCEPTIO
  N
• 1/20TH OF A SECOND
• TOUCH

14
TELEMEDICINE

• VIDEOCONFERENCING
• DATA LOSS
• LATENCY
• COLOR FIDELITY
• NOT ENOUGH FOR TELEMEDICINE
• NEED 768 KBIT/SEC CONNECTINO AT EACH END (FOR
  CURRENT APPLICATIONS)
• SECOND OPINIONS

15
TELE-IMMERSION

• TELECONFERENCING (VIDEOCONFERENCING)
  2-DIMENSIONAL VIEWS
• TELE-IMMERSION
• THREE DIMENSIONAL VIEWS

16
WHAT IT TAKES

• 7 DIGITAL VIDEO CAMERAS
• POLARIZED GLASSES / HEADSET
• INFRARED SENSORS SENSE MOVEMENT OF HEAD
• TWO SHARP PROJECTORS
• EIGHT HIGH-END PCs.
• (2MM SGI vs. 20,000 PCs)

17
WHAT IT GIVES

• 3-D PICTURES
• SEE AROUND PEOPLE
• APPLICATIONS
• BUILDING INSPECTIONS
• ??

18
WORKING GROUPS

• IPv6
• MEASUREMENT
• MULTICAST
• QUALITY OF SERVICE
• ROUTING
• SECURITY
• TOPOLOGY
