1 Internet2/Abilene Perspective Guy Almes and Ted Hanss Internet2 Project NASA Ames -- August 10, 1999

2 Applications and engineering Applications Engineering MotivateEnables

3 What makes this hard?  Combination of: high bandwidth wide area intrinsically bursty applications  Need for multicast  Need for quality of service  Need for measurements

4 Applications Challenges  Raising awareness among all faculty  Providing “services-rich” network environment  Supporting application developers  Supporting deployment communities From packaging to ensuring end-to-end network environment is there

5 Approaches  Internet2 is a membership participation organization  Nothing is done in isolation

6 Examples  I2-Distributed Storage Infrastructure  I2-Digital Video

7 Outline of Engineering Issues  QoS Low-latency very-low packet loss  Multicast PIM-SparseMode, MBGP, MSDP  Measurements Surveyor: One-way delay and loss Traffic utilization End to end flows with gigaPoP help OC3MON -- passive measurements

8 Measurements Perspectives  Traffic Utilization: Easy, boring, but important to do well Periods, formats, etc.  Active Measurements: very accurate one-way delay and loss throughput  Passive Measurements: OCXmon etc Each monitor useful to all

9 Focusing In  Remember those meritorious applications?  Rôle of campus, gigaPoP, and backbone engineers in supporting aggressive applications

10 The bottom line  Supporting inter-university networking  Supporting advanced applications users know apps, but not infrastructure expectations  Supporting univ / gigapop / backbone / ngix infrastructure multiple support organizations multiple kinds of engineering commitment to cooperative end-end solutions

13 Abilene and Internet2  Internet2 as infrastructure: 150+ campus LANs about 35 gigaPoPs a few interconnect backbones  Abilene is the 2nd Backbone OC-48 trunks from Qwest Cisco 12008 routers with IP/Sonet OC-3 and OC-12 access to gigaPoPs

14 Seattle Kansas City Denver Cleveland New York Atlanta Houston Indianapolis Abilene -- Sep-98 Sacramento Los Angeles

15 Seattle Kansas City Denver Cleveland New York Atlanta Houston Indianapolis Abilene -- 29-Jan-99 Sacramento Los Angeles

16 Seattle Kansas City Denver Cleveland New York Atlanta Houston Indianapolis Abilene -- 10-Aug-99 Sacramento Los Angeles

17 Seattle Kansas City Denver Cleveland New York Atlanta Houston Indianapolis Abilene -- plus on order Sacramento Los Angeles

18 Seattle Kansas City Denver Cleveland New York Atlanta Houston Indianapolis Abilene -- plus on order plus expected Sacramento Los Angeles

19 Summary of New Connections  OC12: 7 now plus 4 ordered plus 3  OC3: 11 now plus 13 ordered plus 1  Most are IP/Sonet  Project ratio of 1::7 in traffic  Plus impact of routing

20 Multicast  Now running PIM-SM, MBGP, MSDP  Beginning multicast beta service  NASA demonstration: CalREN2, NREN, Abilene, NGIX-Ames 50 Mb/s to 80 Mb/s multicast flows Medical application  Emphasis of NOC and NCNE

21 Interconnect Issues  NGIX effort with the NGI/Internet2 JET Chicago: OC3 going to OC12 Ames: OC12 Washington: OC12 as soon as possible  International: StarTap plus Emphasize StarTap as the universal solution Optimize where appropriate Canada as an important special case
