improvements in how we conduct
research and engage in teaching and
learning
• Common attributes:
• Remote instrumentation and
interactive collaboration
• Distributed data storage and
data mining
• Large-scale, multi-site
computation

APPLICATIONS: HDTV
Raw HDTV Stream
• Packetized raw HDTV (1.5 Gbps)
• SC2001 public demo
• DARPA PIs Meeting: SEA->DC
area 1/6/02
• Application level measurement
• 3 billion packets transmitted
• 0 packets lost, 15 resequencing
episodes
• e2e network performance
• Loss: <8x10 -10 (90% confidence
level)
• Reordering: 5x10 –9
• Transcontinental 1-Gbps TCP (std 1.5
kB MTU) requires loss at the level of
3x10 –8 or lower
Slide 5

ABILENE
Networking Activity
• Internet2 networking is a fundamentally
hierarchical and collaborative activity
• International networking
• Ad hoc -> Global Terabit Research Network
(GTRN)
• National backbones
• Regional networks
• GigaPoPs
• Campus networks
• Much activity now at the metropolitan and
regional scales
Slide 14

ABILENE
Future of Abilene
• Qwest has extended
commitment for another 5
years – to October 2006
• Upgrade of Abilene backbone
to optical transport capability
• 4 times increase in core
bandwidth, to 10
gigabits/second (OC 192)
• New wavelength
capabilities (MWDM)
Slide 15

ABILENE
Next Generation Abilene
• Native IPv6
• Motivations
• Resolving IPv4 address
exhaustion issues
• International collaboration
• Run natively - concurrent with
IPv4
• Replicate multicast deployment
strategy
• Close collaboration with
Internet2 IPv6 Working Group
on regional and campus v6
rollout
Slide 16
• Network resiliency
• Increasing use of
videoconferencing & VoIP
impose tighter restoration
requirements (<100 ms)
• Abilene ’s will not be protected
like SONET
• Addition of new measurement
capabilities
• Active & passive probing
• Surveyor, Abilene
“Observatories,”
Performance beacons
• Latency & jitter, loss, TCP
throughput

CONCLUSION
Where to go from here…
• Working Group or BOF meeting
• Identify tasks, activities and goals
pertinent to the community
• Select an already established meeting
at which to hold a BOF meeting
• Determine individuals who are willing to
lead a working group
• Identify a schedule against which activities
can be measure (don’t let the inertia stop)
