Astronomy & Internet2
• What does Internet2 have to offer for the astronomy community?
• Access to advanced, high-performance network
• Find parallels with work being done by other communities
• Connections to researchers & peers around the world (BOF/Working Group)
• Loaner hardware, expert advice, etc.
INTRODUCTION & OVERVIEW
April 2002Internet 2 Applications Update Slide 4
Attributes of Advanced Apps• Provide qualitative and quantitative
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 • Real-time access to remote
resources• Dynamic data visualization• Shared virtual reality
APPLICATIONS
April 2002Internet 2 Applications Update Slide 5
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
APPLICATIONS: HDTV
April 2002Internet 2 Applications Update Slide 6
HENP and NEESgrid• High Energy and Nuclear Physics
• Transferring petabytes of data a year, gigabytes per second per experiment
• Cascading data storage model, near-zero packet loss per data stream, distributed database for end-user data manipulation
• VRVS collaboration system supports multiple video formats and technologies
• Network for Earthquake Engineering Simulation
• Running hybrid experiments synchronizing physical and computational experiments
• Synchronizing large volumes of data of different types: sensor, video, etc.
APPLICATIONS: GRIDs
April 2002Internet 2 Applications Update Slide 7
Internet2 Mission• Develop and deploy advanced
network applications and technologies for research and higher education, accelerating the creation of tomorrow’s internet.
• Supporting advanced service efforts such as:
• Multicast
• IPv6
• QoS
• Measurement
• Security

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
ABILENE
April 2002Internet 2 Applications Update Slide 15
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)
ABILENE
April 2002Internet 2 Applications Update Slide 16
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
• 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

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)
