April 2002Internet 2 Applications UpdateSlide 2

Presentation Outline• Applications 5 min

• Examples of current projects

• About Internet2 5 min• Organization, Membership

• Internet2 & Abilene 10 min• Backbone, Characteristics, Connections

• Q and A 5 mintotal time ~25 min

INTRODUCTION & OVERVIEW


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


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


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 1.5kB MTU) requires loss at the level of 3x10 –8 or lower

APPLICATIONS: HDTV


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


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

Internal Organization• Advanced Network Infrastructure• Applications• Engineering• Middleware• Partnerships

• Internet2 is primarily an organization driven by our membership

ORGANIZATION


Internet2 Members189 universities (yellow dots)70 corporations40 non-profits and gov’t labs

ORGANIZATION: Membership


Internet2 Network Backbone• Abilene

• The name of Internet2’s network infrastructure

• Apr 1998: Project announced at White House

• Jan 1999: Production status for network• 12 GigaPOPs around the conuntry• NOC located at Indiana University

ABILENE

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

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)

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

• Network resiliency• Increasing use of

videoconferencing & VoIPimpose tighter restoration requirements (<100 ms)

• Abilene λ’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

ABILENE


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)
