Internet2: Developments and Directions
CANARIEThird Annual Advanced Networks WorkshopDecember 15-16, 1998
Doug Van [email protected]
Internet2 Project Goals
Enable new generation of applications
Re-create leading edge R&E network
capability
Transfer capability to the global
production Internet
Outline
Review of progress Directions for 1999 Status Updates on:
• Abilene• QBone• Middleware
Internet2 in a global context
Progress
2+ years ago:Internet2 Project formedOctober 1996
1+ year ago: UCAID IncorporatedOctober 1997
8 months ago:Abilene LaunchedApril 1998
Today 135 universities 44 corporations 7 gigaPoPs connected to vBNS Abilene demonstrated/nearing
production Abilene peering with vBNS, CANARIE QoS -- QBone initiative launched Middleware initiative launched
Challenges
Maintain focus on advanced Internet• Production Internet rapidly gaining strength
through incremental improvements• Intranets and extranets growing
Higher education needs a production Internet capable of serving mission-critical applications• and so does the rest of the world!
Internet2 implements advanced capabilities
Next Steps
Continue to interconnect member desktops and servers at high speed
Continue to support advanced applications development• focus on multi-campus implementations
Adopt, develop and implement • QoS end-to-end• middleware end-to-end• new business models
Abilene
Objectives for the Abilene Network
High availability backbone network for advanced research applications
Separate network to test advanced network capabilities
Quality of Service standards to guarantee types of availability
Multicasting and advanced security “Separate network” to do
network research
Progress
Demonstrated September 1998 In production January 1999 Add participants during 1999 Agreement to peer with vBNS,

The QBone Initiative
What is “the QBone” Vision
• Significant subset of the Internet implements well-defined notions of QoS and is regarded by users as infrastructure
Testbed• Interdomain DiffServ testbed being built by R&E
networks• Infrastructure only a graduate student could love
Initiative• Internet2 initiative that includes
QBone testbed (QIG) Intradomain solutions group (QSG)
QBone Call for Participation
CFP issued September 25th, 1998 Proposals due October 16th Review complete October 30th Participant Types
• Networks• Network Engineering / Advanced
Development• Applications and Middleware Developers• Corporate Partners
Initial Participants
13 Proposals recommended for initial QBone Interoperability Group (QIG)• Abilene• CAnet*2• iCAIR Consortium
APAN, CTIT, EVL, Indiana University, MREN, Nanyang Technological University, National University of Singapore, Northwestern University, SingAREN, STAR TAP, SURFnet, TransPAC
Initial Participants (QIG) - cont’d• IPPM Surveyor Project• Merit / University of Michigan• NCNI - North Carolina Network Initiative• NREN• NYSERNet• PSC / NLANR / CMU• Texas A&M University / Texas GigaPoP• UMN• UPenn/ UMass• vBNS
QBone Structure QBone Interoperability Group (QIG)
• Actively building pre-production interdomain DiffServ infrastructure
• Works on nuts-and-bolts interoperability issues
• Specific phased demonstrations of interdomain QoS
• Participation staged to keep group focused
QBone Structure -cont’d QBone Solutions Group (QSG)
• Broader discussion of engineering and deployment issues
• Includes teams that plan to join the QIG• Focus on intradomain engineering issues• Participation open to the Internet2 community
I2 QoS Working Group• Architectural guardians• Nurture QIG and QSG

Middleware
Middleware Challenges
Identify technologies that are scalable and interoperable
Increase deployment of middleware technologies as part of a pre-commercial production environment
Examples:• Distributed storage - I2-DSI initiative• Multicast video tools - I2-DVN initiative
Applications: Horizontal, Vertical, Spot Solutions
Middleware:Security, Directory, Quality of Service,Audio/Video Frameworks, Accounting,Collaboration Frameworks, Multicast
Operating system and network services
Standard APIs
Standard APIs
Interoperable Protocols
Technology Scope
Emphasis is on technologies that enable developing and deploying advanced research and education applications across our institutions
Technology Scope
QoS Digital video/audio Security Collaboration Directories Multicast File systems Measurement Remote instruments IMS
Transaction systems Meta-computing Management IP telephony Accounting/billing E-commerce Object brokers Search mechanisms Printing
Initiative Overview
Deliverables
•Identification of a small number of key community projects
•Information dissemination•Demos •Workshops
Principles
Focus on problems where
•we have a unique incentive to solve
•the benefit to our community is clear and compelling
•results are attainable in a reasonable timeframe
I2-Digital Video Network
Ubiquitous Digital Video
Scalable and easy to use
Integrated into applications Streaming and interactive Real-time and asynchronous (stored) Unicast and native multicast Single source to multi-source Resolutions up to HDTV
Distributed Storage Initiative
Objective
Develop and deploy a reliable, scalable, high performance network storage capability enabling broad access to stored video, very large data sets, etc.
Internet2 in a global context
Internet2 International Collaborations
Building peer to peer relationships Looking for similar goals/objectives and
similar constituencies Mechanism: Memoranda of Understanding Signed: CANARIE, Stichting SURF,
NORDUnet In process: TERENA, SingAREN, JAIRC,
APAN and others
Focus and Goals Enable collaboration between researchers and
educators Ensure global interoperability of advanced
technologies Interconnect high-performance networks
• Abilene <-> CA*net II/3 interconnection/peering agreement
Deploy QoS and other technologies across networks• CANARIE participation in QBone initiative• Joint working group meetings between CANARIE and
