Internet2: Developments and Directions

CANARIEThird Annual Advanced Networks WorkshopDecember 15-16, 1998

Doug Van Houwelingdvh@internet2.edu

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

QBone Milestones Sep 25th - call for participation issued Oct 27th - QFC met to finalize

recommendations Nov 30th - 1st Meeting of QBone BB Advisory

Council Dec 1st - QBone Networking Kickoff Meeting Jan 1st - Revised QBone Architecture from

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
