Proposed APAN I2 QBone Activities

1
Proposed APAN I2 QBone Activities

• CCIRN QoS WG
• _at_ Orlando IETF43
• Tuesday, 8 December 1998
• Doug Pearson (dodpears_at_indiana.edu)
• Kazunori Konishi (konish_at_lab.kdd.co.jp)

2
Caveats

• This presentation is
• not representative of the entire range of APAN
  QoS activities
• premature - refined plans will be developed in
  the coming weeks

3
Participation in the I2 QBone

• ...within the context of the Joint Proposal
  organized by the International Center for
  Advanced Internet Research (iCAIR).

4
Joint Proposal - Participants

• APAN - Asia Pacific Advanced Network
• Centre for Telematics and Infomation Tech., U of
  Twente
• Electronic Visualization Laboratory, University
  of Illinois, Chicago
• IBM Thomas Watson Research Center
• iCAIR/Northwestern University
• Indiana University
• KDD - Kokusai Denshin Denwa Co. Ltd.
• Korea Telecom
• MREN - Metropolitan Research and Education
  Network
• Nanyang Technological University
• National University of Singapore
• SingAREN
• STARTAP
• SURFnet
• TransPAC

5
Joint Proposal - Objectives

• Develop an optimal design and early
  implementation of of state-of-the-art QoS
  concepts within an international testbed linked
  to the I2 networks.

6
Joint Proposal - Objectives

• establish a cooperative international effort to
  address issues of
• common understanding of QoS design
• definition of types and priorities of
  applications and required resource guarantees
• management policy options for differentiation of
  service categories, distributed governance and
  resource allocation mechanisms across multiple
  domains

7
Joint Proposal - Objectives

• establish a cooperative international effort to
  address issues of
• baseline standards, reference configurations and
  dependability parameters for auditing performance
  to contract
• common appropriate response to non-compliance and
  priority conflicts
• bandwidth brokers
• policy servers

8
Joint Proposal - Applications

• streaming digital video - I2 DVN
• persistent infrastructure to provide high-quality
  digital video services in the Internet2 community
• live and stored content
• IBM VideoCharger technology
• multicast
• MPEG1 and MPEG2 at data rates up to 8 Mbps
• directory services
• large file systems
• caching and replication
• requirement for QoS

9
Joint Proposal - Applications

• TeleImmersion
• based on previous experiments of the STAR TAP
  TeleImmersion Experiments between EVL and the
  Institute of High Performance Computing at the
  National University of Singapore
• merging of audio and video conferencing with
  collaborative virtual reality

10
Joint Proposal - Network

• spans from Asia-Pacific through the US to the
  Netherlands
• APAN
• CTIT
• IBM research center
• MREN
• SingAREN
• STAR TAP
• SURFnet
• TransPAC
• campus networks

QoS Implementation and Research

• mechanisms
• experiments to study the effect of AF and EF PHBs
  on application performance
• Cisco mechanisms of CAR, DWRED and WFQ
• absence of mechanism to perform traffic shaping
  on egress??

13
QoS Implementation and Research

• measurement
• behavior of individual and aggregate flows and of
  mechanisms, e.g. queueing, discard...
• IPPM measurement probes
• RTFM at selected sites
• end-to-end RTCP feedback
• OC3mon?
• multi-domain
• SLAs (Service Level Agreements)
• TCAs (Traffic Conditioning Agreements)

14
QoS Implementation and Research

• brokers
• AAA
• participate in development of bandwidth brokers
• the whiteboard interdomain bandwidth broker
• policy control functions coupled with admission
  control

15
QoS Implementation and Research

• network management
• investigate what management information needs to
  be exchanged between domains
• contribute to development of MIBs
• investigate the problem of accounting
• auditing of performance to contract
• second order effects
• concern multicast is not addressed

Closing

• CCIRN-QoS group should encourage its member
  networks to collaborate with Internet2 QBone
  project
• Other CCIRN groups such as measurement and
  multicast should help Internet2 QBone for global
  collaborations/operations
