Technical Innovation Quality of Service

• Chair Ben Teitelbaum, Internet2 staff
• Focus Multi-network IP-based QoS
• Relevant to advanced applications
• Interoperability carriers and kit
• Architecture
• QBone distributed testbed

33
Big Problem 1 Understanding Application
Requirements

• Range of poorly-understood needs
• Both intolerant and tolerant apps important
• Many apps need absolute, per-flow QoS assurances
• Adaptive apps may require a minimum level of QoS,
  but can exploit additional network resources if
  available

34
Big Problem 2 Scalability

• flows through core gtgt flows through edge
• Goal keep per-flow state out of the core
• Design principles
• Put smarts in edge routers
• Allow core routers to be fast and dumb

35
Big Problem 3 Interoperability
... between separately administered and designed
clouds ...
Backbone Networks(vBNS, Abilene, )
and between multiple implementations of network
elements ...
is crucial if we are to provide end-to-end QoS.
36
Premium Service

• Emulates a leased line
• Contract peak rate profile
• PHB forward me first (e.g. priority queuing,
  WFQ)
• Policing rule drop out-of-profile packets
• On egress, clouds need to shape Premium
  aggregates to mask induced burstiness
• GigaPoPs
• scalable access to wide-area resources
• Backbones
• vBNS
• Abilene

What is NGI?

• The goal of the NGI is to conduct RD in
  advanced networking technologies, to demonstrate
  those technologies in testbeds that are 100 to
  1,000 times faster than todays Internet 1
  megabit/sec, and to develop and demonstrate on
  those testbeds revolutionary applications that
  meet important national needs and that cannot be
  achieved with todays Internet.
• In essence to let our researchers live in the
  future.

  their national networks and their international
  connectivity
• I have picked two presentations (Italy and
  Germany) to illustrate some points.
• Common themes are Gigabit testbeds and plans,
  QoS/Differentiated services
• Idea of justified use vs. general Internet

Some personal comments (1)

• USA
• General Internet (old news by now, buy it)
• Mission specific (ESnet, I2, NGI?)
• Europe
• National networks European network
• No mission specific anymore ?
• Who drives initiatives ? On Gbit, on peering
• Europe-ESnet / Europe-I2 ???????
• Europe ?? TEN-155 or Europe ?? Natl netwks
• DANTE very quiet during the meeting

69
Some personal comments (2)

• Focus on applications needs people to make
  proposals in which forum are they dicussed ?
• Network to network peering
• Agreements (e.g. with NSF, etc.)
• Membership (e.g. membership in UCAID)
• Interesting coffee conversation item
• Coming to Paris to meet with the Americans turns
  out to provide a good (the only??) forum for
  Europeans to exchange views
