Interconnection WG Plans and Activities
  • -- what interested in?
  • all things interconnection related so
  • -- QoS (congestion mgmt), Net Mgmt
  • -- ISP interconnection
  • -- Access regulation/architecture
    (e.g., NN, BB)
  • -- Traffic analysis (e.g, MITAS)
  • -- Other stuff IPv4/IPv6, demand
    scenarios,
  • -- what have we been working on
  • Sorting out Internet Capacity Sharing A Roadmap
    Towards Congestion Transparency
  • -- Working mode
  • 2 mail lists general, working
  • monthly teleconference (at regular time)
    talk paper
  • next face-to-face maybe next spring..
    where? Adjacent to next CFP meeting
  • EMAIL WLEHR_at_MIT.EDU (if want to
    participate, be added to list)

Sorting out Internet Capacity Sharing A
Roadmap Towards Congestion Transparency
  • -- Bob Briscoe (BT) et al. ? Congestion
    management for general Internet
  • -- ECN/re-ECN roadmap
  • How to implement raise awareness, mobilize
    support, first steps
  • Further IETF standards (congestion
    exposure wg, Oct09)
  • On path to usage-sensitive data charging
  • -- Basic idea how to get right information to
    support better resource sharing
  • We measure volume of traffic but what drives
    costs is peak traffic (congestion)
  • Better info exchange between end-users-ISP,
    ISP-ISP, and everyone else

Message share congestion information with
end-users, with network
  • -- Underlying issue is capacity sharing (good
    thing!) but how?
  • -- Incentivize good behavior by end-users,
    apps/OS, and networks (with everyone.)
  • - Is transparency way to do this? Does it
    address incentives?
  • (- do we need to define good? A
    competitive market assumptionor, TCP-fairness
    is good or not.
  • depends on viewer do not prejudge
    bargaining outcome that should occur.)
  • -- Allow Internet to understand how to talk about
    and have common view of congestion like today it
    has about traffic volume.
  • -- If cannot measure it, cannot manage it..
  • - Managing is good something we need to
    convince FCC is at least not bad.
  • (those who view as bad may believe
    exposing congestion makes bad by ISPs more
    likely. One response is that ISPs already doing
    it but badly which is worse.)
  • -- Who needs to share information? What are
    scenarios for use of info? (deployment?)
  • - Who needs to know what?
  • - End-users already know when they
    are congested (TCP does that)
  • - Network does not know what end
    users are seeing
  • - Network needs to see aggregate
    picture of congestion
  • - Who should share with whom?
  • - End-user (App? OS?) and (access)
    ISP allow ISPs to see what end users see?
  • - ISP-ISP to make it usablemust
    cross ISP boundaries
  • - (w/ Policymakers? 3rd parties?
    Market?) (Transparency issue?)
