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?)
