Presentation Transcript

  1. 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@MIT.EDU (if want to participate, be added to list)

  2. “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

  3. Backup slides…

  4. Authors Authors are individuals with company affiliation noted, but disclaimer stating views are not those of company but author alone. Who here but has not been participating? (e.g., Murari) (Who do we want that not here? Who participating but not here? (e.g., Kwok Chan)

  5. Outline

  6. 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 assumption…or, “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 usable…must cross ISP boundaries… • - (w/ Policymakers? 3rd parties? Market?) (Transparency issue?)
