Title: Tussle in Cyberspace:


1
  • Tussle in Cyberspace
  • Defining Tomorrows Internet
  • by
  • David D. Clark, John Wroclawski
  • Karen R. Sollins, Robert Braden
  • Offense Ionut Trestian

2
Main outlines from paper
  • Accommodating choices into Internet design
  • Allows innovation
  • Allows tussles to occur
  • Gives flexibility for designers and customers (is
    flexibility really the most important thing ?)?

3
168 Citations ?
  • It must perform appropriately in the presence of
    conflicting or inconsistent higher-level goals
    among the Internets different stakeholders. This
    is a manifestation of the tussle dilemma
    discussed in
  • competing solutions to human-friendly naming,
    thereby allowing the resulting tussle to play
    out through legal and other social channels
  • Citations substance it seems that the only
    merit of this paper is introducing the term
    tussle
  • What was actually the aim of the paper?

4
Issues with paper (1)?
  • It talks more about philosophical issues without
    any technical advise
  • Discuss ethical questions without clearly stating
    the assumptions or value systems (again, is
    flexibility the most important metric ?)?
  • Lacks coherence, discusses complex issues,
    However sometimes dives into lots of details like
    Source routing, firewalls etc
  • Things discussed here not new, actually well
    known by the community (QoS, multicast ...)?

5
Issues with paper (2)?
  • Intellectual property issues are important
  • But why only when they involve small potatoes
    like me downloading the new Britney Spears video?
  • What about patent issues between big companies,
    isn't that a tussle?
  • Which of the two causes more harm?

6
Issues Flexibility
  • Flexible designs will be complex
  • Applications need to deal with this complexity
  • Innovative applications actually come out but
    slowly.
  • Other metrics need to be considered too
    (availability, price)?

7
Issues Designing for outcome
  • Paper says Do not design so as to dictate the
    outcome
  • How can a design proceed without a goal in mind?
  • Design of the Internet based on packet in
    packet out functionality..very simple and not
    designed for any outcome
  • ... packets go in and come out and this is all
    that happens in the network. This simple idea was
    powerful in the early days.. but there is much
    fear that it seems to be eroding..
  • What should happen in the network?

8
Issues User choice
  • Too many choices don't make a user happy.
  • Average user will actually be confused by too
    many choices and their consequences.
  • It favors the technical savvy and ...
  • ..we may see the emergence of third parties
    that rate services (the online analog of
    Consumers Reports) and parties that provide
    pre-configured software to relieve the user of
    dealing with the details of choice ...

9
Issues User choice
  • Providing more choices is costly
  • Popular choices will get cheaper (Economies of
    scale)?
  • Users of less popular choices will need to pay
    more
  • One should be prepared to pay for what one uses
    or there is very little incentive for the
    provider to offer it

10
Apocalyptic warnings
  • Internet prices will increase in 5 years due to
    lack of competition - 2002 (2008 now and didn't
    really happen we're actually getting more bits
    per buck)?
  • Municipal deployment of fiber? Not happening at a
    large scale.

11
Finally
  • Transport layer provides choice TCP/UDP, even
    more.
  • IP-lock in is addressed by DHCP and NATs
    (maybe still a problem if you are a service
    provider DNS issues).
  • Loose source routing is addressed by overlay
    routing.
