Topology

SLIDE 16

Topology

www.ratemynetworkdiagram.com

Topology shouldn’t matter, but it does

  • “Inside” versus “outside”
  • Multiple DHCP servers
  • Multiple subnets (breaks multicast discovery)

It’s not just the end-user devices, but network core devices that users must manage

slide-17
SLIDE 17

Security

“If you want security, you must be prepared for inconvenience.” General B.W. Chidlaw

12 December 1954

  • Conflated with topology
  • Spread over multiple sites of

activity (antivirus, host firewall, router firewall, ISPs)

  • Default for most: NAT

This has let us get sloppy.

slide-18
SLIDE 18
  • Does the network really stop at the “application

layer”?

  • Infrastructure doesn’t provide good abstractions

for some functionality

  • Multiuser game?
  • Household visitor?
  • Share a directory of photos?

Interactions Between Applications and the Network

End Result?

  • High pain barrier: even “simple” things

are hard; hard things are nearly impossible

  • High barriers, low ceilings
  • Implications for future applications

inhibited because of fundamental issues with the network:

  • Health
  • Entertainment
  • Ubicomp
  • Smart home
  • Smart grid
  • ...

Motivation

  • The network is a means to

an end.

  • In other words:
  • People want what the

Internet affords.

  • They just don’t want the

network. “We want the Internet. Unless you have something better.”

Deeply Personal, Deeply Personalized

  • Is a one-size-fits-all network even possible?
  • High variance may make automating

some aspects difficult

  • May argue against “outsourcing”

“Home Networking and HCI: What Hath God Wrought?” [CHI 2007] “How Smart Homes Learn: The Evolution of the Networked Home and Household” [Ubicomp 2007]

slide-27
SLIDE 27

End Result?

  • We’ve made networking a deeply confusing affair
  • “Scary” upgrades, reboot-and-pray troubleshooting,

blinky light user interfaces

  • One-size-fits-nobody
  • Neither sufficiently understanding nor addressing the

routines in the household that impact the network

Some Reflections

  • n the Gap
slide-29
SLIDE 29

The Disciplinary Divide

  • The usual: different language, goals, methods,

value systems, conferences, ...

  • Neither discipline reaches far enough, or has

the right tools to allow it to sufficiently integrate with the other

Helping the Network Help Itself

  • There will always be some aspects of

networking that require human agency or control

  • But for everything else, can we make it just

work?

  • Key: knowing what's in which category

“Moving Toward the Middle: The Case Against the End-to-End Argument in Home Networking,” [HotNets, 2007]

Helping People Help Themselves

  • What’s the equivalent
  • f the desktop

metaphor for networking?

  • Not just a UI
  • problem. Also may

require support from the network in order to do it well.

Helping People Help Each Other

  • Collaboration is key
  • How do we support with tools?
  • Deep questions around personalization and privacy
  • Opportunities to leverage social networks to help

with computer networks?

One Last Thing...

  • Know of any good students interested in a

postdoc working on home networking stuff at Georgia T ech?

  • Knowledge of OpenFlow and network

measurement, good Linux skills, and enthusiasm for working with HCI people a plus
