Main Goals

Based on the discussion last class, what I think the focus of the project should be is what are the kind of things that fundamentally should be a "public good" as opposed to exactly how to implement them. Some of the ideas we have come up with can be used for various implementations but I think, in general, we can rely on previous work for most of (if not all) of the implementation details. If this assumed direction is correct, then I think we should aim to try and answer the following questions:

• What are good candidates for public goods (ie. DNS, internet cache, physical connections, etc)? Why should these services be fundamentally controlled by the public? What are the flaws in the way they are currently used or why should they not be centrally controlled by a single entity? What incentives are there for a given user to participate (willingly or unwillingly)?
• What would be the net benefit for the local community participating in these public goods?
• What would be the net impact on the entire internet if all local communities created these public goods (more secure, less bandwidth wasted, etc.)
• After identifying some candidates for public goods, try and determine what is the commonality between these services, in problem, in alternative? What are some things that are fundamentally different about these goods?

Note to prof: Please let us know if you have any comments on the overall direction we are taking the project.

Potential Topics

• What else occurs on the internet
  • physical infrastructure (phoneline, cable, satellite, etc)
  • DNS, BGP, ----
  • TCP/IP, UDP
  • HTTP, SMTP, POP, IMAP, FTP, SSH
  • email = SPAM, search, internet caching

Note to prof: This is still a working list, but if you notice anything that we should definitely try to cover that we haven't thought of, please let us know.

Current Work

• Fahim - DNS

Candidates for Public Goods (Use this area to post your ongoing work)

Physical Infrastructure (Lester)

• BGP - this could be more important as well when replacing the current physical internet. Some routing federation would be need though http://en.wikipedia.org/wiki/Border_Gateway_Protocol
• Virtual Structure Freenet - http://en.wikipedia.org/wiki/Freenet
• Tangent - Antispam techniques http://delivery.acm.org/10.1145/1460000/1455525/a13-xie.pdf?key1=1455525&key2=3831189921&coll=DL&dl=ACM&ip=134.117.254.248&CFID=11136817&CFTOKEN=58039805

Caching (Andrew)

Relevant Papers & Links

• A Survey of Web Caching Schemes for the Internet background
• Should Internet Service Providers Fear Peer-Assisted Content Distribution?
• Energy-Efficient Caching Strategies in Ad Hoc Wireless Networks Could tie in with the infrastructure stuff.
• Taxonomy and Design Analysis for Distributed Web Caching
• [1]

Misc Notes

• look into LAN caching. if we proposed a new infrastructure where neighborhoods are networked, caching can be done here.

DNS (Fahim)

Google Public DNS: Good for privacy?

Google Public DNS: Wonderful Freebie or Big New Menace?

Free Fast Public DNS Servers List

With free, public DNS, where is this information about user behaviour going, if anywhere? Is this an example of a good that should be managed by a central/public/democratized authority?

The Design and Implementation of a Next Generation Name Service for the Internet I came across this paper while looking around, might be interesting. -Andrew
