Topics for iWORK 2005(st)

Topic #1 Title: ”The rise of peer-to-peer networking: implications to carriers and associated strategies” Background: P2P applications have been responsible for a significant shift in Internet traffic profiles, possibly also contributing to the popularity of broadband connections among consumers. If not managed properly, however, this traffic can choke the connections associated with other applications (including traffic from other subscribers). Goal: Find out what public information is available regarding the impact of P2P applications on Internet traffic. What conclusions can be drawn from these results? What methods can be used to monitor P2P traffic? How can P2P traffic be identified? Find out and evaluate the different ISP strategies for handling P2P traffic. What products are available in the market? What are their features?

Topic #2 Title: ”Evolution of Peer-to-peer algorithms: Baseline, state of the art, and future directions” Background: P2P computing can be traced back to the early days of the ARPAnet (1960s). It took until the late 1990s until the first mainstream P2P application emerged. Several more followed, and still more are expected to emerge… Goal: identify and give an overview of the key technological innovations have sustained the success of P2P applications. How have the protocols underlying P2P applications evolved? What are the main variants of P2P protocols in use today? What features (e.g. efficiency, reliability, anonymity, etc…) is the research community still working on? How will these features enable new/improved P2P applications?

Topic #3 Title: ”IP telephony: client-server vs. peer-to-peer approaches” Background: One interesting application of P2P technology is in the area of IP telephony. P2P telephony does not exhibit the copywrite issues which are associated with earlier P2P applications such as content distribution. Goal: Compare the client-server (SIP), and peer-to-peer (e.g. Skype) approach for IP telephony. Can IP telephony be pure peer-to-peer? What features need to be centralized? Include an overview of [2] in your analysis. You can also cover aspects related to the open (SIP) vs. proprietary approach (Skype).
