10/28 Update

The group met before class on Saturday and discussed the tasks proposed by Lucy. Then, we decided to assign each task to a group member. Accordingly, the tasks are:

Task 1 Initiation process by Lucy Holman Rector

Task 2 Read information about the Landscape items, writing comments, submitting files by Lesley Humpreys

Task 3 Get the riddle and find the mystery object by Bill Discher.

Task 4 Check out the sites captured and submit them to teacher or to relevant place by Hamza Tosun.

Details about the tasks are available at the wiki page. Each of us agreed to prepare a prototyping draft for the interfaces of the tasks and bring them to the next group meeting, which will be held this Saturday (10/28).

I am sorry for the previous message about peer to peer sharing. Please disregard it that would be posted to another blog.

A Measurement Study of Peer-to-Peer File Sharing Systems

http://www.cs.toronto.edu/~stefan/publications/mmcn/2002/mmcn.html

At this link, you can find an interesting research on a measurement of peer-peer sharing systems, namely Napster and Gnutella. In that paper, researchers illustrate the infrastructure of the systems as well as the topology of the Gnutella Network (as of February 16, 2001). According to the results of the research, they reach this interesting conclusion:

“Another myth in P2P file-sharing systems is that all peers behave equally, both contributing resources and consuming them. Our measurements indicate that this is not true: client-like and server-like behavior can clearly be identified in the population. As we have shown, approximately 26% of Gnutella users shared no data; these users are clearly participating to download data and not to share. Similarly, in Napster we observed that on average 60-80% of the users share 80-100% of the files, implying that 20-40\% of users share little or no files.”
