Well, I just did a default install of freenet and I see that the defualt store size is still only 256MiB. Right now the network is seriously overloaded and bandwidth is scarce; tiny data stores compound the problem. If you have a good reason for such a tiny default datastore size, I'd love to hear it. The second area, is bandwidth limiting. Right now, I notice that my node, even though it has >20MB or data wating to be sent, the upstream bitrate varies from about 1/2 to 3/4 of the vaule of my upstream bandwidth limit. If 3/4 of the limit is the maximum, then why doesn't my node send data at a constant rate at the maximum bandwidth limit specified? I turned off bandwidth limiting and the node transmitted at the limit of my upstream speed and stayed there without slowing down even slightly. Optimizations in the bandwidth limiting would help maximize the performance of the network.
One other thing, I read on article in Scientific American (May 2003, pages 60-69)about scale-free networks that was quite interesting. Intuitively, it seems that freenet is a type of scale-free network itself. One of the weaknesses of these types of networks is that they are vulnerable to attacks on hub nodes. My concern is the global mean traffic stat that is associated with each node. An attacker could gather information about the network and use these statistics to identify the hub nodes in the network. The attacker would then have a better chance of disrupting the network by focusing an attack on this subset of nodes. How likely is this? Is it a concern for the developers? __________________________________ Do you Yahoo!? Yahoo!
