i started an index of filesystems, awhile back. afs, bfs, cfs, dfs, etc..
This project is aimed at developing algorithms and implementation techniques to build practical Byzantine-fault-tolerant systems, that is, systems that work correctly even when some components are faulty and exhibit arbitrary behavior. We believe that these systems will be increasingly important in the future because malicious attacks and software errors are increasingly common and can cause faulty nodes to exhibit arbitrary behavior.
i’m still more intrigued by peer-to-peer backup systems. examples i’ve found are:
pStore, an mit paper
dibs, a python-based package using a custom erasure correcting implementation
dbs, an abstract at ucalgary
exercising dhash with distributed backup[.ppt], another mit thing built on chord
secure distributed document storage through peer-to-peer technology [.pdf], an ibm zurich effort
dbackup, a jini-based project that doesn’t even appear to be in the planning phases
and while they may not meet the definition of peer-to-peer, these are projects i’ve been watching:
oceanstore, oceanstore is to storage as now.cs is to computing
koh-i-noor, check the ppt slides — they were going to solve “the hotmail problem”
my worst fear incarnate — Web E-Mail: The New Hard Disk (Jeremy Zawodny’s blog)
the domain name (phong.com) makes me want to grab a newer pov-ray and play with all the features added since i knew it. radiosity wasn’t implemented in the ‘stable’ release when i used it.
