I wouldn't bother, it is flawed.  That paper proposes to replace LRU  
cache replacement with a mechanism that artificially enforces a  
Kleinberg link distribution, but have failed to realise that LRU  
cache replacement already achieves this in a much more natural and  
elegant manner (we have found this experimentally, and Oskar has been  
working on explaining this mathematically, with positive early results).

IIRC Oskar suspects that the authors of this paper's observed  
improvement in performance is much more likely to be due to the fact  
that their algorithm was better at ensuring the presence of short  
links in their experiments than LRU - but not that LRU wasn't  
achieving a Kleinberg link distribution.
