[jboss-jira] [JBoss JIRA] Commented: (JBCACHE-971) Eviction policy based on adaptive replacement

[ http://jira.jboss.com/jira/browse/JBCACHE-971?page=comments#action_12416943 ] Paul Cowan commented on JBCACHE-971: ------------------------------------ For the record (Manik's recent target version change reminded me to update this): I have now developed a cache library which includes implementations of the following algorithms: * ARC * FRC (non-self-adjusting version of ARC; not sure if this is covered by the same patents as ARC) * 2Q * MQ (Multi-Queue Replacement, by Zhou, Philbin and Li -- see http://www.usenix.org/event/usenix01/full_papers/zhou/zhou_html/index.html -- I am not sure if there are any patent encumbrances here, and have contacted 2 of the authors to try and find out) This library has been developed without being jboss-specific; I have produced an adapter for JBoss Cache 1.3 (which we're still stuck using) and then one for JBoss Cache 2.0, which I would be happy to contribute (my employer has given me permission to do so, and is in the process of formalising this internally). HOWEVER, I have not heard anything back from IBM in the last 5 months in relation to the ARC patent issues, which makes me loathe to release this (of course!). Is there anyone at JBoss who would be in a better position to shake the IBM tree and try to extract an answer? I would be very keen to release my library and think JBoss Cache would benefit from it. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
