1?Topic
The?ADAPTIVE?Communication?Environment?(ACE)?is?a?C++?toolkit?for?object?oriented?network?programming?that?has?been?developed?at?the?Washington?University?of?St.Louis,?MI,?USA?by?Douglas?C.?Schmidt.?Since?the?early?days,?it?addresses?high?performance?environments,?such?as?medical?imaging,?avionics?and?telecommunication?applications.?ACE?incorporates?an?operating?system?abstraction?layer?that?facilitates?porting?of?applications?to?different?platforms?(several?UNIX?flavours,?WindowsNT,?LynxOS?and?VxWorks?to?name?but?a?few).?On?top?of?this?layer?design?patterns?that?are?common?to?network?aware?applications?have?been?implemented.?ACE?contains?also?a?real-time?CORBA?implementation?named?TAO.
