Abstract: This paper designs a publish-subscribe system which adopts a hybrid mode of publish-subscribe and point-to-point message passing paradigm based on CORBA.The principle and fundamental architecture are interpreted. The working process is described followed by the features and merits. The implementation based on TAO/ACE is provided before the future work is put forward.
