The secondary virtual machine is operable to replicate the primary virtual machine by replicating operations performed on the primary virtual machine. The primary and the secondary virtual machines are further operable to test for equivalent operation of the primary and secondary virtual machines at predetermined stages of operation. This provides software fault tolerance wherein both a unit of replication and a component that implements the fault tolerance mechanisms is a virtual machine (VM). Since a VM as used by the invention has full knowledge of the semantics of application-level code, fault tolerance mechanisms can be provided by the VMs without requiring any increase in application complexity. Co-ordination of replicated states and computations is achieved with characteristics of both active and passive replication. -------- http://www.rctophobby.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=405544#405544 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message avionics-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Avionics-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/avionics-list Browse Digests http://www.matronics.com/digest/avionics-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
