Abstract: A system for bilaterally transferring information between a client and a remote server. The client is coupled with a server proxy running on a second receive server via a first network and communicates thereon. Processed first information is passed to a first send server via a dedicated network connection. The first send server causes the first information to be transmitted to the remote server, via a first one-way data link, a first receive server, a second dedicated network connection and a client proxy running on a second send server. The remote server is coupled to the client proxy via a second network. The client proxy forwards information received from the server to the client via a second one-way link, the server proxy running on the second receive server, and the first network.

Abstract: A system for bilaterally transferring information between a client and an NFS server. The client is coupled with an NFS server proxy running on a second receive server via a first network and communicates thereon. The processed first information is passed to a first send server via a dedicated network connection. The first send server causes the first information to be transmitted to the NFS server, via a first one-way data link, a first receive server, a second dedicated network connection and an NFS client proxy running on a second send server. The NFS server is coupled to the NFS client proxy via a second network. The NFS client proxy forwards information received from the NFS server to the client via a second one-way link, the NFS server proxy running on the second receive server and the first network.

Abstract: A method of providing reset logic in high availability computer systems is disclosed. The illustrative embodiment of the present invention uses probability theory in combination with redundant processors and components to ensure system availability. Detected errors are verified, and malfunctioning processors or components are then changed to a reset state that functionally removes them from the system. Detected errors which can not be verified result in the processor or component that incorrectly detected the error being placed in a reset state. The use of redundant components and processors enable standby processors to be activated to take the place of reset processors quickly enough to maintain system availability.

Abstract: A method for maintaining a timed event list is disclosed. The illustrative embodiment of the present invention provides a method of rapidly inserting, examining, rescheduling and executing events in a timed event list in a time critical manner. By limiting the time required to insert events into a timed event list, and further limiting the time required to retrieve events from a timed event list, the method of the present invention increases the time available to a system to process timed events.
