Secure bidirectional cross-system communications framework
View Patent ↗A local computer system and a remote computer system are connected by a network. When the local computer system needs to initiate communication with the remote computer system or vice versa, a cross-system request is generated, and placed in a request queue on the computer system generating the request. All cross-system requests residing on request queues and are handled by two jobs executing on local computer system. The first of these jobs, a request push job, pushes cross-system requests existing on local computer system's request queue to the remote computer system's request queue. The second of these jobs, a request pull job, pulls cross-system requests existing on remote computer system's request queue over to local computer system's request queue. In this way, all cross-system communications are initiated from a computer system inside the firewall (e.g., local computer system) without violating any outside-in dataflow limitations.
1. A method of secure bidirectional cross system communication between one or more local computer systems and one or more remote computer systems comprising the steps of:
initiating a request push job on at least one of the one or more local computer systems for pushing a cross-system request from the one or more local computer systems to a request queue on the one of the one or more remote computer systems; and,
initiating a request pull job on at least one of the one or more local computer systems for pulling a cross-system request from the one or more remote computer systems to a request queue on the one or more local computer systems;
wherein the request push job further comprises:
initiating a connection with the one or more remote computer systems;
notifying the one or more remote computer systems that a local-to-remote communication will occur,
checking the first request queue for any cross-system requests destined for the one or more remote computer systems;
sending any cross-system requests destined for the one or more remote computer systems to the one or more remote computer systems; and,
processing the cross-system request at the one or more remote computer systems.
2. The method of claim 1 wherein the step of sending any cross-system requests to the one or more remote computer systems further comprises placing the cross-system request into the request queue on the one or more remote computer systems.
3. The method of claim 1 wherein the step of processing the cross-system request further comprises:
reading an application file on the remote computer system to determine which application queue the cross-system request will be routed to;
routing the cross-system request to an application queue using a request router job;
temporarily storing the cross-system request in the application queue until the cross-system request is processed by an application; and,
removing the cross-system request from the application queue and processing the cross-system request using the application.
4. The method of claim 1 wherein the request pull job further comprises:
initiating a connection with the one or more remote computer systems;
notifying the one or more remote computer systems a remote-to-local communication will occur;
checking the second request queue for any cross-system requests destined for the one or more local computer systems;
sending any cross-system requests destined for the one or more local computer systems to the one or more local computer systems; and,
processing the cross-system request at the one or more local computer systems.
5. The method of claim 4 wherein the step of processing the cross-system request once it has been sent from the one or more remote computer systems to the one or more local computer systems further comprises:
reading an application file on the local computer system to determine an application queue the cross-system request will be routed to;
routing the cross-system request to the application queue using a request router job;
temporarily storing the cross-system in the application queue request until the cross-system request is processed by an application; and,
removing the cross-system request from the application queue and processing the cross-system request using the application.
6. The method of claim 1 wherein the step of sending any cross-system requests to the one or more local computer systems further comprises placing the cross-system request into the request queue on the one or more local computer systems.
7. A method of enabling a local computer system for secure bidirectional cross system communication between the local computer system and a remote computer system comprising the steps of:
initiating a request push job on the local computer system for pushing a cross-system request from the local computer system and adapted to be received by a request queue on a remote computer system; and,
initiating a request pull job on a local computer system for pulling a cross-system request from a remote computer system and adapted to be received by a request queue on the local computer system;
wherein the request rush job further comprises:
initiating a connection with the remote computer system: notifying the remote computer system that a local-to-remote communication will occur,
checking the first request queue for any cross-system requests destined for the remote computer system: and
sending any cross-system requests destined for the remote computer system to the remote computer system.
8. The method of claim 7 wherein the step of sending any cross-system requests to the remote computer system further comprises placing the cross-system request into the request queue on the remote computer system.
9. The method of claim 7 wherein the request pull job further comprises:
initiating a connection with the remote computer system;
sending a notification to the remote computer system that a remote-to- local communication will occur;
checking the second request queue for any cross-system requests destined for the local computer system;
receiving any cross-system requests destined for the local computer system; and,
processing the cross-system request at the local computer system.
10. The method of claim 9 wherein the step of receiving any cross-system requests at the local computer system further comprises placing the cross-system request into the request queue on the local computer system.
11. The method of claim 9 wherein the step of processing the cross-system request once it has been received at a local computer system further comprises:
reading an application file on the local computer system to determine an application queue the cross-system request will be routed to;
routing the cross-system request to the application queue using a request router job;
temporarily storing the cross-system in the application queue request until the cross-system request is processed by an application; and,
removing the cross-system request from the application queue and processing the cross-system request using the application.
