Abstract

A method and apparatus is provided to discover and integrate applications in an application router framework. The discovery operation includes receiving a registration notification for an application on a network, adding information describing the application to a repository into a data structure and publishing the data structure onto an application router. The association operations include querying one or more application routers on an application network for meta-data and other information on applications, exchanging the meta-data and other information between the application routers and associating the applications together automatically using their respective application protocols. Routing operations include receiving application information in an application protocol format, converting the application information in the application protocol format into a neutral protocol format and forwarding the application information in the neutral protocol format along with state information to other application router devices on the network.

Claims

1. A computer implemented method of routing application information, comprising:

receiving application information in a proprietary application protocol format over a network wherein the application information and the proprietary application protocol are associated with at least one application selected from a set of applications within an application network of applications that initially cannot exchange and use application data with each other;

converting the application information in the proprietary application protocol format into a neutral protocol format compatible with one or more application router devices on the network utilizing meta-data also provided by the one or more application router devices describing one of structures, interfaces and proprietary application protocols used by the one application selected form the set of applications within the application network of applications; and

forwarding the converted application information in the neutral protocol format along with state information describing the status of processing the application information to one or more application router devices on the network wherein the state information keeps the application router devices from losing track of information and status of the processing of the application information as it moves between the application router devices;

converting further application information in the neutral protocol format back into the proprietary application protocol when communicating the further application information back to the at least one application selected from the set of applications within the application network thereby facilitating the exchange and use of application data between the set of applications.

2. The method of claim 1 wherein the proprietary application protocol format is compatible with one or more protocols selected from the set of SOAP, XML/HTTP, IIOP, RMI, SQL, EDI and SNMP.

3. The method of claim 1 wherein the neutral protocol format is compatible with XML.

4. The method of claim 1 wherein converting the application information further comprises:

referencing meta-data to identify application information in the proprietary application protocol format wherein the meta-data further describe the proprietary application protocol format and the underlying application providing the information; and

mapping the application information to one or more structures in the neutral protocol format according to the meta-data.

5. The method of claim 1 wherein the meta-data used to identify application information is stored in a hierarchical data structure format.

6. The method of claim 1 wherein forwarding the state information further comprises:

determining if the processing of the application information has been completed based on the state information; and

transmitting status of the processing to one or more application routers indicating failure or success in processing of the application information based on the determination.

7. The method of claim 1 wherein the forwarding further comprises:

identifying application router devices in a virtual application area network (VAAN) as candidates for receiving application information in the neutral protocol format; and

limiting the transmission of application information in the neutral protocol format to router devices in the VAAN.

8. The method of claim 1 wherein the forwarding further comprises:

directing application information to a standby application router to act as a backup in the event an active application router device fails to operate properly.

9. A system for integrating the processing of applications, comprising:

an application network of applications that initially cannot exchange and use application data with each other having at least one application router having a processor and memory with instructions executable for providing meta-data to one or more other application router devices describing one of structures, interfaces and proprietary application protocols used by the one application selected form the set of applications within the application network of applications capable of communicating information about one or more applications with other application routers in a neutral protocol format once application data is converted from the proprietary application protocols; and

an application associated with the at least one application router that communicates in a proprietary application protocol and is converted by the at least one application router into the neutral protocol format utilizing meta-data provided by one or more application router devices describing one of structures, interfaces and proprietary application protocols used by an application selected form the set of applications within the application network of applications.

10. The system of claim 9 further comprising:

a standby application router that takes over communicating information from the at least one application router when the at least one application router experiences a temporary or permanent failure.

11. The system of claim 9 further comprising:

a virtual application area network within the application network that provides secure communication between the at least one application router and only selected application routers on the application network.

12. The system of claim 9 further including:

an application router configured to provide a dynamic application communication protocol to the at least one application router wherein the dynamic application communication protocol automatically assigns a registered application an application identifier for identifying the application in the application network.

13. An application router that routes application information, comprising:

a processor operable to execute instructions;

memory containing instructions when executed on the processor cause the application router to receive application information in a proprietary application protocol format over a network wherein the application information and the proprietary application protocol are associated with at least one application selected from a set of applications within an application network of applications that initially cannot exchange and use application data with each other, convert the application information in the proprietary application protocol format into a neutral protocol format compatible with one or more application router devices on the network utilizing meta-data also provided by the one or more application router devices describing one of structures, interfaces and proprietary application protocols used by the one application selected form the set of applications within the application network of applications, forward the converted application information in the neutral protocol format along with state information describing the status of processing the application information to one or more application router devices on the network wherein the state information keeps the application router devices from losing track of information and status of the processing of the application information as it moves between the application router devices and converting further application information in the neutral protocol format back into the proprietary application protocol when communicating the further application information back to the at least one application selected from the set of applications within the application network thereby facilitating the exchange and use of application data between the set of applications.

14. The application router of claim 13 wherein the neutral protocol format is compatible with XML.

15. The application router of claim 13 wherein converting the application information further comprises instructions when executed:

reference meta-data to identify application information in the proprietary application protocol format wherein the meta-data further describe the proprietary application protocol format and the underlying application providing the information and map the application information to one or more structures in the neutral protocol format according to the meta-data.
