Abstract

Application level switching of transactions at a gateway is provided. The gateway is configured to switch the transaction based on the application level content, a current state of a transport environment, and/or dynamic rules for switching transactions. For example, several possible service providers can be selected for the type of transaction, and the gateway can monitor not only the round-trip time through the network(s) to different possible service providers, but also the time required to complete the transaction at the application level and return a response. The application is chosen on the sending side of the network, and application level formatting is done on the sending side as well. The gateway uses modular code and data, and separate instances of processing code to allow dynamic updating. Rules for application service selection can be selectively uploaded to the gateway from a client. The rules for different available application services can be distributed across different gateways.

Claims

1. A method comprising:

receiving a transaction in a first format from a merchant point of sale device at a gateway;

determining application level information for the transaction, wherein the application level information comprises information used in processing the transaction;

determining a rule based on the application level information, wherein determining the rule comprises determining the merchant point of sale device from the application level information and determining merchant point of sale device-specific rules for processing the transaction in a database or based on one or more merchant point of sale device subscriptions to services provided by a service provider, and wherein the merchant point of sale device-specific rules include one or more dynamic and static conditions for switching the transaction across a plurality of networks, wherein different service providers are accessible through the plurality of networks;

applying the rule to the application level information;

determining a service for the transaction based on the application of the rule to the application level information, wherein rules for the different service providers are stored at the gateway;

based on a set of service provider rules associated with the service provider for the determined service;

translating the transaction from the first format into a second format specified by the service provider for the determined service, and

processing the transaction in the second format; and

sending the processed transaction to the merchant point of sale device.

2. The method of claim 1 wherein processing the transaction in the second format further comprises sending the transaction in the second format to the service provider.

3. The method of claim 2 wherein the service provider is a transaction processor connected to the gateway via one of the plurality of networks.

4. The method of claim 3 wherein the transaction processer is a financial transaction service provider.

5. The method of claim 1 wherein the second format is a canonical format that can be processed by the service provider for the determined service.

6. The method of claim 1 wherein the database includes rules for determining the service for the transaction, and a network from the plurality of networks and the service provider to process the transaction.

7. The method of claim 1 wherein the database includes the set of service provider rules specifying a message format required for the transaction.

8. The method of claim 1 wherein the merchant point of sale device-specific rules are sent immediately before or after the transaction is sent and dynamically loaded onto the gateway to configure the gateway at run-time.

9. The method of claim 1 wherein the service provider rules specify that transactions with values below a threshold value can be processed and approved by the gateway without switching the transaction over one of the plurality of networks to the server provider.

10. The method of claim 1 wherein processing the transaction in the second format further comprises processing the transaction, at the gateway, based on the service provider rules for the determined service.

11. The method of claim 1 wherein the rules for the different service providers are distributed to the gateway by the different service providers.

12. A gateway comprising:

a request handler connected to a merchant point of sale device to receive a transaction comprising application level information from the merchant point of sale device in a first format, wherein the application level information comprises information used by a service provider in processing the transaction;

an adaptive route handler connected to a message stream parser to determine application level data from the transaction in a second format;

a rules database connected to the adaptive route handler;

wherein the adaptive route handler accesses the rules database to determine rules specified by the merchant point of sale device for processing the transaction and to determine a service for the transaction based on an application of the determined rules to the application level information, wherein rules for different service providers are stored at the gateway, and further to route the transaction to a service provider that can provide the determined service, and wherein the rules specified by the merchant point of sale device for processing the transaction include one or more dynamic and static conditions for switching the transaction across a plurality of networks, wherein the different service providers are accessible through the plurality of networks;

the message stream parser connected to the request handler to convert the transaction in the first format to the second format specified by the service provider that can provide the determined service; and

a flow handler connected to the adaptive route handler to send the transaction in the second format to the service provider.

13. The gateway of claim 12 wherein the second format is a canonical format that can be processed by the service provider.

14. The gateway of claim 13 further comprising a plurality of software applications wherein at least one functions as the service provider.

15. The gateway of claim 14 wherein each of the plurality of software applications is provided by one or more transaction processors and can process the transaction in the canonical format.

16. The gateway of claim 12 wherein the second format is specific to the service provider.

17. The gateway of claim 16 wherein the service provider is a transaction processor.

18. The gateway of claim 17 wherein the service provider is connected to the gateway via a network and is selected from the group consisting of issuers, acquirers, merchants, and transaction processors.
