Abstract

Techniques are provided for intelligent routing to a node in a network, such as a transport computer. A gateway server may receive authorization requests from a resource provider computer. There may be multiple potential transport computers to which to potentially route the authorization requests, depending on relationships established between the parties. A routing decision may be made automatically based on real-time network measurements and/or static rules. Real-time network measurements may be obtained by monitoring transport computers for failures, delays, or other undesirable activity. The routing decisions may further be based on expected volumes (e.g., based on analysis of historical spikes in volume). The routing decisions may further be based on user-configured rules and preferences, received via a routing administration interface.

First claim

What is claimed is:

1. A method comprising performing, by a gateway server:
receiving, from a resource provider computer, an authorization request for accessing a resource, the authorization request comprising a resource provider identifier corresponding to a resource provider;
determining, based on the resource provider identifier, a set of transport computers;
for each transport computer of the set of transport computers:
retrieving, from the transport computer, status information of the transport computer;
determining a measure of network availability of the transport computer over a network based on the status information retrieved from the transport computer; and
identifying an expected volume of authorization requests for the transport computer, wherein identifying the expected volume of authorization requests for each transport computer, of the set of transport computers, comprises computing a volume of authorization requests recently received by the transport computer;

retrieving, from a database, a stored plurality of rules for transport computer selection;
based at least upon the stored plurality of rules, the expected volume of authorization requests for each transport computer, of the set of transport computers, and the measure of network availability of each transport computer, of the set of transport computers:
selecting a particular transport computer for processing the authorization request; and
transmitting, over the network, the authorization request to the particular transport computer, wherein the authorization request for accessing the resource is thereafter approved or declined.

2. The method of claim 1 , wherein identifying the expected volume of authorization requests for the transport computer comprises:
retrieving a plurality of parameters associated with a set of authorization requests previously received by the transport computer;
identifying a corresponding plurality of current data elements associated with the transport computer; and
comparing the corresponding plurality of current data elements associated with the transport computer to the plurality of parameters associated with the set of authorization requests previously received by the transport computer.

3. The method of claim 1 , wherein the status information retrieved from the transport computer comprises one or more of: an error code, a response code, or a response time.

4. The method of claim 1 , wherein:
retrieving the status information of the transport computer comprises:
transmitting one or more messages to the transport computer; and
recording one or more respective response times or connection failures; and

determining the measure of network availability of the transport computer comprises computing a score based on the one or more respective response times or connection failures.

5. The method of claim 1 , wherein determining the measure of network availability of the transport computer comprises:
receiving a number of heartbeat messages from the transport computer over a time period; and
determining the measure of network availability of the transport computer comprises comparing the number of heartbeat messages received over the time period to an expected number of heartbeat messages to be received over that time period, the expected number of heartbeat messages determined based on a specified heartbeat message rate and a length of the time period.

6. The method of claim 1 , further comprising:
transmitting a plurality of requests to the transport computer;
receiving a respective plurality of responses from the transport computer, each response indicating either a success or a decline;
based on the respective plurality of responses, computing a ratio of declines to successes; and
comparing the computed ratio to a baseline ratio,
wherein the particular transport computer is selected based on the comparison.

7. The method of claim 1 , further comprising:
computing a score based on the measure of network availability, the expected volume of authorization requests, and the stored plurality of rules; and
using the score in selecting the particular transport computer.

8. The method of claim 1 , further comprising, before retrieving the stored plurality of rules:
causing display of an interface for the resource provider to configure rules;
receiving, by the gateway server via the interface, input to configure a rule;
based on the input, generating the rule; and
storing the rule, as part of the stored plurality of rules.

9. The method of claim 1 , further comprising:
receiving a notification that the particular transport computer has failed to process the authorization request;
based at least upon the notification, the stored plurality of rules, the expected volume of authorization requests for each transport computer, of the set of transport computers, and the measure of network availability of each transport computer, of the set of transport computers:
selecting a different transport computer for processing the authorization request; and
transmitting the authorization request to the different transport computer.

10. A gateway server comprising:
a processor; and
a non-transitory computer-readable medium coupled to the processor, the non-transitory computer-readable medium comprising code executable by the processor to perform a method comprising:
receiving, from a resource provider computer, an authorization request for accessing a resource, the authorization request comprising a resource provider identifier corresponding to a resource provider;
determining, based on the resource provider identifier, a set of transport computers;
for each transport computer of the set of transport computers:
retrieving, from the transport computer, status information of the transport computer;
determining a measure of network availability of the transport computer over a network based on the status information retrieved from the transport computer; and
identifying an expected volume of authorization requests for the transport computer, wherein identifying the expected volume of authorization requests for each transport computer, of the set of transport computers, comprises computing a volume of authorization requests recently received by the transport computer;

retrieving, from a database, a stored plurality of rules for transport computer selection;
based at least upon the stored plurality of rules, the expected volume of authorization requests for each transport computer, of the set of transport computers, and the measure of network availability of each transport computer, of the set of transport computers:
selecting a particular transport computer for processing the authorization request; and
transmitting, over the network, the authorization request to the particular transport computer, wherein the authorization request for accessing the resource is thereafter approved or declined.

11. The gateway server of claim 10 , wherein identifying the expected volume of authorization requests for the transport computer comprises:
retrieving a plurality of parameters associated with a set of authorization requests previously received by the transport computer;
identifying a corresponding plurality of current data elements associated with the transport computer; and
comparing the corresponding plurality of current data elements associated with the transport computer to the plurality of parameters associated with the set of authorization requests previously received by the transport computer.

12. The gateway server of claim 10 , wherein the status information retrieved from the transport computer comprises one or more of: an error
