Abstract

Methods, apparatus, and products are disclosed for dispatching a message request to a service provider in a messaging environment that include: establishing, on a message administration device, a plurality of lookup tables for mapping request types to service providers; receiving, in the message administration device from a message requesting device, a message request of one of the request types; identifying, by the message administration device, the service provider for processing the message request in dependence upon the message request and the plurality of lookup tables; and providing, by the message administration device, the message request to the identified service provider.

receiving, in the message administration device from a message requesting device, a message request of one of the request types;

identifying, by the message administration device, the service provider for processing the message request in dependence upon the message request and the plurality of lookup tables; and

providing, by the message administration device, the message request to the identified service provider.

2. The method of claim 1 wherein establishing, on a message administration device, a plurality of lookup tables for mapping a request type to a service provider further comprises:

retrieving, from a configuration policy, the plurality of request parameters specified in the message requests of the request types;

retrieving, from the configuration policy, the parameter value for each request parameter specifying each request type;

retrieving, from the configuration policy, service provider identifiers of the service providers for processing the message requests of each of the request types; and

creating the plurality of lookup tables in dependence upon the retrieved request parameters, the retrieved parameter values, and the retrieved service provider identifiers.

3. The method of claim 1 wherein identifying, by the message administration device, the service provider for processing the message request in dependence upon the message request and the plurality of lookup tables further comprises repeatedly identifying the entry in one of the plurality of lookup tables specifying a logical connection among the plurality of lookup tables in dependence upon the message request and traversing the logical connection specified by the entry to another lookup table in the plurality of lookup tables until identifying the entry in one of the plurality of lookup tables specifying the service provider in dependence upon the message request.

4. The method of claim 1 wherein providing, by the message administration device, the received message request to the identified service provider further comprises calling a function of the service provider using the parameter value for each request parameter specified in the message request.

5. The method of claim 1 further comprising:

determining whether the message requesting device is authorized to have the message request processed by the service provider,

wherein providing, by the message administration device, the received message request to the identified service provider further comprises providing, by the message administration device, the received message request to the identified service provider if the message requesting device is authorized to have the message request processed by the service provider.

6. The method of claim 1 wherein the message request is a request to establish a message stream with a feed adapter, the method further comprising:

receiving, by the message administration device in response to providing the received message request to the identified service provider, a data communications endpoint of the message stream from the feed adapter; and

providing, by the message administration device, the data communications endpoint to the message requesting device.

7. The method of claim 1 wherein the parameter value for at least one of the request parameters is a default value.

8. The method of claim 1 wherein the messaging environment is a financial market data messaging environment.

9. An apparatus for dispatching a message request to a service provider in a messaging environment, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:

establishing, on a message administration device, a plurality of lookup tables for mapping request types to service providers, the service providers capable of processing message requests of each of the request types, the message requests of the request types specifying a plurality of request parameters, each request type specified by a parameter value for each request parameter, each lookup table corresponding to one of the request parameters, each lookup table including entries for parameter values of the request parameter corresponding to the lookup table, the entries included in the plurality of lookup tables corresponding to one of the request parameters specify the service providers, and the entries included in the plurality of lookup tables corresponding to the other request parameters specify logical connections among the plurality of lookup tables;

receiving, in the message administration device from a message requesting device, a message request of one of the request types;

identifying, by the message administration device, the service provider for processing the message request in dependence upon the message request and the plurality of lookup tables; and

providing, by the message administration device, the message request to the identified service provider.

10. The apparatus of claim 9 wherein establishing, on a message administration device, a plurality of lookup tables for mapping a request type to a service provider further comprises:

retrieving, from a configuration policy, the plurality of request parameters specified in the message requests of the request types;

retrieving, from the configuration policy, the parameter value for each request parameter specifying each request type;

retrieving, from the configuration policy, service provider identifiers of the service providers for processing the message requests of each of the request types; and

creating the plurality of lookup tables in dependence upon the retrieved request parameters, the retrieved parameter values, and the retrieved service provider identifiers.

11. The apparatus of claim 9 further comprising computer program instructions capable of:

determining whether the message requesting device is authorized to have the message request processed by the service provider,

wherein providing, by the message administration device, the received message request to the identified service provider further comprises providing, by the message administration device, the received message request to the identified service provider if the message requesting device is authorized to have the message request processed by the service provider.

12. The apparatus of claim 9 wherein the message request is a request to establish a message stream with a feed adapter, the apparatus further comprising computer program instructions capable of:

receiving, by the message administration device in response to providing the received message request to the identified service provider, a data communications endpoint of the message stream from the feed adapter; and
