Abstract

In an embodiment, a data processing system comprises application workflow optimizing logic and which when executed is operable to receive first workflow data that defines a sequence of processing operations to perform on an application-layer message; rewrite the first workflow data by separation of dependent update operations to result in creating rewritten workflow data; and store the rewritten workflow data in a data repository. Application gateway logic may be operable to receive one or more packets; construct a received message from one or more payloads of the packets; classify the received message to identify a particular workflow associated with the message; apply the particular workflow, using the rewritten workflow data, to the received message to result in identifying a destination application server and creating an outgoing message; send the outgoing message to the destination application server.

Claims28

Dependent claims

A data processing system, comprising:

one or more hardware processors;
application workflow optimizing logic which when executed by the one or more hardware processors is operable to:
receive first workflow data that defines a sequence of processing operations to perform such operations on an application-layer message;
wherein the sequence of processing operations form a path defined by the first workflow data and the path includes one or more processing operations that change the content of the application-layer message and one or more processing operations that do not change the content of the application-layer message;
select, from the sequence of processing operations defined by the first workflow, one or more processing operations that do not change the content of the application-layer message;
rewrite the first workflow data to generate functionally equivalent rewritten workflow data by moving the selected one or more processing operations from the path defined by said first workflow data to a parallel path;
wherein moving the selected one or more processing operations removes the selected one or more processing operations from the path defined by the first workflow data and links remaining processing operations of the sequence of processing operations that form the path;
store the rewritten workflow data in a data repository.

5 more elements

A non-transitory machine-readable storage medium carrying one or more sequences of instructions, which instructions, when executed by one or more processors, cause the one or more processors to perform:

receiving first workflow data that defines a sequence of processing operations to perform such operations on an application-layer message;
wherein the sequence of processing operations form a path defined by the first workflow data and the path includes one or more processing operations that change the content of the application-layer message and one or more processing operations that do not change the content of the application-layer message;
selecting, from the sequence of processing operations defined by the first workflow, one or more processing operations that do not change the content of the application-layer message;
rewriting the first workflow data to generate functionally equivalent rewritten workflow data by moving the selected one or more processing operations from the path defined by said first workflow data to a parallel path;
wherein moving the selected one or more processing operations removes the selected one or more processing operations from the path defined by the first workflow data and links remaining processing operations of the sequence of processing operations that form the path;
storing the rewritten workflow data in a data repository.

3 more elements

A machine-implemented method, comprising:

receiving first workflow data that defines a sequence of processing operations to perform such operations on an application-layer message;
wherein the sequence of processing operations form a path defined by the first workflow data and the path includes one or more processing operations that change the content of the application-layer message and one or more processing operations that do not change the content of the application-layer message;
selecting, from the sequence of processing operations defined by the first workflow, one or more processing operations that do not change the content of the application-layer message;
rewriting the first workflow data to generate functionally equivalent rewritten workflow data by moving the selected one or more processing operations from the path defined by said first workflow data to a parallel path;
wherein moving the selected one or more processing operations removes the selected one or more processing operations from the path defined by the first workflow data and links remaining processing operations of the sequence of processing operations that form the path;
storing the rewritten workflow data in a data repository;
the method performed by one or more computing devices.
