Abstract

The disclosed embodiments relate to implementation, such as by a message processing system architecture, of a message handling system and/or protocol which mitigates optimistic messaging behavior. As used herein optimistic messaging behavior may at least refer to the transmission, in whole or in part, of a message, or of one or more messages of a sequence thereof, to a receiving system, such as the system implemented by the disclosed embodiments, prior to the sender determining that the message(s) is/are desired, alone or in conjunction with subsequently canceling or otherwise invalidating the message(s) once it has been determined that it is not desired. The disclosed embodiments mitigate such behavior by detecting and taking action with respect to these types of messages to deter optimizing behavior which may or may not be manipulative, while maintaining reliable message handling under increasing processing loads with minimal impact on users being able to send messages to the system.

Claims20

Dependent claims

A system for processing a data message received via a network from a source, the data message comprising a portion that is generated by the source dependent upon an event and a portion that is generated by the source independent of the event, the system comprising:

a memory storing computer executable instructions executable by one or more processors to cause the one or more processors to implement:
a message receiver coupled with the network and operative to:
receive multiple packets compliant with an asynchronous packet transport protocol, the data message being transported over the network via the multiple packets;
and
reconstruct the data message from the multiple packets using the asynchronous packet transport protocol;
a message analyzer coupled with the message receiver and operative to automatically analyze the data message to determine, based on packet timing information captured for compliance with the asynchronous packet transport protocol and without knowledge of when the source became aware of the event, if the event independent portion was transmitted by the source prior to occurrence of the event by evaluating whether all of the event independent portion was received prior to any of the event dependent portion;
a message processor coupled with the message analyzer and operative to:
when it is determined that the event independent portion was transmitted by the source prior to occurrence of the event, disconnect a connection via the network for the source of the data message;
and
when it is determined that none of the event independent portion was transmitted by the source prior to occurrence of the event, forward the data message to the destination application without disconnecting the connection.
