Definitions
- the invention relates to managing the propagation of messages in an asynchronous system.
- Effective asynchronous communication between message providers and consumer objects generally requires an intermediary object that decouples the communication.
- Such an intermediary object has the capacity for storing and transferring messages. It is called asynchronous broker
- the invention consists of a method of asynchronous communication of messages between an ob
- and consumer of messages defines a set rules regarding the throughput of messages received and specifies it to the asynchronous broker. This definition can be fixed, or redefined dynamically during the various communications For example one can redefine the rules periodically
- the rules can consist in defining a maximum threshold of messages.
- the asynchronous broker transmits the information concerning the flow of messages to the consumer.
- the invention places control at the level of the asynchronous broker, who from this point of view stinks of the role of a scheduler
- the scheduler must then watch over the application of the time scheduling constraints provided to it by the consumer.
- a consumer specifies with the scheduler the scheduling rules which fix the debit he wishes to accept.
- the consumer adjusts the traffic by requesting a change in the scheduling rules.
- the scheduler may have to retrieve messages directly from the producers.
- the scheduler orders the broker to memorize the messages on behalf of the registered consumer.
- the main task of the scheduler is to apply the scheduling rules provided by the consumer, his second task is to measure the state of traffic and provide the corresponding information.
- the invention is particularly suited to the transactional context.
- the acceptance of messages in the broker is subject to validation of the transaction which produced them.
- each decision taken by the latter to transmit messages to the consumer is made consistent with the messages from the suppliers.
- the decisions made by the scheduler are stored in a secure memory as part of the supplier's transaction. Thus, if the transaction fails, the decision is canceled.
- the invention makes it possible to guarantee the fluidity of the transmission of messages between suppliers and consumers. As a result, the consumer does not experience sudden changes in traffic. The consumer no longer takes care of the flow control and receives precise information on the traffic allowing him to adjust his rate of reception of the messages.
- the conventional solution is contained in the invention. It is possible to suspend reception by defining a zero flow and to resume it by modifying said flow.
