Method for Extending Queue Capacity and Message Processing Device Capable of Extending Queue Capacity

摘要

A method for extending queue capacity and a message processing device capable of extending queue capacity are provided to utilize a number of queues by relating the queue directory of the queue and the logic address information of the message. A method for extending queue capacity includes the steps of: transmitting a received message to a writer; determining if the queue count value coincides with the maximum queue count value after checking the count information of the queue(504); creating a second queue at a memory when the count value of the queue coincides with the maximum queue count value(508); and storing the provided message from a listener to the directory of the second queue(506,510). The first directory of the created second queue should be connected with the last directory of the first queue.
