Abstract:
A method of managing a message transfer session between first and second nodes in a message queuing system, comprising the steps of:specifying by the first node to the second node a first acknowledgment timeout period for the second node to acknowledge receipt of packets sent by the first node and a first window size for message transfer from the second node to the first node;returning by the second node to the first node a second acknowledgment timeout period for the first node to acknowledge receipt of packets sent by the second node and a second window size for message transfer from the first node to the second node;transmitting from the first node to the second node multiple message packets up to the second window size;sending a session acknowledgment from the second node to the first node indicating whether the multiple message packets from the first node are received by the second node;wherein the session acknowledgment includes a window size field for specifying a new window size for message transfer to the second node to dynamically adjust a maximum number of message packets allowed to be transferred to the second node based on resources available to the second node.
