Two independent pointers within a message descriptor are used to link the message descriptor to various queues during transmission of a message from a sender node to a receiver node within a computer environment. In particular, one pointer is used to link the message descriptor on either a pending send queue or a send queue, while the other pointer is used to link the message descriptor on either an unacknowledged queue or an acknowledged queue. For example, when a message is sent, it is removed from the send queue using one pointer and placed on the unacknowledged queue using the other pointer. Further, if the message is resent, it is linked back onto the send queue using the send queue pointer without disturbing the order of the message on the unacknowledged queue. Thus, ordering of message transmission is preserved, even when a message is sent multiple times.
