Abstract: A technique called "Adaptive Pacing" permits a receiving node, in a computing networking, to change the size of an information window during an active session. To effect the change, the receiving node sends an "Isolated Pacing Message" (IPM) to the sending node. Thereafter, the sending node adjusts the window size to conform with a window size value in the IPM. The IPM includes a type field, a reset window indicator and a next window size field. There are three types of isolated pacing messages. Two of the messages are used by the receiving node to control the flow of data; while the third message is used, by the sending node, to confirm the beginning of a new window and the ending of an old one.
