Date Mar. 21, 1996A flow control method is practiced in a first node in a computer network having one or more upstream nodes, each of which can provide data cells to the first node over a connection. Cells are transmitted over a connection during an established transmission period for that connection and at a data rate not exceeding a peak data rate. To determine whether a buffer is sufficient during a given time period starting at the current time, the potential buffer requirements during that time period are established as a function of the current buffer occupancy and the maximum number of cells which may be received during the given time period. If the potential buffer requirements exceed a predetermined buffer threshold, one or more stop signals is sent to upstream sources to limit the number of cells to be provided to the first node.
