A flow control method and system including an algorithm for deciding to transmit an arriving packet into a processing queue or to discard it, or, in the case of instructions or packets that must not be discarded, a similar method and system for deciding at a service event to transmit an instruction or packet into a processing queue or to skip the service event. The transmit probability is increased or decreased in consideration of minimum and maximum limits for each flow, aggregate limits for sets of flows, relative priority among flows, queue occupancy, and rate of change of queue occupancy. The effects include protection of flows below their minimum rates, correction of flows above their maximum rates, and, for flows between minimum and maximum rates, reduction of constituent flows of an aggregate that is above its aggregate maximum. Practice of the invention results in low queue occupancy during steady congestion.

The specification shows and describes a visual display of the CRT variety wherein column separator lines may be displayed intermediate character matrix positions as an operator aid. The visual column separators further do not require that any character position be used or encroached upon and where limited spacing occurs between character forming dot matrices, logic delays may be utilized in the video modify circuitry to displace the separator line and thereby visually distinguish such separator line from any adjoining character.
