Controlled-feedback packet switching system.
Abstract
Packets or cells received from different input ports (101₁, 101n) of a switch (102) and destined for a common output port (103₁ - 103n) of that switch, are analyzed to determine their priority level. Lower-priority packets or cells are buffered in recirculation delay lines (105₁ - 105m) of appropriately-selected lengths, and thereafter scheduled for transmission to the output port based on their level of priority.
