Abstract:
In a scheduling apparatus, a packet start time with respect to an input packet is calculated, and a slot corresponding to the packet start time is selected from a scheduler including a plurality of slots. Whether to store the packet in the selected slot in consideration of the number of packets stored in the selected slot and the number of packets corresponding to virtual ports corresponding to the input packet is determined, and here, the virtual port is an output port of a switch device which is connected to the outside and does not have a scheduling function.
Abstract:
Provided are a packet switch system in which an input module and an output module measure a buffer state and a packet delivery rate to control traffic, regardless of a size or a function of a switch fabric, and a traffic control method thereof. The packet switch system includes an input unit including a plurality of input modules, an output unit including a plurality of output modules, and a switch fabric including a plurality of switch components and configured to receive a packet delivered from the input unit and deliver the received packet to the output unit, wherein each of the input module includes: a plurality of virtual output queues (VOQs); and an access controller configured to selectively output packets stored in the plurality of VOQs in a weighted round robin (WRR) manner.
