PACKET SWITCH SYSTEM AND TRAFFIC CONTROL METHOD THEREOF

摘要

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.
