Packet flow control apparatuses and methods for controlling the same

摘要

A packet flow control apparatus performing flow control of packets each having variable length, includes: a buffer memory (1) for temporarily accumulating arrived packets until a sending time of each packet; a counter updated based on a rate determined in accordance with a packet length calculated by a counter value of the counter and limited flow of packets; a sending time determining section (2) for determining the sending time of each packet based on the counter value and a present time; and a sending order control section (3) for managing a sending order of each packet accumulated in the buffer memory, and for sending a read instruction of each packet to the buffer memory, based on the sending time determined by the sending time determining section. <IMAGE>
