Communication connecting device adaptive to an IP network and communication rate control method therefor

摘要

A communication connecting device (10) includes a data storage (14) to which data read by a scanner are written. A packetizer (16) packetizes the data read out of the data storage (14) in accordance with a packet size fed from a size information storage (18). A rate controller (20) counts a period of time after the start of packet transmission or a period of time consumed to send a preselected number of packets. The rate controller (20) calculates a communication rate on the basis of the above period of time and the number of packets sent, and then compares the communication rate with a communication rate assigned to a receiving terminal and defined by a Recommendation T.30 protocol. The rate controller (20) allows the packets to be sent only if the calculated communication rate is lower than the communication rate of the receiving terminal.
