METHOD AND A DEVICE FOR CONTROLLING A REAL-TIME SPEED OF A DATA TRANSMISSION NETWORK, SPECIALLY CORRELATED TO PERCEIVING A DOWNLOAD SPEED OF A CHILD NODE AND AN UPLOAD SPEED OF A PARENT NODE IN REAL TIME

摘要

PURPOSE: A method and a device for controlling a real-time speed of a data transmission network are provided to enable a child client to transmit maximum speed, requested speed, and current speed data to a parent client, so that the parent client can transmit calculated maximum speed, requested speed, and current speed data to the child client, thereby buffering continuous data by controlling each node speed. CONSTITUTION: A server assigns a parent client to a child client at the request of the child client. If a data block is transmitted to the child client at more than a requested speed of the child client, the parent client converts an amount of excessive data into a time to delay the data as much as the corresponding time, and transmits a next data block to the child client. The child client transmits maximum speed, requested speed, and current speed data to the parent client, so that the parent client can send calculated maximum speed, requested speed, and current speed data to the child client.
