NETWORK SYSTEM AND COMMUNICATION BAND CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To make dynamic band control possible on the basis of band information generated in the subnet.

SOLUTION: In the network system wherein a plurality of nodes being operated by their communication application programs 27 are connected to a network 1, each node 2 includes a transmission rate control module 25 for obtaining a communication attribute required for controlling a communication band from the communication application program 27, a band information managing table 26 for storing the obtained communication attribute, a band information transmission module 24 for delivering the band information of the local node to all the other nodes connected with the network, and a band information receiving module 23 for receiving the band information delivered by the band information transmitting module 24 of another node and storing the band information in the band information managing table 26. The transmission rate control module 25 is served to obtain the current band traffic on the basis of the band information stored in the band information managing table 26 and perform the band control.
