ABSTRACT:
A network apparatus according to the present invention is connected to a single server apparatus or a plurality of server apparatus via a link. The network administrator sets in advance the band volume to be used by a frame transmitted from each of the server apparatus within the range of the communication band volume possessed by the link. The network apparatus has a band controller that instructs each of the server apparatus to transmit a PAUSE frame. The network apparatus is also provided with a transmitter that transmits a PAUSE frame to each of the server apparatus via the link according to the instruction of the band controller. Each of the server apparatus receives the PAUSE frame transmitted from the network apparatus. Each of the server apparatus suspends frame transmission to the network apparatus for the suspension period set in the received PAUSE frame.
