<p><P>PROBLEM TO BE SOLVED: To provide a communication frame distribution system capable of efficiently transmitting/receiving a plurality of downstream data items (communication frames) over a multihop tree type network. <P>SOLUTION: In a communication frame distribution system, a packet generating device stores connection relations of communication terminates constituting a network, a data size of each frame to be transmitted and a maximum data size containable in one packet and aggregates a plurality of frames based therein as at least one aggregation data item. Furthermore, the packet generating device generates a packet for each aggregation data item, determines a destination of the packet based on a destination of a frame contained in the packet and the connection relations of the communication terminals and transmits the packet. Moreover, a communication terminal device determines that, only in a case where a communication frame destined to a communication terminal device connected to the downstream of itself is contained in a received packet, the relevant packet is to be relayed, and transmits the relevant packet toward the destination thereof. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
