<P>PROBLEM TO BE SOLVED: To enable a plurality of communication apparatuses which are not synchronized to communicate in a time division manner in a wired network. <P>SOLUTION: The repeating device comprises: a collision detection section which, while receiving a first data packet group or a first control packet group in a first transmission source IF from a first communication apparatus, is used for reserving transmission, from a second communication apparatus, of a second data packet group in a certain period at one-frame beyond the current frame within frame sequences indicating a operation period in the second communication apparatus in a second transmission source IF, and detects a collision of receiving a second control packet group where a transmission destination IF coincides with a transmission destination IF of the first data packet group or the first control packet group; and a collision occurrence notification section which transmits, to the second communication apparatus, in the case where the collision is detected, a collision occurrence notification including an adjustment time not less than the time from reception start of the first packet of the second control packet group to reception end of the last packet of the first data packet group or the first control packet group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
