摘要： A transmission device includes: a first counter; a counter control unit configured to increment the first counter at a specified rate; a frame buffer configured to store a received frame; and a buffer control unit configured to read a frame from the frame buffer when a value of the first counter is larger than a specified threshold and output the frame. When a length of an output frame read from the frame buffer by the buffer control unit is shorter than a specified reference frame length, the counter control unit decrements the first counter by a value indicating the reference frame length. When the length of the output frame is longer than or equal to the reference frame length, the counter control unit decrements the first counter by a value indicating the length of the output frame.

摘要： A collision detection unit detects whether a first entry that is associated with a value obtained by hashing a first MAC address is present in each area in a MAC address table and detects whether a second entry that is associated with a value obtained by hashing a second MAC address is present in each area in the MAC address table. If the first entry is present in each of the areas, a collision avoidance control unit acquires the second MAC address stored in the first entry that is present in one of the areas and inputs the second MAC address in the collision detection unit. If the second entry is not present in any of the areas in the MAC address table, a registration unit stores the second MAC address in the second entry and stores the first MAC address in the first entry.
