  • Communication apparatus and method
    Patent number: 9450851
    Abstract: In a communication apparatus, based on the relationship among a first port for outputting frames including tag information, a frame destination address, and bandwidth specified to the first port, a controller generates threshold value information to be associated with a second port to which the frames including tag information are input. With respect to the frames input from the second port, a reception processor measures a reception rate according to the tag information and the frame destination address, and selects, based on the reception rate and the threshold value information, frames to be preferentially discarded at the first port.
