Abstract: An object is to provide a communication apparatus, a communication method, and a program capable of avoiding an increase in network load when input traffic continues to be large and a communication delay when input traffic is very small. A communication apparatus according to the present invention prepares three token buckets and can transfer, discard, or hold a packet in accordance with the amount of tokens in each token bucket. This enables the communication apparatus to operate so as not to exceed a set maximum bandwidth when large traffic is received for the delay guarantee shaping. Further, When the maximum bandwidth is exceeded, the communication apparatus can select whether to discard a packet to prioritize a delay guarantee or to hold a packet to prioritize no loss of packets. Furthermore, the communication apparatus can immediately transmit a packet without increasing a communication delay when input traffic is very small.
