摘要：Provided is a communication device and method that is capable of utilizing ECN functions effectively. The communication device includes: a first communication unit 11; a second communication unit 12; a first determination unit 13 that determines whether a PC 101 to which the first communication unit 11 is connected and a PC 301 on a network 202 side communicating with the second communication unit 12 have a congestion control function against data congestion; a second determination unit 14 that determines whether data congestion is occurring in the PC 301; and a control unit 15 that adds first control data for activating the congestion control function provided in the PC 101 to data to be transmitted to the PC 101, and that causes the first communication unit 11 to transmit the data, in a case in which it is determined that the device to which the first communication unit 11 is connected has the congestion control function, but the PC 301 communicating with the second communication unit 12 does not have the congestion control function, and it is determined that data congestion is occurring in the PC 301.
