Abstract
A congestion control method includes determining whether congestion occurs by monitoring a network, receiving an interest packet including a name of content data that is requested to be sent, generating a first NACK packet indicating an occurrence of congestion if it is determined that the congestion occurs when the interest packet is received, and sending the generated first NACK packet to the network. In the generating of the first NACK packet, if first alternative content data which is an alternative of the content data corresponding to a name included in the received interest packet is stored in a cache of the router, information regarding the first alternative content data is set in the first NACK packet. At least one of the determining whether the congestion occurs, the receiving the interest packet, the generating the NACK packet, and the sending the NACK packet is performed by a processor of the router.
