Upon receiving, from a first other communication apparatus, a first acquisition request of requesting apparatus information relating to another communication apparatus that exists in a cluster, a communication apparatus transmits a second acquisition request that corresponds to the first acquisition request to a second other communication apparatus that exists in a cluster, determines a waiting time for awaiting a response to the second acquisition request from the second other communication apparatus, receives the apparatus information from the second other communication apparatus during the waiting time, and transmits the apparatus information received during the waiting time collectively to the first other communication apparatus. |
