<p>Disclosed is an estimation apparatus or the like that is capable of highly accurately estimating a communication network state, such as communication delay. An estimation apparatus (1504) has an estimation unit (1507) that estimates, on the basis of fourth timing (1505) at which a packet is transmitted, and fifth timing (1506) at which a packet corresponding to the packet is received, a second timing at which a communication resource is to be allocated, or third timing at which the allocated communication resource is to be deallocated, or a second period when the communication resource is to be allocated, in a communication network.</p> |
