1. A network control apparatus controlling, in an ad-hoc network structured with a terminal apparatus, a relay apparatus, and a gateway apparatus connected to each other through data links, the ad-hoc network through which data is transferred from the terminal apparatus to the gateway apparatus via the relay apparatus,wherein routing in the ad-hoc network is established using routing information including information regarding a transmission error rate at each of the data links, andsaid network control apparatus comprises:

  • a routing processing unit configured to obtain, from the routing information, information regarding a relationship between data links in connecting relay apparatuses on a path and information regarding the transmission error rate at each of the data links; and

    a bottleneck estimating unit configured to estimate a relay apparatus as a bottleneck candidate from among the relay apparatuses, the relay apparatus having a data link through which the data is transmitted and at which the transmission error rate is higher than the transmission error rate at a data link through which the data is received.
