Abstract
An object of the present invention is to provide a technology capable of estimating header conversion applied in a network by collecting information required in the estimation, without introducing a special-purpose server directed to estimate header conversion applied in the network. The present invention provides a system for estimating information about apparatuses on a network using an error message or control message sent in response to a transmitted packet as stipulated by a communication protocol to estimate information about apparatuses on the network.
