A method for determining whether a transaction correctly has elapsed, a network node and a data transmission network for carrying out the method

摘要

This invention relates to a method for determining whether a transaction comprising a transmission of content data from a first subscriber to a second subscriber via network nodes of a data transmission network building a transmission path, said transmission network being controlled by controlling means of a network controller, is completed correctly and a data transmission network and a network node comprising means, being designed to carry out the method. The method is comprising the steps of receiving said content data from said first subscriber by a first network node of said network nodes, setting up a first data content report, comprising information about said content data, or receiving said first data content report from said first subscriber, by said first network node, setting up said transmission path by choosing a second network node of said network nodes, having an exclusive data transfer connection to said second subscriber, by said network controlling means, sending said content data from said first network node to said second network node, setting up a second data content report, comprising information about said content data, by said second network node, sending said content data from said second network node to said second subscriber, making a comparison by comparing said first data content report to said second data content report, by said network controlling means and deciding whether said transmission of content data from said first subscriber to said second subscriber is completed correctly depending on a result of said comparison, by said network controlling means.
