FIELD: electric communication. SUBSTANCE: method provides for usage of network controlling electric communication to select routing table through operating centers of existing network by means of universal interface of control over information. Then network controlling electric communication determines message tree between sending and designation centers chosen by operator and finds out by means of this tree number of sent, acknowledged and received messages which will be generated by conducting this routing test in network. Technical result of invention consists in the fact that operator will be informed on load that will be formed in network by this test before conducting above-mentioned test. That is why operator can conduct routing test at his discretion, being sure that conducting this test will not create overload conditions. EFFECT: improved conditions for conducting routing test. 17 cl, 7 dwg
