Method and system for measuring the travel time of roundtrip (RTT) in the communication of packets between ports of a communication network of packet switching.And to manage a communication network of packet switching, communication network of packet switching, and the product of computer program.A method and system for measuring the time related return travel time (RTT) in the communication of packets between ports of a communication network of packet switching, in which.Among other packages, packages of the report, such as package of RTCP the type of Mr.They are transmitted by the doors of transmission for doors of destination in response to the previous packets received from said respective ports of destination,Comprising the steps of: (a) detecting at any point of the network, and the packet traffic flowing through it.A first package report transmitted by a first port to a second port, and a second package report responsive to said first package report; (b) to compute the time perThe course of roundtrip between the said first and second ports as a function of the data transmission time of the packet of the report (NTP) and delayed (DLSR) provided in said second set of reportSion also presented a report and data transmission time of a prior report (LSR) and delayed (DLSR) provided in said first package report.
