TCP response message, corresponding Message Processing or time delays processing can be executed to the TCP response message, so that it is backward
Server forwarding TCP response message after treatment, allow measuring device monitor in real time client and server it
Between data transmission scenarios on network.
S202, preset delay time reach when, to server end send TCP response message.
Wherein, delay time can be customized according to practical application request by user, for indicating that measuring device delay turns
Send out the time of TCP response message.
Based on the above embodiment, it is to be understood that the present embodiment describes measuring device and receives to from client
The TCP response message arrived carries out the process of delay process, i.e. measuring device presets a delay time, then sets in measurement
After the standby TCP response message for receiving client transmission, needs to wait delay time and then send TCP response to server
Message, to guarantee that server can normally receive the TCP response message of client transmission.It should be noted that above-mentioned prolongs
The slow time can be the time of a variation, and initial value can be set as 0, also can be set as other values, which can
Periodically to carry out value-added variation, the present embodiment is not limited this.
The above-mentioned client of exemplary illustration and server carry out the detailed process of interacting message, as shown in Figure 3A, in the number
According in transmission process, server sends the TCP message (D1, D 2, D 3, D4, D 5) of downlink to client, and client is receiving
To after the TCP message of the downlink, the TCP response message (p1, p2, p3, p4, p5) of uplink is sent to server.In conjunction with this implementation
The scheme of example, when the transmission performance of the transmission network between measuring device measuring customer end and server, measuring device can be connect
The TCP response message (p1, p2, p3, p4, p5) that client is sent is received to exist after carrying out delay process to the TCP response message
When preset delay time reaches, TCP response message (p1, p2, p3, p4, p5) is sent to server end.
In above-described embodiment, measuring device receives the TCP response that client is sent and disappears during measuring network parameter
Breath sends TCP response message to server end when reaching preset delay time.In above-mentioned transmission process, due to prolonging
The slow time is the amount of variation, can be adjusted by user according to practical application request, and in each measuring device monitoring network
Transmission rate variation tendency when, require to adjust the delay time so that the transmission rate of network changes, so as to
So that measuring device can measure the peak transfer rate of the network from the transmission rate of variation.Due to above-mentioned measurement method
It only needs to adjust delay time, to change the practical delay character of network, to change the actual transfer rate of network, then into one
The variation tendency of the transmission rate by monitoring network of step, so that it may measure the network parameter that the network can carry, make
The network parameter that must be measured closer to network actual performance parameter, in this way, according to the network parameter and its matching
QoS parameter configuration network, the network performance that the QoS parameter of practical application performance and the network is constrained
It is almost the same, network data packet loss, congestion and delay are avoided, greatly ensure that the normal speed transmission of the network.
