5. in this way, until the accuracy is 1% (the accuracy can be configured), a certain set value of the flow rate is passed, and the flow rate is the throughput of the tested network in the frame length;
6. and judging whether all the frame lengths (64, 128, 256, 512, 1024, 1280 and 1518) are tested, if so, turning to the step 7, and if not, turning to the step 1, and replacing the length of another message.

Specifically, the delay data may be determined according to a comparison between the receiving time of the current response packet and a preset receiving time. Of course, other ways of calculating the delay data are within the scope of the present embodiment.
Optionally, when the detection packet includes a jitter detection packet, analyzing forwarding performance of the service traffic in the network includes: and the sending end equipment determines a jitter result corresponding to the flow according to the time delay data.

Example 2
In this embodiment, a method for detecting traffic is provided, which has already been described and will not be described again. Fig. 4 is a flow chart of an analysis of a flow rate according to an embodiment of the present invention, as shown in fig. 4, the flow chart includes the following steps:

Specifically, according to the formats of the detection packets described in embodiment 1 and illustrated in fig. 2 and 3, by performing access control table ACL matching, the reflection-side device verifies the verify code in the detection packet when performing verification, and identifies the feature code when performing identification. By authentication and identification, the reflection end equipment can distinguish the common service message from the flow detection service message, does not affect normal service, and can ensure the safety of current flow detection through verification. In addition, the detection message is updated in real time according to the service requirement. Therefore, the use of the detection message of the old version can be avoided through verification, and resources are saved.

In addition, it should be noted that the reflection-end device may send the message back by exchanging the message information such as IP and Mac in the received detection message. Fig. 5 is a schematic diagram of loopback transmission of a message according to an embodiment of the present invention. As shown in fig. 5. A is a sending terminal device, and B is a reflecting terminal device. The MAC B and IP B as the target in the receiving frame of the message are detected, and the MAC A and IP A are exchanged in the response message. Similarly, MAC a, IP a, which is the source, is exchanged as MACB, IP B. Of course, it is also within the scope of the message of the present embodiment to exchange only MAC, or only IP. And will not be described herein in more detail. Therefore, by the method, the flow detection can be completed under the condition of not adding extra message resources, so that the resources can be saved.
In addition, in order to better understand the technical solutions described in the above embodiments, the following scenarios are also provided for reference:
scene 1:
step 1: in the engineering implementation phase, the flow needs to be constructed as required, and an L3 message is constructed at the transmitting end through a template, wherein the message comprises a PDU part. Particularly, for the time delay and jitter test messages, the first timestamp field is filled with the sent timestamp, and in addition, all the test messages can calculate the correct verify code value according to the algorithm, and the messages are supplemented, and the like.
Step 2: and the reflecting end receives the message and identifies and reflects the message. The reflection end identifies the test flow and mainly realizes the verification of PDU verify code and the field comparison of PDU by ACL matching. And according to the related configuration modification message, such as the exchange IP and the mac, sending the message in a loopback mode. As shown in the following figures. If the test message is the time delay and jitter test message, the receiving time is counted on the second time frame and the third time frame.
And step 3: the transmitting end receives the message which is transmitted by the network and reflected by the reflecting end, and the message is identified and processed. And the throughput rate is calculated according to the sending time and the received message. The packet loss rate can be obtained by calculating the difference between the number of the sent and received messages. The time delay data can be obtained by calculation according to the time stamp carried in the message, and the jitter can be obtained by the time delay data. After the data are obtained, the data can be uploaded to a control platform, and the data are displayed through an interface.
Scene 2:
step 1: the existing network flow test can adopt the method that a corresponding message is constructed at a transmitting end or a tested message is captured and copied according to the configuration, for the copied message, if the message is a TCP message or a UDP message, correct PDU data content is added behind the header of the TCP message or the UDP message, and other messages add the PDU to a part l 4. Particularly, for the delay and jitter test messages, the first timestamp field is filled with the sent timestamp, and in addition, all the test messages can calculate the correct verifycode value according to the algorithm, and the messages are supplemented.
Step 2: and the reflecting end receives the message and identifies and reflects the message. The reflection end identifies the test flow and mainly realizes the verification of PDU verify code and the field comparison of PDU by ACL matching. And according to the related configuration modification message, such as the exchange IP and the mac, sending the message in a loopback mode. As shown in the following figures. If the test message is the time delay and jitter test message, the receiving time is counted on the second time frame and the third time frame.
And step 3: the transmitting end receives the message which is transmitted by the network and reflected by the reflecting end, and the message is identified and processed. And the throughput rate is calculated according to the sending time and the received message. The packet loss rate can be obtained by calculating the difference between the number of the sent and received messages. The time delay data can be obtained by calculation according to the time stamp carried in the message, and the jitter can be obtained by the time delay data. After the data are obtained, the data can be uploaded to a control platform, and the data are displayed through an interface.
Scene 3:
step 1: the PTP protocol is used for time synchronization in the whole network.
Step 2: other processing is the same as the implementation steps, and due to the adoption of PTP time synchronization, unidirectional delay and jitter can be calculated through the time stamps received by the reflecting end and sent by the transmitting end.
