Referring to fig. 1, fig. 1 is a flowchart of a method for generating a label according to an embodiment of the present application, as shown in fig. 1, including the following steps:
step 101, obtaining characteristic information of the first stream.
The method for generating the identifier may be applied to a flow-following detection device, where the first flow may be sent by the first device, the flow-following detection device may be a device for detecting the performance of opening the flow-following for the service to be detected, and in practical application, the flow-following detection device may be integrated with a network manager, a controller, etc. or may be a separate device for detecting the flow-following, etc., and then the characteristic information of the first flow acquired by the flow-following detection device may be sent by the first device. The flow-following detection device may be disposed in the first device, and the flow-following detection device may directly obtain the characteristic information of the first flow from the first device.
Optionally, before the step 101 of obtaining the feature information of the first stream, the method may further include the following steps:
transmitting a stream learning instruction to the first device, wherein the stream learning instruction is used for acquiring characteristic information of the first stream;
wherein the obtaining the characteristic information of the first stream includes:
and receiving characteristic information of the first stream fed back by the first equipment.
The flow learning instruction may enable the first device to perform flow learning, so that the first device obtains feature information of the first flow, and specifically may send a flow learning instruction to the first device to instruct the first device to record message information of an entry, so that the first device obtains some header feature information required by flow detection, and reports the feature information to the flow detection device. It will be appreciated that, for the two-layer service packet, the characteristic information of the first flow may include one or more of a physical port, a source MAC address, a destination MAC address, a VLAN (Virtual Local Area Network ), etc.; for three-layer traffic messages, the characteristic information of the first flow may include one or more of a destination IP address (Internet Protocol Address ), a source IP address, DSCP (Differentiated Services Code Point ), a source port, a destination port, a VLAN, etc. For example: the flow following detection device receives the characteristic information of the service flow 1 and the characteristic information of the service flow 2 sent by the first device, where the characteristic information of the service flow 1 includes: the source IP address is AAA, the destination IP address is BBB, DSCPXXX; the characteristic information of the service flow 2 includes: the source IP address is CCC, the destination IP address is DDD, DSCPXXX.
In some embodiments, the flow-following detection device may be configured to perform flow-following detection on a bidirectional flow, and the first flow identifier and the second flow identifier may identify a forward flow and a reverse flow in the bidirectional flow, respectively.
Step 102, generating a stream-following detection instance, a first stream identifier and a second stream identifier based on the characteristic information of the first stream;
the first stream identifier is an identifier of a first stream sent from a first address to a second address, the stream following detection instance and the first stream identifier are used for a first device to acquire stream following detection data of the first stream, the second stream identifier is an identifier of a second stream sent from the second address to the first address, and the second stream identifier is used for a second device to acquire stream following detection data of the second stream.
It is understood that the first stream is a forward stream, the second stream is a reverse stream, the first address is a source address of the forward stream, the second address is a destination address of the forward stream, the first address is a destination address of the reverse stream, and the second address is a source address of the reverse stream. After the flow following detection device receives the characteristic information of the first flow, the first flow can be used as a forward flow in a bidirectional flow, a first flow identifier is allocated to the first flow, and a second flow identifier is allocated to a reverse flow of the first flow. For example: the characteristic information of the first stream includes: the Flow following detection device may assign two Flow IDs (Flow ID, flow Identity Document) of a forward Flow and a reverse Flow to the bidirectional Flow, for example, the source IP address is AAA, and assign a first Flow ID 100 to the first Flow, and assign a second Flow ID 101 to the second Flow, that is, the reverse Flow of the first Flow (the source IP address is BBB, and the destination IP address is AAA).
The first device and the second device may be devices at two ends of a bidirectional stream, the first device may be a device that transmits the first stream, and the second device may be a device that transmits the second stream, for example: when the flow-following detection example is deployed in the 5G (5 th Generation Mobile Communication Technology, fifth-generation mobile communication technology) base station backhaul scene, the detection example can be deployed at the core network side docking entrance for detecting the downlink flow of the base station; for the detection of the uplink traffic of the base station, a detection instance may be deployed at the access point at the base station side, and the first device and the second device may correspond to the core network side and the base station side at will. That is, the first device may be the core network side, and the second device may be the base station side; alternatively, the first device may be the base station side, and the second device may be the core network side.
Under the condition that the follow-up detection device is deployed in the first device, the first device can directly acquire the follow-up detection instance, the first flow identifier and the second flow identifier generated by the follow-up detection device, so that follow-up detection data of the first flow can be acquired according to the follow-up detection instance and the first flow identifier, a follow-up detection tag can be generated according to the follow-up detection instance and the second flow identifier, and the follow-up detection tag is sent to the second device, so that the second device can acquire follow-up detection data of the second flow according to the received follow-up detection tag and the locally generated follow-up detection instance, and follow-up detection of the bidirectional flow is realized.
Optionally, after generating the on-stream detection instance, the first stream identifier, and the second stream identifier based on the characteristic information of the first stream in step 102, the method may further include the steps of:
and sending the flow-following detection instance, the first flow identifier and the second flow identifier to the first device, wherein the flow-following detection instance and the first flow identifier are used for the first device to acquire flow-following detection data of the first flow, the second flow identifier is used for the first device to generate a flow-following detection tag and send the flow-following detection tag to a second device, and the flow-following detection tag is used for the second device to acquire the second flow identifier.
In some embodiments, in a case where the on-stream detection device is not deployed in the first device, by sending the on-stream detection instance, the first flow identifier, and the second flow identifier to the first device by the on-stream detection device, the first device may obtain on-stream detection data of the first flow based on the on-stream detection instance and the first flow identifier, while the first device may generate the on-stream detection tag based on the second flow identifier, and send the on-stream detection tag to the second device, so that the second device may obtain on-stream detection data of the second flow based on the on-stream detection tag and the on-stream detection instance in the second device, to implement deployment of on-stream detection instances of the first device and the second device, and on-stream detection of bidirectional flows. Optionally, after the first device acquires the stream following detection data of the first stream, the stream following detection data of the first stream may be sent to the stream following detection device; after the second device acquires the stream following detection data of the second stream, the stream following detection data of the second stream may be sent to the stream following detection device. Specifically, the first device may generate an In-band OAM (In-band operation administration and maintenance) instance according to the on-stream detection instance and the first stream identifier, and acquire on-stream detection data of the first stream using the In-band OAM instance, where the on-stream detection data may include data such as a packet loss rate, a delay, and the like. The second device may also generate a reverse flow detection instance directly according to the flow detection instance and the second flow identifier, and acquire flow detection data of the second flow using the reverse flow detection instance.
The flow-following detection tag is generated by the first device based on the second flow identifier, so that after the second device receives the flow-following detection tag, the flow-following detection tag can be parsed to obtain the second flow identifier. Further, the second device may obtain the flow-following detection data of the second flow based on the locally generated flow-following detection instance and the second flow identifier.
It will be appreciated that the second device may obtain the flow-following detection data of the second flow based on the flow-following detection instance and the second flow identifier, and the flow-following detection instance and the second flow identifier obtained by the second device may be sent by the first device in a flow-following manner, thereby simplifying the configuration of flow-following detection.

The flow-following detection device sends the flow-following detection instance, the first flow identifier and the second flow identifier to the first device, so that the first device can detect the flow of the first flow, the first device can send the flow-following detection tag to the second device along with the flow, the second device can analyze the received flow-following detection identifier to obtain the second flow identifier, and the flow-following detection of the second flow is realized through the generated flow-following detection instance, so that the flow-following detection process is further simplified.
Optionally, after generating the on-stream detection instance, the first stream identifier, and the second stream identifier based on the characteristic information of the first stream in step 102, the method may further include the steps of:
transmitting the flow-along detection instance and the first flow identification to the first device;
the flow-along detection instance and the second flow identification are transmitted to a second device.
As another embodiment, the flow-following detection device may send the corresponding flow identifier and the flow-following detection instance to the first device and the second device, respectively, so that the first device may obtain flow-following detection data of the first flow, and the second device may obtain flow-following detection data of the second flow.
In this embodiment, the flow-following detection instance and the first flow identifier may be sent to the first device, and the flow-following detection instance and the second flow identifier may be sent to the second device, so that the first device and the second device may implement flow-following detection of the first flow and the second flow, respectively.
Optionally, the on-stream detection instance includes an on-stream detection enable flag of the reverse stream;
The stream following detection enabling mark of the reverse stream is used for enabling the second device to carry out stream following detection so as to acquire stream following detection data of the second stream.
Wherein the stream-following detection instance and the stream-following detection tag may be transmitted by the first device to the second device along with the first stream.
In this embodiment, the deployment of the first device and the second device concurrent detection instance is implemented by sending the concurrent detection instance to the first device and sending, by the first device, the concurrent detection instance and the concurrent detection tag to the second device, where the concurrent detection enable flag of the reverse flow is used to enable the second device to perform concurrent detection, so as to obtain concurrent detection data of the reverse flow.
In this embodiment of the present application, an on-stream detection instance, a first stream identifier, and a second stream identifier are generated based on feature information of the first stream, where the first stream identifier is an identifier of the first stream sent from a first address to a second address, the on-stream detection instance and the first stream identifier are used for a first device to obtain on-stream detection data of the first stream, the second stream identifier is an identifier of the second stream sent from the second address to the first address, and the on-stream detection instance and the second stream identifier are used for a second device to obtain on-stream detection data of the second stream. Therefore, the first stream identifier can be respectively allocated to the first stream sent from the first address to the second address based on the acquired characteristic information of the first stream, and the second stream identifier can be respectively allocated to the second stream sent from the second address to the first address, namely, the forward stream and the reverse stream in the bidirectional stream are respectively allocated with the stream identifier, so that the first device and the second device can respectively realize the follow-up detection of the bidirectional stream, and the follow-up detection at two ends of the bidirectional stream is simplified.
Optionally, the on-stream detection instance further includes a detection period;
the detection period is used for enabling the first device to acquire the flow following detection data of the first flow according to the detection period, and is used for enabling the second device to acquire the flow following detection data of the second flow according to the detection period.
The detection period may be set according to a preset time interval, and specifically may be determined according to an actual requirement of flow detection.
In this embodiment, by issuing the flow-following detection instance, the first device may obtain flow-following detection data of the first flow according to the detection period, and the second device may obtain flow-following detection data of the second flow according to the detection period.
Optionally, after generating the on-stream detection instance, the first stream identifier, and the second stream identifier based on the characteristic information of the first stream in step 102, the method further includes:

For example: the characteristic information of the reverse flow generated by the flow following detection device comprises: the source IP address is DDD, the destination IP address is CCC, and a Flow ID 201 is allocated; the received characteristic information of the service flow N comprises: the source IP address is EEE, the destination IP address is FFF, and the Flow ID 201 indicates that the characteristic information of the reverse Flow is not matched with the characteristic information of the received service Flow N, and the Flow following detection device deletes the related Flow ID, the characteristic information and the detection instance.
It is understood that the reverse flow characteristic information is generated from the characteristic information of the first flow, that is, the source address in the reverse flow characteristic information is the destination address of the first flow, and the destination address in the reverse flow characteristic information is the source address of the first flow, and whether the flow following detection data of the second flow is accurate or not can be determined by comparing whether the reverse flow characteristic information matches the characteristic information of the second flow sent by the second device.
If the flow identifier of the second flow is consistent with the flow identifier of the second flow, and if the reverse flow characteristic information and the characteristic information of the second flow do not match, in some embodiments, if the first device and the second device have completed flow-following detection, that is, the flow-following detection device has acquired flow-following detection data of the first flow and flow-following detection data of the second flow, then the flow-following detection data of the first flow and the flow-following detection data of the second flow need to be deleted; correspondingly, the second device also needs to delete the stream following detection data of the second stream acquired by the second device based on the received information deleting instruction.
Optionally, if the flow identifier of the second flow is consistent with the flow identifier of the second flow, the second flow may be determined to be the reverse flow corresponding to the first flow if the reverse flow characteristic information is matched with the characteristic information of the second flow, so that the first device may obtain, based on the follow-up detection instance and the first flow identifier, follow-up detection data of the first flow, and the second device may obtain, based on the follow-up detection instance and the follow-up detection tag, follow-up detection data of the second flow, where the follow-up detection data of the second flow is the reverse flow follow-up detection data of the first flow, so as to implement follow-up detection of the first flow and the second flow. For example: the characteristic information of the reverse flow generated by the flow following detection device comprises: the source IP address is BBB, the destination IP address is AAA, and a Flow ID 101 is allocated; the received characteristic information of the service flow N comprises: the source IP address is BBB, the destination IP address is AAA, and the Flow ID 101 indicates that the characteristic information of the reverse Flow matches the characteristic information of the received traffic Flow N.
