FIG. 2 is a flowchart of a packet processing method provided by an embodiment of the present disclosure.

In the first aspect, referring to FIG. 2 , an embodiment of the present disclosure provides a packet processing method, which is applied to a first routing node, and the method includes:

Step 200: Receive a message.

In this embodiment of the present disclosure, the received message may be sent by the first client terminal, or may be sent by the network element node on the network side. The first client terminal is client terminal A as shown in FIG. 1 , and the network-side network element node is any one of router R1 , base station 1 , core network element C, base station 2 , router R2 , etc. as shown in FIG. 1 .

The embodiment of the present disclosure does not limit the specific type of the message, that is, the message may be any type of message. For example, it may be a data message for transmitting data, or a control message for sending a control command, and so on.

Step 201: Add the first timestamp information to the packet in the case where the first timestamp information needs to be added to the packet; wherein the first timestamp information includes: the first route The transmission time information of the message by the node.

In this embodiment of the present disclosure, whether it is necessary to add the first timestamp information to the packet depends on a specific application scenario. In the embodiment of the present disclosure, when part or all of the routing nodes on the data path between the first client terminal and the second client terminal receive the packet, the packet processing method according to the embodiment of the present disclosure may be used to process the packet. Corresponding processing is sequentially transmitted from the side close to the first client terminal to the side of the second client terminal, thereby realizing the investigation of the delay problem of the data path between the first client terminal and the second client terminal. Specifically, on which routing nodes the packet processing method of the embodiment of the present disclosure is executed may be determined according to the actual situation, and the corresponding routing nodes are configured to implement.

In this embodiment, the routing node may know whether the first timestamp information needs to be added to the packet according to the configuration information, wherein the configuration information is used to indicate whether the first timestamp information needs to be added to the packet.

For example, the Transmission Control Protocol (TCP, Transmission Control Protocol) message does not need to add the first timestamp information to troubleshoot the delay due to the packet loss retransmission mechanism, while the User Datagram Protocol (UDP, User Datagram Protocol) message In this paper, the delay problem needs to be checked by adding the first timestamp information.

The following describes the specific implementation process of adding the first timestamp information to the packet in two cases.

Case 1: The received message is sent by the first client terminal.

For case 1, in some exemplary embodiments, adding the first timestamp information to the packet includes: intercepting the packet at the application layer; acquiring application layer information of the packet; Add the first time stamp information to .

For case one, in some exemplary embodiments, the application layer information includes the transmitted data content.

For case 1, in some exemplary embodiments, the transmission time information includes at least one of the following: time information for receiving the packet, and time information for sending the packet. That is, the first timestamp information includes at least one of the following: time information when the first routing node receives the packet, and time information when the first routing node sends the packet.

For the first case, in some exemplary embodiments, the adding the first timestamp information to the application layer information includes: adding the first timestamp information to the front of the application layer information.

For the first case, in some exemplary embodiments, the adding the first timestamp information to the application layer information includes: adding the first timestamp information at a middle position of the application layer information.

For the first case, in some exemplary embodiments, the adding the first timestamp information to the application layer information includes: adding the first timestamp information at the end of the application layer information.

For the first case, in some exemplary embodiments, adding the first timestamp information to the front of the application layer information includes: adding the first timestamp information before the first field of the application layer information.

For the first case, in some exemplary embodiments, adding the first timestamp information at the end of the application layer information includes: adding the first timestamp information after the last field of the application layer information.

For case 1, in some exemplary embodiments, the adding the first timestamp information in the middle of the application layer information includes: adding the first timestamp information between any two fields of the application layer information ; or, add the first timestamp information between any two fields of the first N fields of the application layer information; wherein, N is an integer greater than or equal to 2.

That is, the first timestamp information may be added in any position of the application layer information. However, in some cases, if the packet is relatively large and the packet needs to be segmented during transmission, the application layer information behind the segment cannot be identified. Therefore, in the case of segmenting the packet, try to add the first timestamp information in front of the application layer information, so that the first timestamp information is still located in the first segment of the packet after segmentation.

For example, the above N is the number of fields of application layer information in the first segment of the packet.

For the first case, in some exemplary embodiments, information in the format of, for example, "tm=value" may be added to the application layer information, where value is the added first timestamp information.

Case 2: The received packet is sent by the network element node on the network side.

For the second case, in some exemplary embodiments, in the case that the first timestamp information needs to be added to the packet, the method further includes: the second timestamp information has been added to the packet, and the first timestamp information has been added to the packet. A routing node is not a routing node directly connected to the second client terminal; wherein, the second timestamp information includes: transmission time information of the packet by the second routing node.

For the second case, in the embodiment of the present disclosure, the transmission time information of the packet by the second routing node may refer to the transmission time information of the packet by one routing node, or may refer to the transmission time information of two or more routing nodes. The transmission time information of the text.

For the second case, in some exemplary embodiments, judging whether the second timestamp information has been added to the packet includes: intercepting the packet at the application layer; acquiring application layer information of the packet; judging whether the application layer information has been The second time stamp information is added; if the second time stamp information has been added to the application layer information, it is determined that the second time stamp information has been added to the packet; the second time stamp information is not added to the application layer information In the case of information, it is determined that the second time stamp information is not added to the message.

For the second case, in some exemplary embodiments, it may be determined whether the second timestamp information has been added to the application layer information by judging whether there is information in the format of "tm=value" in the application layer information; in the application layer information If there is information in the format of "tm=value" in the application layer information, it is determined that the second timestamp information has been added to the application layer information; in the case of no information in the format of "tm=value" in the application layer information, it is determined that The second timestamp information is not added to the application layer information.

For the second case, in some exemplary embodiments, the adding the first timestamp information to the packet includes: modifying the second timestamp information in the application layer information to the first timestamp information.

For the second case, in some exemplary embodiments, the adding the first timestamp information to the packet includes: adding the first timestamp information to the application layer information.

For example, if delay analysis is performed on each routing node, the second timestamp information in the application layer information can be modified to the first timestamp information. That is to say, the subsequent routing node does not need to use the second timestamp information carried in the packet received by the routing node, but only needs to use the first timestamp information added by the routing node when performing the delay analysis. Therefore, it is not necessary to keep the second timestamp information in the packet, and bandwidth resources are also saved. In this case, the transmission time information of the packet by the second routing node only includes the transmission time information of the packet by one routing node. Of course, it is also possible to add the first time stamp information while retaining the second time stamp information in the application layer information. In this case, the transmission time information of the packet by the second routing node may refer to the transmission time information of one routing node to the packet, or may refer to the transmission time information of two or more routing nodes to the packet.

If the delay analysis is only performed on some routing nodes, the second timestamp information needs to be retained in the application layer information for the routing nodes that add the first timestamp information between two adjacent routing nodes that perform delay analysis. , that is, the first timestamp information needs to be added to a new field of the application layer information, so as to ensure that the routing node performing the delay analysis can know the delay situation of each routing node that adds the first timestamp information.

For the second case, in some exemplary embodiments, the transmission time information includes at least one of the following: time information for receiving the packet, and time information for sending the packet. That is, the second time stamp information includes at least one of the following: time information when the second routing node receives the packet, and time information when the second routing node sends the packet.

For the second case, in some exemplary embodiments, the adding the first timestamp information to the application layer information includes: adding the first timestamp information to the front of the application layer information.

For the second case, in some exemplary embodiments, the adding the first timestamp information to the application layer information includes: adding the first timestamp information at a middle position of the application layer information.

For the second case, in some exemplary embodiments, the adding the first timestamp information to the application layer information includes: adding the first timestamp information at the end of the application layer information.

For the second case, in some exemplary embodiments, adding the first timestamp information to the front of the application layer information includes: adding the first timestamp information before the first field of the application layer information.

For the second case, in some exemplary embodiments, adding the first timestamp information at the end of the application layer information includes: adding the first timestamp information after the last field of the application layer information.

For the second case, in some exemplary embodiments, the adding the first timestamp information in the middle of the application layer information includes: adding the first timestamp information between any two fields of the application layer information ; or, add the first timestamp information between any two fields of the first N fields of the application layer information; wherein, N is an integer greater than or equal to 2.

For the second case, in some exemplary embodiments, information in the format of, for example, "tm=value" may be added to the application layer information, where value is the added first timestamp information.

Step 202: Send the message added with the first timestamp information.

In the embodiment of the present disclosure, the packet after adding the first timestamp information is sent to the next routing node, where the next routing node refers to a routing node that is closer to the second client terminal.

In some exemplary embodiments, when the second time stamp information has been added to the packet, and the first routing node is a routing node directly connected to the second client terminal, the method further includes:

deleting the second timestamp information; and

Send the message after deleting the second timestamp information to the second client terminal.

In some exemplary embodiments, in the case that the received message is sent by the network element node on the network side, after receiving the message, the method further includes:

calculating a delay based on the first timestamp information and the second timestamp information; and

When the time delay is greater than the preset threshold, an alarm message is issued.

The above descriptions are all described for a single execution subject. In order to describe the transmission and analysis process of time stamp information more clearly, the following still takes the example in FIG. For the analysis, the listed examples are only for the convenience of description, and are not used to limit the protection scope of the embodiments of the present disclosure.

Example 1

In this example, both client terminal A and client terminal B are electrical equipment. The frequency of sending packets of this kind of power equipment is very high (minimum 2000 packets per second), and there is a time module inside the equipment to detect the delay of the packets sent by the peer equipment and make statistics, if it exceeds 80 milliseconds (ms), the Alarm, this scene has never been encountered in the 4G network. Due to the extremely high requirements for delay indicators, it is difficult to troubleshoot and locate using traditional methods. Therefore, each routing node between client terminal A and client terminal B needs to support the addition of timestamp information.

In this example, when client terminal A sends a packet to client terminal B, each routing node on the data path between client terminal A and client terminal B adds the time when the routing node receives the packet, and performs Latency analysis.

In this example, as shown in Figure 1, client terminal A is connected to router R1 through a network cable, router R1 performs 5G or Long Term Evolution (LTE, Long Term Evolution) dialing, and client terminal B is also connected to router R2 through a network cable, and router R2 performs For 5G or LTE dial-up, base station 1, core network element C, and base station 2 exist between router R1 and router R2.

As shown in Figure 1, after the router R1 is powered on, it monitors the packets sent by the client terminal A. If a packet sent by client terminal A is received, the packet is intercepted at the application layer, the application layer information of the packet is obtained, and information in the format "tm=value" is added before the first field of the application layer information; =t1, t1 is the time when the router R1 receives the message; the router R1 sends the message to the base station 1 with the information added in the format of "tm=value".

After base station 1 is powered on, it monitors the packets sent by router R1. If the packet sent by router R1 is received, the packet is intercepted at the application layer, the application layer information of the packet is obtained, and it is judged whether there is information in the format of "tm=value" before the first field of the application layer information; If there is no information in the format of "tm=value" in front of the first field of the layer information, the packet is sent to the core network element C; if the first field of the application layer information is in the format of "tm=value" information, then since base station 1 is not a routing node directly connected to client terminal B, the value in the information with the format "tm=value" in front of the first field of the application layer information is modified to t2, and t2 is received by base station 1 time of the message; base station 1 sends the message to core network element C; and base station 1 calculates the total transmission delay between base station 1 and router R1, that is, the difference between t2 and t1; if the difference between t2 and t1 is greater than If the difference between t2 and t1 is less than 10ms, it means that the time delay between base station 1 and router R1 is stable.

After the core network element C is powered on, it monitors the packets sent by the base station 1 . If the packet sent by base station 1 is received, the packet is intercepted at the application layer, the application layer information of the packet is obtained, and it is judged whether there is information in the format of "tm=value" before the first field of the application layer information; If there is no information in the format of "tm=value" in front of the first field of the layer information, the message is sent to base station 2; if there is information in the format of "tm=value" in front of the first field of the application layer information, Then, since the core network element C is not a routing node directly connected to the client terminal B, the value in the information in the format "tm=value" in front of the first field of the application layer information is modified to t3, and t3 is the core network network. The time when element C receives the packet; core network element C sends the packet to base station 2; and core network element C calculates the total transmission delay between core network element C and base station 1, that is, the difference between t3 and t2 If the difference between t3 and t2 is greater than 10ms, an alarm message will be issued; if the difference between t3 and t2 is less than 10ms, it means that the delay between the core network element C and the base station 1 is stable.

After the base station 2 is powered on, it monitors the packets sent by the core network element C. If the packet sent by the core network element C is received, the packet is intercepted at the application layer, the application layer information of the packet is obtained, and whether there is information in the format "tm=value" before the first field of the application layer information ;If there is no information in the format of "tm=value" in front of the first field of the application layer information, send the packet to router R2; if there is information in the format of "tm=value" in front of the first field of the application layer information information, then since base station 2 is not a routing node directly connected to client terminal B, the value in the information in the format of "tm=value" in front of the first field of the application layer information is modified to t4, and t4 is received by base station 2 time of the message; base station 2 sends the message to router R2; and base station 2 calculates the total transmission delay between base station 2 and core network element C, that is, the difference between t4 and t3; if the difference between t4 and t3 is greater than If the difference between t4 and t3 is less than 10ms, it means that the delay between base station 2 and core network element C is stable.

After the router R2 is powered on, it monitors the packets sent by the base station 2. If the packet sent by base station 2 is received, the packet is intercepted at the application layer, the application layer information of the packet is obtained, and it is judged whether there is information in the format of "tm=value" before the first field of the application layer information; If there is no information in the format of "tm=value" in front of the first field of the layer information, the message is sent to the client terminal B; if there is information in the format of "tm=value" in front of the first field of the application layer information , then since router R2 is a routing node directly connected to client terminal B, the information in the format "tm=value" in front of the first field of the application layer information is deleted; router R2 sends the message to client terminal B; and , router R2 calculates the total transmission delay between router R2 and base station 2, that is, the difference between t5 and t4, t5 is the time when router R2 receives the message; if the difference between t5 and t4 is greater than 10ms, an alarm message is issued; if t5 If the difference between t4 and t4 is less than 10ms, it means that the delay between router R2 and base station 2 is stable.

Example 2

In this example, both client terminal A and client terminal B are electrical equipment. The frequency of sending packets of this kind of power equipment is very high (minimum 2000 packets per second), and there is a time module inside the equipment to detect the delay of the packets sent by the peer equipment and make statistics, if it exceeds 80 milliseconds (ms), the Alarm, this scene has never been encountered in the 4G network. Due to the extremely high requirements on the delay index, it is difficult to troubleshoot and locate by traditional methods. Therefore, each routing node between the client terminal A and the client terminal B needs to support the addition of timestamp information.

In this example, when client terminal A sends a packet to client terminal B, each routing node on the data path between client terminal A and client terminal B adds the time when the routing node receives the packet, and only adds the time when the routing node receives the packet. Latency analysis is performed on router R2.

As shown in Figure 1, after the router R1 is powered on, it monitors the packets sent by the client terminal A. If the message sent by the client terminal A is received, the message is intercepted at the application layer, the application layer information of the message is obtained, and the information in the format "tm=value" is added in front of the first field of the application layer information; wherein, value=t1, t1 is the time when the router R1 receives the message; the router R1 sends the message to the base station 1 with the information in the format of “tm=value” added.

After base station 1 is powered on, it monitors the packets sent by router R1.
