Fig. 2 is a flowchart of a message processing method according to an embodiment of the present application.
In a first aspect, referring to fig. 2, an embodiment of the present application provides a packet processing method, which is applied to a first routing node, and the method includes:
In this embodiment of the present application, the received message may be sent by the first client terminal, or may be sent by a network element node on the network side. The first client terminal is, for example, client terminal a in fig. 1, and the network element node on the network side is, for example, any one of router R1, base station 1, core network element C, base station 2, router R2, and the like in fig. 1.
The embodiment of the present application does not limit the specific type of the packet, that is, the packet may be any type of packet. For example, the data packet may be a data packet for transmitting data, or the control packet may be a control packet for sending a control command, and so on.
In the embodiment of the present application, whether to add the first timestamp information to the packet depends on a specific application scenario, and in the embodiment of the present application, when a part or all of routing nodes on a data path between the first client terminal and the second client terminal receive the packet, the packet may be correspondingly processed by using the packet processing method of the embodiment of the present application, and the packet may be sequentially transmitted from a side close to the first client terminal to a side close to the second client terminal, so as to implement troubleshooting of a delay problem of the data path between the first client terminal and the second client terminal. Specifically, which routing nodes to execute the message processing method according to the embodiment of the present application may be determined according to actual situations, and configured with corresponding routing nodes to implement the method.
Therefore, the routing node can know whether first timestamp information needs to be added to the message or not according to the configuration information; the configuration information is used for indicating whether first time stamp information needs to be added to the message or not.
For example, for a Transmission Control Protocol (TCP) message, due to the existence of a packet loss retransmission mechanism, the latency problem is not required to be checked by adding first timestamp information, and for a User Datagram Protocol (UDP) message, the latency problem is required to be checked by adding first timestamp information.
The following two cases are described as specific implementation processes for adding the first timestamp information to the packet.
In case one, the received message is sent by the first client terminal.
For case one, in some exemplary embodiments, the adding the first timestamp information to the packet includes: intercepting the message at an application layer; acquiring application layer information of the message; adding the first timestamp information in the application layer information.
For case one, in some exemplary embodiments, the application layer information includes the data content of the transmission.
For case one, in some exemplary embodiments, the transmission time information includes at least one of: and receiving the time information of the message and sending the time information of the message. That is, the first timestamp information includes at least one of: and the first routing node receives the time information of the message and the time information of the message sent by the first routing node.
For case one, in some exemplary embodiments, said adding the first timestamp information in the application layer information comprises:
adding the first timestamp information at the forefront of the application layer information.
For case one, in some exemplary embodiments, said adding the first timestamp information in the application layer information comprises:
and adding the first time stamp information at the middle position of the application layer information.
For case one, in some exemplary embodiments, said adding the first timestamp information in the application layer information comprises:
and adding the first time stamp information at the end of the application layer information.
For case one, in some exemplary embodiments, adding the first timestamp information at the forefront of the application layer information includes:
first timestamp information is added before the first field of the application layer information.
For case one, in some example embodiments, adding the first timestamp information at the end of the application layer information comprises:
first timestamp information is added after the last field of the application layer information.
For case one, in some exemplary embodiments, said adding the first timestamp information at an intermediate position of the application layer information comprises:
adding the first timestamp information between any two fields of the application layer information;
or, adding 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 to say, the first timestamp information may be added in any position of the application layer information, but in some cases, if the packet is relatively large, the packet needs to be segmented in the transmission process, and then, because the application layer information located behind the segmented packet cannot be identified, the first timestamp information should be added in the front position of the application layer information as much as possible for the case of segmenting the packet, so that the first timestamp information is still located in the first segment of the packet after the segmentation.
For example, N is the number of fields of the application layer information in the first segment of the packet.
For case one, in some exemplary embodiments, information, for example, in a format of "tm = value", which is added first time stamp information, may be added in the application layer information.
And in the second situation, the received message is sent by the network element node on the network side.
For the second case, in some exemplary embodiments, the adding the first timestamp information to the packet includes: second timestamp information is added into the message, and the first routing node is not a routing node directly connected with a second client terminal; wherein the second timestamp information comprises: and the second routing node transmits the transmission time information of the message.
For the second situation, in this embodiment of the application, the transmission time information of the second routing node for the packet may refer to the transmission time information of one routing node for the packet, or may refer to the transmission time information of two or more routing nodes for the packet.
For case two, in some exemplary embodiments, the determining whether the second timestamp information has been added to the message includes:
intercepting a message at an application layer; acquiring application layer information of a message; judging whether second timestamp information is added in the application layer information; under the condition that the second timestamp information is added in the application layer information, determining that the second timestamp information is added in the message; and under the condition that the second timestamp information is not added in the application layer information, determining that the second timestamp information is not added in the message.
For case two, in some exemplary embodiments, it may be determined whether second timestamp information has been added to the application layer information by determining whether information in the format of "tm = value" exists in the application layer information; determining that second time stamp information has been added to the application layer information in a case where information in a format of "tm = value" exists in the application layer information; in the case where information in the format of "tm = value" does not exist in the application layer information, it is determined that the second time stamp information is not added to the application layer information.
For case two, in some exemplary embodiments, the adding the first timestamp information to the packet includes:
and modifying the second timestamp information in the application layer information into the first timestamp information.
For case two, in some exemplary embodiments, said adding the first timestamp information to the packet includes:
adding the first timestamp information in the application layer information.
For example, if delay analysis is performed on each routing node, the second timestamp information in the application layer information may be modified to the first timestamp information, that is, when performing delay analysis on the following routing node, the second timestamp information carried in the packet received by the routing node is not needed, but only the first timestamp information added by the routing node is needed, so that the second timestamp information does not need to be retained in the packet, and meanwhile, bandwidth resources are also saved. In this case, the transmission time information of the second routing node for the packet includes only the transmission time information of one routing node for the packet. Of course, it is also possible to add the first time stamp information in case the second time stamp information is retained in the application layer information. In this case, the transmission time information of the second routing node for the packet may refer to the transmission time information of one routing node for the packet, or may refer to the transmission time information of two or more routing nodes for the packet.
If the delay analysis is only performed on part of the routing nodes, for the routing node which adds the first timestamp information between two adjacent routing nodes performing the delay analysis, the second timestamp information needs to be retained in the application layer information, that is, the first timestamp information needs to be added in a new field of the application layer information, so that the routing node performing the delay analysis can know the delay condition of each routing node which adds the first timestamp information.
For case two, in some exemplary embodiments, the transmission time information includes at least one of: and receiving the time information of the message and sending the time information of the message. That is, the second time stamp information includes at least one of: and the second routing node receives the time information of the message and the time information of the message sent by the second routing node.
For case two, in some exemplary embodiments, said adding the first timestamp information in the application layer information comprises:
adding the first timestamp information at the forefront of the application layer information.
For case two, in some exemplary embodiments, said adding the first timestamp information in the application layer information comprises:
and adding the first time stamp information at the middle position of the application layer information.
For case two, in some exemplary embodiments, said adding the first timestamp information in the application layer information comprises:
and adding the first time stamp information at the end of the application layer information.
For case two, in some exemplary embodiments, adding the first timestamp information at the forefront of the application layer information comprises:
first timestamp information is added before the first field of the application layer information.
For case two, in some example embodiments, adding the first timestamp information at the end of the application layer information comprises:
first timestamp information is added after the last field of the application layer information.
For case two, in some exemplary embodiments, said adding the first timestamp information at the intermediate position of the application layer information comprises:
adding the first timestamp information between any two fields of the application layer information;
or, adding 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 to say, the first timestamp information may be added in any position of the application layer information, but in some cases, if the packet is large, the packet needs to be segmented in the transmission process, because the application layer information located behind the segmented packet cannot be identified, the first timestamp information should be added in the front position of the application layer information as much as possible for the case of segmenting the packet, so that the first timestamp information is still located in the first segment of the packet after the segmentation.
For example, N is the number of fields of the application layer information in the first segment of the packet.
For case two, in some exemplary embodiments, information, for example, in the format of "tm = value", which is the added first timestamp information, may be added in the application layer information.
In this embodiment of the present application, the packet to which the first timestamp information is added is sent to a next routing node, where the next routing node is a routing node closer to the second client terminal.
In some exemplary embodiments, in a case that the message has second timestamp information added thereto, 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 sending the message with the second timestamp information deleted to the second client terminal.
In some exemplary embodiments, in a case that the received packet is sent by a network element node on the network side, after receiving the packet, the method further includes:
calculating time delay according to the first time stamp information and the second time stamp information;
and sending alarm information under the condition that the time delay is greater than a preset threshold value.
In the embodiment of the present application, after obtaining a routing node whose delay is greater than a preset threshold, the reason why the delay exceeds the standard may be analyzed by checking the utilization rate of a Central Processing Unit (CPU) of the routing node, the size of an idle memory, and the like, so as to implement the analysis to a code layer for improvement.

In order to more clearly describe the process of transferring and analyzing the timestamp information, the following still takes the example in fig. 1 as an example to describe in detail the transferring and analyzing of the timestamp information between different routing nodes, and the example is only for convenience of illustration and is not used to limit the scope of the embodiments of the present application.
Example 1
In this example, both the client terminal a and the client terminal B are power devices, the frequency of sending messages by the power devices is very high (2000 messages per second at the lowest), and time modules in the devices detect the time delay of messages sent by the peer devices for statistics, and an alarm will be given when the time delay exceeds 80 milliseconds (ms), which never happens in a 4G network. Because the requirement on the delay index is extremely high, the traditional method is difficult to find out and position, and therefore, each routing node between the client terminal A and the client terminal B needs to support the addition of the timestamp information.
In this example, in the process of sending a packet to the client terminal B by the client terminal a, each routing node on the data path between the client terminal a and the client terminal B adds the time for receiving the packet by the routing node, and performs delay analysis.

Example 2
In this example, both the client terminal a and the client terminal B are power devices, the frequency of sending messages by the power devices is very high (2000 messages per second at the lowest), and time modules in the devices detect the time delay of messages sent by the peer devices for statistics, and an alarm will be given when the time delay exceeds 80 milliseconds (ms), which never happens in a 4G network. Because the requirement on the delay index is extremely high, the traditional method is difficult to find out and position, and therefore, each routing node between the client terminal A and the client terminal B needs to support the addition of the timestamp information.
In this example, in the process of sending a packet from the client terminal a to the client terminal B, each routing node on the data path between the client terminal a and the client terminal B adds the time for receiving the packet by the routing node, and only performs delay analysis on the router R2.
