Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
It can be known from the above background art that the bytes occupied by the non-extension field of the existing VPN transmission protocol are the bytes in the packet header, so that more bytes are occupied by the non-extension field, which results in more bytes occupied by the packet header, and more bytes occupied by the packet header result in a larger proportion of the bytes occupied by the packet header in the packet, thereby resulting in a low bandwidth utilization. For example, the header of the IPV4 transmission protocol is generally about 60 bytes, and if the packet has 64 bytes in total, only the header occupies 60 bytes, so that the bandwidth utilization rate is only about 50%, and the bandwidth utilization rate is very low.
Therefore, embodiments of the present invention provide an information transmission method, apparatus, terminal, system, and storage medium, which can reduce bytes in a packet header that a non-extensible field in a transmission protocol needs to occupy, thereby improving a bandwidth utilization rate and extensibility.
As shown in fig. 1, an embodiment of the present invention provides a flowchart of an information service method. The information service method comprises the following steps:

In the process of executing step S101, the message sending end and the message receiving end establish a VPN connection.
S102: the message sending end determines a message sample, and the intranet information of the packet head of the message sample comprises first information.
It should be noted that the first information may be any one or more of an IP header, a VPN quintuple, and a data packet header in the packet header, and the first information may also include other contents in the intranet information, which may be set according to practical applications, and the embodiment of the present invention is not limited.
S103: and the message sending end transmits the determined message sample to the message receiving end.
In the process of specifically executing step S103, after determining the message sample, the message sending end transmits the determined message sample to the message receiving end.

In the specific process of executing step S104, after receiving the message sample transmitted by the message sending end, the message receiving end obtains the first information in the message sample based on the preset information obtaining rule. For example, when the first information in the message sample is an IPv6 quintuple in the intranet information of the packet header, the message receiving end obtains an IPv6 quintuple in the message sample after receiving the message sample transmitted by the message transmitting end.
S105: and the message receiving end processes the first information according to a preset processing rule to obtain second information and generates a second corresponding relation.
And the second corresponding relation represents that the first information corresponds to the second information.

In the process of specifically executing step S105, the message receiving end processes the first information according to a preset Hash algorithm to obtain a Hash value, uses the obtained Hash value as the second information, and generates a second correspondence for representing correspondence between the first information and the second information.

It should be noted that the preset bits may be bits 3 to 39 in the packet header of the packet, and when the preset bits may be bits 3 to 39 in the packet header of the packet, the information of the preset bits is the information in bits 3 to 39 in the packet header of the packet. The present invention can be set according to practical applications, and the embodiments of the present invention are not limited.
S107: and the message sending end processes the target first information according to a preset processing rule to obtain target second information.
It should be noted that the target second information is smaller than the target first information.
It should be noted that the preset processing rule may be a Hash algorithm, and when the preset processing rule is the Hash algorithm, the target first information is processed according to the preset processing rule to obtain a Hash value, and the obtained Hash value is used as the target second information.
In the process of specifically executing step S107, the message sending end performs Hash calculation on the target first information according to a preset Hash algorithm to obtain a Hash value of the target first information, and uses the Hash value of the target first information as the target second information.
S108: and the message sending end replaces the target first information in the message with the target second information to generate a target message.
In the process of specifically executing step S108, after the message sending end processes the target first information according to the preset Hash algorithm to obtain the Hash value of the target first information, the obtained Hash value of the target first information is used as the target second information to replace the target first information in the message, so as to generate the target message.
It should be noted that the target message is smaller than the message.
S109: and the message sending end transmits the target message to the message receiving end.
S110: and the message receiving end determines first information corresponding to the target second information in the target message according to the preset corresponding relation between the first information and the second information.
It should be noted that, according to the preset correspondence between the first information and the second information, the message receiving end determines that the first information corresponding to the target second information in the target message information is the same as the target first information in the packet header of the message sending end.
S111: and the message receiving end replaces the determined first information with the target second information in the target message to obtain a message.
Further, in the embodiment of the present invention, the preset information obtaining rule adopted when the message sending end and the message receiving end obtain the first information from the message is the same, and the preset processing rule adopted when the message sending end and the message receiving end process the obtained first information to obtain the second information is also the same, so that the message finally obtained by the message receiving end is the same as the message sent by the message sending end.

Further, in the information transmission method provided in the embodiment of the present invention, after the connection is established between the message sending end and the message receiving end, the message sending end not only transmits the determined message sample to the message receiving end, so that the message receiving end establishes the second corresponding relationship, but also processes the message sample, and establishes the first corresponding relationship at the message sending end, referring to fig. 3, which specifically includes the following steps:
