Problems solved by technology
[0005] However, in practical applications, it is found that in many cases, the length of the data obtained after the above-mentioned processing is performed on the IP message to be transmitted using the existing IPSec protocol is greater than the length before processing, which affects the compression efficiency of the IP message. This is not conducive to the efficient use of bandwidth transmission resources

Embodiment Construction
[0068] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0069] IPSec is an open standard framework that uses encrypted security services to ensure confidential and secure communications over Internet Protocol (IP) networks.
[0070] The IPSec protocol works on the third layer of the OSI model. The IPSec protocol is not a separate protocol. It provides a complete set of architecture for network data se...

The embodiment of the invention discloses an IP message processing method and device. The method comprises steps of: acquiring a first IP message; determining the total length of the first IP message; comparing the total length of the first IP message with a preset demarcation point length; executing a first processing strategy on the basis of a comparison result indicating that the total length of the first IP message is less than or equal to the preset demarcation point length, wherein the first processing strategy includes encrypting the first IP message and compressing encrypted data; generating a second IP message carrying the encrypted data; and sending the second IP message. The method and the device encrypt the IP message with the total length less than or equal to the preset demarcation point length and then compress the encrypted message, wherein the head of a used encryption protocol is added in the encryption. Since the added head of the encryption protocol is provided with compression space, compression efficiency can be increased.
Description
technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to an IP message processing method and device. Background technique [0002] Currently, the interface bandwidth of communication devices (such as security gateways, hosts, etc.) is fixed. Sometimes in order to improve the service bandwidth, compression technology is often used: when processing a message, the sending device first compresses the message, then sends it out, and decompresses it after receiving it at the peer end. It is hoped that the traffic through this interface can be increased under the condition of fixed interface bandwidth. [0003] In addition, the public is paying more and more attention to the protection of personal privacy, which also promotes the wide application of encryption technology. [0004] The current mainstream Internet encryption protocol is the IPSec (Internet Protocol Security) protocol, and the IPSec protocol uses...
