Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] like figure 1 As shown, the embodiment of the present invention provides a message processing method, including:

[0024] 10. The message processing device receives the first message sent by the upstream network device, where the upstream network device is set in the first network;

[0025] 11. The message processing device judges whether the above-mentioned first message is an illegal message;

[0026] 12. When the above-mentioned first message is an...

Abstract

The embodiment of the invention relates to a message processing method, device and system, wherein the message processing method comprises the steps: the message processing device receives a first message sent by upstream network equipment, wherein the upstream network equipment is arranged in a first network; whether the first message is an illegal message is judged; and when the first message is the illegal message, the message processing device modifies a sensitive field of the first message to obtain a second message and sends the second message to downstream network equipment to ensure that the downstream network equipment discards the second message, wherein the downstream network equipment is arranged in a second network. The message processing method, device and system disclosed by the embodiment of the invention can be convenient for determining whether the downstream network equipment discards the message or other legal message packet loss happens in the network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message processing method, a message processing device and a message processing system. Background technique [0002] At present, in order to ensure the security of network communication, network packets can be filtered through the security device, the filtered illegal packets are directly discarded, and other legal packets are transparently transmitted. Exemplarily, for example, a security device is set between a domestic network (such as the Internet) and an international network, and the security device filters messages from the international network to block illegal messages from the international network from entering The domestic network, other legitimate messages can enter the domestic network smoothly. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] D...
