Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0025] The embodiment of the present invention provides a method for transmitting network data, and the method can be applied to security equipment. In this solution, a security device is configured with at least two CPUs, and two gatekeeper subsystems (which may be referred to as a first gatekeeper subsystem and a second gatekeeper subsystem) are installed in the security device. The first gatekeeper subsystem and the second gatekeeper subsystem run on different CPUs, that is, the ...

Abstract

Embodiments of the invention provide a method and a device for transmitting network data, and belong to the technical field of communication. According to the method, safety equipment comprises a first CPU, a second CPU and a memory; a first gateway subsystem runs on the first CPU, and a second gateway subsystem runs on the second CPU, wherein the first CPU uses the first gateway subsystem to create a plurality of first virtual devices, the second CPU uses the second gateway subsystem to create a plurality of second virtual devices corresponding to the first virtual devices respectively, and amemory area shared by the first virtual devices and the second virtual devices corresponding to the first virtual devices is arranged in the memory; each first virtual device receives a service message sent by a network device in the first network, extracts effective data in the service message, and stores the effective data in a data writing area of the first virtual device in the memory area; and each second virtual device reads the effective data from the data writing area of the corresponding first virtual device and forwards the effective data. By the adoption of the method and the device, the network layout cost can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for transmitting network data. Background technique [0002] In the prior art, it is usually necessary to use a gatekeeper device to cut off the link layer connection between the networks on the circuit, so as to realize the disconnection of the two networks at the link layer, so as to disconnect the connection of the two networks. The gatekeeper device often includes a first gatekeeper sub-device connected to a first network (such as an internal network), a second gatekeeper sub-device connected to a second network (such as an external network) and isolation hardware, the first gatekeeper sub-device It is connected with the second gatekeeper sub-device through isolation hardware. [0003] Among them, the gatekeeper sub-device is used to realize the connection of network protocols, and the service packets sent by the network equipment in ...
