Embodiment Construction

[0040] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0041] The present invention provides a high-efficiency data exchange system between dual hosts, see figure 1 , the hardware for data exchange between the two hosts includes host A, host B and a data exchange card, and the data exchange card is connected to host A and host B respectively through the PCI-E interface.

[0042] see figure 2 , the host converts the physical address of the data switching card into a virtual address accessible by the user mode process through the IOMMU.

[0043] Based on the above system, the present invention provides a method for efficient data exchange between dual hosts, including:

[0044] Establish a mapping relationship between sessions that need to be exchanged in two hosts;

[0045] Based on the map...

Abstract

According to the efficient data exchange system and method between the double hosts, the equipment physical address of the data exchange card is directly mapped to the user mode through the IOMMU technology to be used by the user mode process, frequent copying of data between the user mode and the kernel mode is reduced, and the data receiving and transmitting efficiency is improved; in the data exchange process, the process C and the process D in the host A and the host B respectively directly transmit the virtual address of the session in the session mapping, so that the session searching efficiency is improved; and when the process C or the process D analyzes the message, the validity of the session virtual address is checked firstly, so that process abnormity caused by hostile attacks is avoided.

Description

technical field [0001] The invention relates to a high-efficiency data exchange system and method between dual hosts, belonging to the technical field of data communication. Background technique [0002] The vigorous development of the Internet has brought frequent and large-scale information interaction requirements between private networks and public networks, requiring private networks to have the characteristics of "extensive interconnection and open interaction", and can effectively address the increasingly advanced and organized network boundaries. and persistent malicious attacks. Facing the increasingly severe network security situation, non-network communication is usually used between private networks and public networks, and strong logical isolation protection is implemented for private networks to effectively guarantee the security of private networks. [0003] A system using non-network communication usually adopts the hardware structure of two hosts plus a dat...
