Gateway structure for communicating heterogeneous interconnection media and configuration method

Abstract

The invention relates to a gateway structure for communicating heterogeneous interconnection media and a configuration method. The Gateway structure for communicating heterogeneous interconnection media comprises at least one PCI-E (Peripheral Component Interconnect Express) cluster node and a PCI-E non-transparent bridge gateway; the PCI-E non-transparent bridge gateway includes a standard Ethernet interface and a PCI-E network interface; the PCI-E cluster nodes are connected with the PCI-E non-transparent bridge gateway through the PCI-E network interface; and the PCI-E non-transparent bridge gateway is connected with the Ethernet and / or Internet through the standard Ethernet interface. With the gateway structure for communicating heterogeneous interconnection media and the configuration method of the invention adopted, communication between a PCI-E network cluster and the Ethernet or the Internet can be realized; any node in the PCI-E network cluster can freely access the resources of the Internet, while the Internet does not see the PCI-E network cluster node, and therefore, the use of the PCI-E network cluster can be more convenient, the data security of the PCI-E network cluster can be ensured and will not be attacked by external Internets.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a gateway structure and configuration method for Unicom heterogeneous interconnection media. Background technique [0002] PCI Express (Peripheral Component Interconnect Express, referred to as PCI-E, is a high-speed serial computer expansion bus standard) as one of the most important buses inside the computer, used to connect various basic components inside the computer, and at the same time provide the computer A unified interface for various additional boards. [0003] In recent years, the PCI-SIG organization has continued to promote the upgrading and popularization of the PCI-E standard. The current mainstream PCI-E third generation already supports point-to-point unidirectional transmission at a rate of 8GT / s, and the upcoming fourth generation of PCI-E will support a rate of 16GT / s. The commonly used PCI-E interface is 8-channel or 16-channel, so the one-way tra...

Problems solved by technology

[0007] However, whether it is two PCI-E network cluster node interconnection structures or multiple PCI-E network cluster node interconnection structures, due to the lack of interaction channels between small PCI-E network clusters and other external interconnection media, such as mainstream Internet (Ethernet Network) communication channel, which leads to the inability of the nodes inside the cluster to access the Internet, which may cause inconvenience in the actual application process
