Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] Reference attached figure 1 , a kind of SCSI interface network data isolation and switch transmission method, adopt following steps:

[0035] Network one (1) and network two (2) are isolated by the data isolation switch (3);

[0036] The data isolation switch (3) is connected to the network one (1) through the high-speed data interface one (5);

[0037] The data isolation switch (3) is connected with the network two (2) through the high-speed data interface two (6);

[0038] The core controller (4) controls the data isolation switch (3) to close on the network one (1) side, and can transmit data between the network one (1) and the data buffer (7);

[0039] The core controller (4) controls the data isolation switch (3) to close on the network two (2) side, and can transmit data between the network two (2) and the data buffer (7);

[0040]The data buffer (7) i...

Abstract

The invention refers to a transmitting method for SCSI interface net data isolation and switch, and the device. It includes a single-blade double-fling electronic switch which is isolates the net oneand the net two, the high-speed data interface which connects the net one with data isolating switch, a high-speed interface which connects the net two with the data isolating switch, the data bufferarea which stores and transfers the data of the net one or the net two, the core control machine which sends the control order to the data isolating switch, the data buffer area can transmits data with the net one and the net two, the two data interfaces are SCSI interface and applies to SCSI-2 or SCSI-3 criterion.

Description

(1) Technical field [0001] The invention relates to a computer network security isolation method and device, in particular to a SCSI interface network data isolation and switching transmission method and its device. (2) Background technology [0002] Due to the increasing loss or destruction of enterprise internal information through the Internet, some organizations that are extremely security-oriented, such as the military, government departments, and financial systems, are all concerned about how to protect internal information from external attacks. my country's National Security Bureau also promulgated and implemented the "Regulations on the Administration of International Networking of Computer Information Systems Confidentiality" on January 1, 2000. Article 6 of Chapter II stipulates that "computer information systems involving state secrets shall not be directly or indirectly related to Connections to the Internet or other public information networks must be physically...
