2 1 The system architecture gateway technology is leading, or the multi host system architecture gat

Landlord: Hello!

I am a manufacturer of isolation gates.

Definitely:"2+1"The system architecture network gate technology is leading.

2+1"In terms of hardware architecture, the system is dual-host + isolated hardware, referred to as 2+1 architecture. Now the mainstream products have also adopted this architectural approach, in which the dual hosts are divided into intranet hosts and extranet hosts, which are used to connect the intranet and extranet on the boundary, which use the commonly used Linux operating system for security applications.

The isolation hardware is used for circuit isolation, low-level write-out, high-level readout, and the intermediate board is a motherboard with an independent clock circuit, and the corresponding content rule control program is set on the motherboard, and a private protocol is used to check and filter the content of the ferry. Both security and performance are relatively high.

Multi-host system architecture gate.

Architecture: The hardware consists of an intranet machine, an arbitration machine, and an extranet machine. Security analysis: The intranet and extranet servers complete the agreement termination, and the arbitrator independently completes the data check. The security is relatively high, and the performance is relatively low.

That's what I know.

At present, the network gate is generally divided into the following types: the standard data network gate used to transmit data; It can support the application of the private gate; The physical link is a one-way import system (commonly known as a one-way shutter).

In addition, from the architecture of the network gate is also divided into three host of three system network gate and two host of 2 + 1 network gate, from my understanding of the domestic network gate manufacturers, the current domestic Shanghai Golden Grid Security can provide all the above mentioned architecture and model of network gate.

Now the network gate is roughly divided into: one-way network gate and two-way network gate, and the two-way network gate can be divided into only Internet access, only data transmission, both Internet access and data transmission.

In terms of architecture, the standard mode (2+1) is adopted, and from what I know, the Cosmoshield network gate is good.

A gateway is also known as an inter-network connector or protocol converter. The gateway implements network interconnection above the network layer and is the most complex network interconnection device, which is only used for the interconnection of two networks with different higher-level protocols. Gateways can be used for both WAN and LAN interconnections.

A gateway is a computer system or device that acts as a translator. Used between two systems with different communication protocols, data formats or languages, or even completely different architectures, the gateway is a translator. Unlike bridges, which simply convey information, gateways repackage the information they receive to fit the needs of the destination system.

Same layer - application layer. The full name of GAP is the safety isolation gate. A safety isolation gate is a kind of network security device that cuts off the link layer connection between networks on the circuit by special hardware with a variety of control functions, and can carry out safe and appropriate application data exchange between networks.

Beijing Digital Star Shield network gate is very good, our company uses this one, the anti-virus ability is particularly strong, it is said that the network gate does not have a file system. Our company's network gate has been used for 8 years and has not broken.

What is a gatekeeper? Reservoir's?

The middle of the security isolation gate is implemented with isolation hardware, and the isolation hardware directly disconnects the network.

On the basis of GAP technology, it is developed according to China's network security needs and related policies, and adopts 2+1 physical architecture combined with private protocols to completely cut off the connection between different network domains to achieve network isolation and real-time information exchange in the true sense.

2+1 means two server systems + one one-way import isolation component. To tell the truth, the network gate is not as good as the optical gate, and the optical gate is the real physical isolation to achieve complete information isolation.

The security isolation and information exchange system is also called the network gate. The earliest batch of domestic manufacturers have good spectrum information.

Protocol divestiture.

Single-lead or bidirectional? Single lead is safe.
