What is intranet penetration? In the Internet era, “intranet penetration” is a term with a high frequency, but most users are not clear about this concept. Before we understand the highlights of HOREB personal cloud intranet penetration function, let’s talk about what intranet penetration is: intranet is a local area network or office network established within a company or family, which can realize resource sharing among multiple computers, including equipment, data, data, etc.
Compared with the internal network, the external network is connected with other network systems through a gateway (optical cat and router). This network system is called the external network. It is common that the Internet we use in daily life. Generally speaking, in the absence of a fixed public IP address, the external network device cannot directly access the internal network device and the internal network penetration technology, as the name implies, is to enable the external network device to find the device in the internal network, So as to realize data communication at any time and anywhere.
The principle of intranet penetration: Intranet penetration is also called NAT penetration, that is, when the computer is in the LAN, the connection communication required for the connection between the external network and the node of the computer in the intranet can be divided into three ways. The first way is the port forwarding of the dynamic public IP. This method needs to first obtain the public dynamic IP from the operator, and then set the port mapping on the router to establish the connection between the external network and the internal network.
The disadvantages of this method are: 1) It is difficult to obtain dynamic IP; 2) Manually configuring port mapping is cumbersome; 3) The second method with security risks is the transfer and forwarding method. This method transfers data between the external network and the internal network through one or more transfer servers, so as to establish a connection. Although this method does not require public network IP, the transfer needs to consume bandwidth, and the cost of bandwidth is high, so there is usually the problem of network speed restriction.
The third method is point-to-point NAT penetration technology. It uses UDP protocol to build NAT address translation table adaptively to realize point-to-point machine direct communication. This method does not need public IP, nor does it need to use the third party relay HOREB personal cloud. This method is adopted, which is not only small delay, high bandwidth, but also very simple and convenient to use.
The functional highlights of HOREB personal cloud intranet penetration: 1 (in most cases) can realize point-to-point direct connection, with fast speed and small delay; 2 (In extreme cases) If the direct connection fails, it will automatically switch to the forwarding mode; 3 Full-process encryption, even when working in the forwarding mode, the data will not be disclosed.
