Simple analysis of the three important requirements for remote network connections

The continuous emergence and upgrading of online games, online videos and various shopping applications have put higher and higher requirements on the network, which not only needs basic connectivity and sufficient performance, but also has the necessary security and intelligence. Next, I will tell you about the important requirements for remote network connections.

Remote network connection

1. Connectivity requirements

Connectivity is a basic function of computer networks. Computer networks connect institutions, personnel, and facilities scattered across the country. This is a connection method that should be selected based on the time of use, location, required bandwidth, and cost.

For example, using a mobile phone APP to control the operation of smart home appliances is a simple operation; there are also operations such as connecting to the corporate network when working at home or on the road; data transmission between branches and campuses of large/medium-sized enterprises, etc.

However, the reliability of remote connections is relatively low and prone to various types of failures. At this time, we need to enhance its configuration or add alternative connection methods.

2. Security requirements

Nowadays, any enterprise network pays more and more attention to security, which is mainly reflected in the following aspects: First, since institutions scattered across the country need to be connected to each other through a wide area network, the enterprise's data must be transmitted across the wide area network, so the security of the wide area transmission of data must be guaranteed; secondly, an organization's data processing and storage devices are actually located in various nodes or sites, so the security of the nodes or sites themselves must also be guaranteed; finally, usually every enterprise organization will have some people who are on business trips or working from home, and these people must be allowed to access the internal network anytime and anywhere, so it is also very important to ensure user access security.

Since remote connections are beyond the management scope of the organization itself and are built on the networks and facilities of other organizations, they face more security risks. Therefore, the network must be able to confirm the identity of the accessor, prevent the security of remotely transmitted data, hide detailed information inside the network, reduce system vulnerabilities, and prevent potential attack risks.

3. Optimization requirements

With the increasing richness of network applications, various application data coexist on the same network, and different types of data have different requirements for network services. Therefore, the network must be able to identify different application types, users and data flows, and provide them with appropriate resources.

Therefore, a typical enterprise network should include these aspects: network control; network management; file transfer; network storage; control of voice, video, application data and related applications; remote maintenance and operation; electronic transactions and ERP (Enterprise Resource Planning); and Internet access.

Remote network connection

Finally, to summarize, remote connections require sufficient performance and ensure the convenience of mobile access; the security requirements of remote connections are reflected in aspects such as wide area network transmission security, node site security and access security; the network should provide differentiated services for different users, application types, and data flows, and can further guarantee the network resources they obtain and the mechanisms to provide the performance they require.
