VPN Features In practical applications, what kind of VPN do users need? In general, an efficient and successful VPN should have the following characteristics:
First, Security
Although there are many technologies and ways to realize VPN, all VPNs should ensure the speciality and security of data transmission through public network platform. Establishing a logical, point-to-point connection on a non-connection-oriented public IP network is called establishing a tunnel. Encryption technology can be used to encrypt the data transmitted through the tunnel to ensure that the data is only sent to the designated sender and receiver. understand, thereby ensuring the privacy and security of the data. In terms of security, since VPN is directly built on the public network, the implementation is simple, convenient and flexible, but at the same time its security problems are more prominent.
Enterprises must ensure that data transmitted over their VPNs cannot be spied on and tampered with by attackers, and to prevent unauthorized users from accessing network resources or private information. Extranet VPN expands the enterprise network to partners and customers, puts forward higher requirements for security, and ensures the security of data. https://www.spotoclub.com/.
Second, Quality of Service Assurance (QOS)
The VPN network should provide different levels of service quality assurance for enterprise data. Different users and services have different requirements for service quality assurance. For example, for mobile office users, providing a wide range of connections and coverage is a major factor in ensuring VPN services; while for private line VPN networks with many branches, interactive internal enterprise network applications require the network to provide good stability; Other applications (such as video, etc.) put forward more specific requirements on the network, such as network delay and bit error rate. All of the above network applications require the network to provide different levels of service quality as needed. In terms of network optimization, another important requirement for building a VPN is to make full and effective use of limited WAN resources to provide reliable bandwidth for important data. The uncertainty of WAN traffic makes its bandwidth utilization very low, causing network congestion during traffic peaks, resulting in network bottlenecks, so that data with high real-time requirements cannot be sent in time; And when the traffic is low, a lot of network bandwidth is idle. Through traffic prediction and traffic control policies, QOS can allocate bandwidth resources according to priorities and implement bandwidth management, so that various types of data can be sent in sequence and prevent congestion.
Third, Scalability and Flexibility
The VPN must be able to support any type of data flow through the Intranet and Extranet, facilitate the addition of new nodes, support multiple types of transmission media, and meet the requirements for high-quality transmission and increased bandwidth for new applications such as simultaneous transmission of voice, images, and data, which requires the VPN to be scalable and flexible.
Fourth, Manageability
It should be easy to manage and maintain from the user’s perspective and the operator’s perspective. In terms of VPN management, VPN requires enterprises to seamlessly extend their network management functions from the local area network to the public network, and even customers and partners.
While some minor network management tasks can be left to service providers, enterprises still need to perform many network management tasks by themselves. Therefore, a perfect VPN management system is essential. The goal of VPN management is to reduce network risks and have the advantages of high scalability, economy, and high reliability. In fact, VPN management mainly includes security management, device management, configuration management, and access control list management. The above four points are the main features that an efficient and successful VPN should have. If you have any questions, please consult SPOTO. read more: can i get ccnp without ccna
