Will affect the performance of VPN VPN products can accommodate computers and network capacity, such as the establishment of VPN tunnels while the number of users simultaneously access VPN and so on. If the VPN products can not meet the needs of enterprise performance, it is difficult to carry business operations; and if used too much high-end VPN products, but also a waste of resources. Therefore, in the performance choice should be based on the actual situation on-demand product compared to manufacturers. Good VPN product should enable the user according to their own needs, the application for the distribution of different priority levels of different ratios of bandwidth. At the same time the bandwidth allocation function was good or bad intelligence is becoming a competition between the manufacturers of a new technology - when the lines are idle, applications are free transmission; the event of a line is busy or congested, the system first to ensure that priority the application of high level interference, protect the normal development of key business enterprises.
