传统的网络架构是以网络本身为中心的,用户在使用网络的时候要“追着网跑”。不仅要受到网络接入条件的限制,且接入之后的安全策略和配置内容也和端口绑定,而非基于用户身份——这种网络的安全性越高、配置越复杂,其灵活性也相应越差,为用户的使用带来了种种障碍和不便,削减了企业办公效率。
The traditional network architecture is based on the network itself, when users use the network to “chase the net run.” It is not only limited by the network access conditions, but also the security policies and configuration contents after access are also bound to the ports, not based on the user identity. The higher the security of such networks, the more complicated the configuration and the flexibility The corresponding worse, for the user’s use has brought a variety of obstacles and inconveniences, reducing the efficiency of business offices.
