Government

 Nowadays, government network operators divide many virtual LANs, private VLANs (PVLANs), and even many Virtual Routing and Forwarding (VRF) instances throughout the campus. In the employee's office area, the entire campus network is filled with various types of tenants handling different applications, such as IP-enabled HVAC units, telephone, video, and building control. In addition, different types of traffic need to correspond to different networks, such as office traffic and key business traffic. Each tenant can handle different applications. Finally, these policies can be deployed separately or deployed as a whole.
