As Usually, the basic network of government departments is divided into government intranet, government special network and government extranet. The government intranet is a secret-related network, physically isolated from the public network. The government special network is a non-secret internal office network, and the government external network is a special business network for government services abroad, which is logically separated from the Internet through firewalls. In the use of government network, it is often necessary to control the access of the network by multi-level authority. Access to the network is not allowed at will. At the same time, due to the diversity of network equipment interfaces, it is necessary to support the access of PDH, SDH and ETH interfaces at the same time.
