Network devices typically include Load Balancer devices such as routers and firewalls that maintain the network usefully. When the network is attacked by the outside world, the router is the first to die, but other machines are not dead. Dead routers will recover after restarting, and the launch speed will be faster than before, and nothing will be lost. If another server dies, the data in between is lost, and restarting the server is a lengthy process. In particular, one company used a Load Balancer device, so that when one router was attacked and crashed, the other would immediately work. And then minimized the DDoS attacks.

(2)Filter unnecessary services and ports

This refers to filtering out false IP on the router, and only opening the service port is a common practice in today's high-defense servers, such as WWW servers only opening 80 and closing all other ports or blocking strategies on the firewall.
