DoS attacks

A Denial of Service (DoS) attack disables users from connecting to the server. DoS attacks aim to occupy excess resources by sending a large number of connection requests. As a result, authorized users cannot receive responses from the server.

URPF（Unicast Reverse Path Forwarding） is usually used on a single device to defend against such attacks. URPF searches the outbound interface in the FIB table according to the source IP address of the packet, and checks whether the outbound interface matches the source interface of the packet. If the source IP address does not match the outbound interface of the packet, the packet is discarded. This prevents IP spoofing attacks, especially DoS attacks with bogus source IP address.

@Mr.Jack hello, actually, Huawei provides a physical equipment aim on the anti-ddos.
It provides quite a few defense policies.
