Advanced Anti-DDoS

Updated on 2024-01-12 GMT+08:00

Advanced Anti-DDoS (AAD) ensures the continuity of important enterprise services. AAD can protect your servers against large volumetric DDoS attacks so your services can be reliable and stable. AAD offers high-defense IP addresses to provide services in place of the original server IP addresses for external systems. The malicious attacks targeting the origin servers can be diverted for scrubbing to ensure the stable running of mission-critical workloads. This service can be used to protect HUAWEI CLOUD, non-HUAWEI CLOUD, and IDC hosts.

NOTE:

If an AAD instance has expired for more than 30 calendar days, AAD will stop forwarding service traffic and the instance will become invalid. If you do not need to use AAD anymore, switch your service traffic from AAD to the origin server 30 calendar days before the expiration date.

  • AAD not deployed

    Without AAD, the origin servers are exposed to the Internet and are prone to paralysis once Distributed Denial-of-Service (DDoS) attacks occur.

    Figure 1 AAD not deployed

  • AAD deployed

    You can connect AAD with your services. The domain name of website service is resolved into high-defense IP address, and the service IP address of the non-web service is changed to the high-defense IP address. All public network traffic is diverted to the high-defense IP address, and therefore user services on the origin servers are protected against DDoS attacks.

    Figure 2 AAD deployed

AAD Mechanism

The AAD service uses the high-defense IP address to proxy services for origin servers. All public network traffic is diverted to the high-defense IP address, and therefore user services on the origin servers are protected against DDoS attacks. The following figure illustrates the mechanism of AAD traffic diversion and forwarding.

  • Customer

    Customer who accesses the origin server

  • Origin server IP address

    A public IP address used by the origin server (also known as the IP address that is protected against exposures)

  • High-defense IP address

    An IP address used to provide services for customers in place of the origin server IP address

  • Back-to-origin IP address

    An IP address used to communicate with the origin server IP address in place of the customer IP address in the AAD data center

AAD provides defense against a wide range of network-, and application-layer DDoS attacks, including SYN flood, UDP flood, ACK flood, ICMP flood, DNS query flood, NTP reply flood, and CC attacks.

Service Architecture

Employing multi-layer filtering and protection technologies, such as layered defense and distributed scrubbing, the AAD service can effectively detect and filter out attack traffic. Figure 3 illustrates the network topology of the AAD service.
