我们的DDoS 防护服务如何工作

Flood Shield DDoS deflection technology is deployed on CDNetworks’ distributed Points-of-Presence (PoPs). It is a cloud-based “always-on” mitigation service with virtually unlimited capacity. It does not require sophisticated deployments and changes to customers’ networks and provides transparent scaling automation. Flood Shield is provided either via a simple DNS change, typically to protect websites, HTTP/S traffic and entire network infrastructures, including multiple domains, servers, and protocols. With the customer traffic routed through CDNetworks’ PoPs, DDoS attacks hit the CDNetworks infrastructure rather than the customers’ servers and networks. CDNetworks’ PoPs detect and deflect both application-layer attacks (L7) and all known types of network-layer attacks (L3/L4).
