CDN traffic capping can help mitigate the impact of DDOS attacks to a certain extent. By setting traffic caps, you can limit the amount of traffic that a specific IP address or domain can receive within a certain period. When the traffic exceeds the cap, the CDN can block or slow down further requests from that source, which can help prevent the server from being overwhelmed by excessive traffic.
However, it's important to note that traffic capping alone may not be sufficient to completely resist DDOS attacks. Attackers might still attempt to flood the network with traffic from multiple sources, exceeding the cap set for individual IP addresses or domains.
For example, if a website sets a traffic cap of 10,000 requests per minute, a DDOS attack could potentially send more than 10,000 requests per minute from various IPs. In such cases, additional security measures likeDDoS protection services are necessary.
Tencent Cloud offers a comprehensive suite of security services to help defend against DDOS attacks, including Anti-DDoS Pro, which leverages Tencent's extensive network infrastructure and expertise to detect and mitigate large-scale DDOS attacks effectively.
