How does HiNet differentiate between legitimate traffic and malicious traffic during a DDoS attack?

HiNet uses a combination of techniques to differentiate traffic. These include analyzing traffic patterns, identifying known malicious IP addresses, employing rate limiting (restricting the number of requests from a single source), and using behavioral analysis to detect anomalous activity. Advanced techniques like CAPTCHAs and challenge-response systems can also help distinguish between humans and bots.
