In the operator industry, traffic replication/convergence is a key link in network operation and maintenance, security monitoring, and business optimization. Typical application scenarios include network monitoring and security protection. By replicating the traffic of key links to multiple security devices (such as intrusion detection systems, security audits, etc.), multi-layer protection and real-time monitoring can be achieved. Meanwhile, the traffic convergence function can centralize the processing of scattered traffic, facilitating unified analysis of network performance and optimization of resource allocation.
