Network Security
流量采集传感器
A network device or software agent that passively gathers, aggregates, and forwards network flow records (such as NetFlow, IPFIX, or sFlow) for traffic analysis, anomaly detection, or forensic investigation. See NIST SP 800-137 and IETF RFC 3954.
Quick answer: A network device or software agent that passively gathers, aggregates, and forwards network flow records (such as NetFlow, IPFIX, or sFlow) for traffic analysis, anomaly detection, or forensic investigation. See NIST SP 800-137 and IETF RFC 3954.

Quick answer
A network device or software agent that passively gathers, aggregates, and forwards network flow records (such as NetFlow, IPFIX, or sFlow) for traffic analysis, anomaly detection, or forensic investigation. See NIST SP 800-137 and IETF RFC 3954.
Why it matters
流量采集传感器 matters because it supports clear communication in Network Security contexts for SOC Analysts, Security Engineers, and Incident Responders. It also connects to aviation training and exam language such as CISSP, CompTIA Security+, and CEH.

Operational example
Deploy a flow collector sensor on the core switch to aggregate NetFlow records from all VLANs for monitoring east-west and north-south traffic.
Localized example
在核心交换机上部署流量采集传感器，聚合所有VLAN的NetFlow记录，以监控东西向和南北向流量。
