Junos OS Flow-Based and Packet-Based Processing Library for Security Devices
Junos OS includes a wide range of packet-based filtering, class-of-service (CoS) classifiers, and traffic-shaping features as well as a rich, extensive set of flow-based security features including policies, screens, network address translation (NAT), and other flow-based services. Traffic that enters and exits security devices is processed according to features you configure, such as packet filters, security policies, and screens.
This page links you to feature guides that provide conceptual information for flow-based and packet-based processing. They also provide related configuration examples and reference information.
