Terms and Acronyms

• active flow monitoring—Technique to lawfully intercept and observe specified data network traffic on an active router participating in the network.
• Adaptive Services PIC—Advanced PIC that handles active flow monitoring, Network Address Translation (NAT), stateful firewall, and intrusion detection functions. For more information on the Adaptive Services PIC, see the JUNOS Internet Software Services Interfaces Configuration Guide.
• cflowd—Process that captures flow information from network traffic and exports this data into summary tables. Once captured, flow data can be analyzed as needed. For more information about cflowd, see http://www.caida.org.
• ES PIC—PIC that handles encryption and security services (such as IPSec).
• flow collector interface—Converted Monitoring Services II PIC that processes multiple cflowd records into compressed ASCII data files and exports these files to a File Transfer Protocol (FTP) server.
• Monitoring Services PIC—Original PIC that handles passive and active flow monitoring functions.
• Monitoring Services II PIC—Advanced PIC that handles passive flow monitoring functions.
• passive flow monitoring—Technique to lawfully intercept and observe specified data network traffic on a passive flow monitoring station not participating in the network.
