Flow Monitoring 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 Services Interfaces Configuration Guide.

cflowd

Version 5 and version 8 flow monitoring 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.

content destination

A recipient of monitored packets sent by a DTCP or dynamic flow capture-enabled monitoring station.

control source

A dynamic flow capture client that wants to monitor electronic data or voice transfer over the network. The control source sends filter requests to the dynamic flow capture-enabled monitoring station by using DTCP.

dynamic flow capture

Technique that allows DTCP-enabled control sources to send specified filtering criteria in real time to a monitoring station. The monitoring station passively monitors the specified traffic flows on demand and sends the captured packets to content destinations.

DTCP (Dynamic Tasking Control Protocol)

Protocol used to specify filtering criteria in a dynamic flow capture environment.

ES PIC

PIC that handles encryption and security services (such as IP Security [IPSec]).

flow collector interface

Converted Monitoring Services II PIC that processes multiple flow records into compressed ASCII data files and exports these files to an 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.

Monitoring Services III PIC

Advanced PIC that handles dynamic flow capture functions.

MultiServices 100 PIC

Also referred to as MultiServices PIC Type 1. Advanced PIC that handles active flow capture functions.

MultiServices 400 PIC

Also referred to as MultiServices PIC Type 2. Advanced PIC that handles active flow capture functions.

MultiServices 500 PIC

Also referred to as MultiServices PIC Type 3. Advanced PIC that handles active flow capture 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.
