PAN firewall is having 2 planes ( data-plane and mgmt-plane) to perform all tasks in a organize manner.

For example:


-- it takes care about all daemons running in the firewall i.e authd, mgmt-server, dev-server etc.

-- Running dynamic routing protocols i.e OSPF, BGP

--- IPSec key management

-- firewall GUI.

Data-plane CPU:

--  Handles traffic, passing across the PAN firewall.

--- Physical interface management.

--- Maintaning active routing table for traffic.

This diagram of the PA architecture tries to capture the separation of data plane packet processing and management plane control system processing.


See the tech brief on Content ID for a fuller discussion on the processing modes in the PA firewall.
