====== FastPCRF (BRAS integration by RADIUS) ======
{{indexmenu_n>2}}

PCRF provides proxying requests from fastDPI to the Radius server.
It is a part of the standard Stingray Service Gateway installation package, but if necessary, it can be used as a dedicated server.
===== Hardware Recommendations =====

In order to run PCRF you can use the following hardware or virtual machines matching the following characteristics:
  - CPU 2.5 GHz, 1 pcs
  - RAM 512 MB - 1 GB
  - HDD 50 GB - 250 GB
  - Operating system Cent OS 8.5, [[en:veos:installation|VEOS]]
  - NIC ranging from 10 Mb/s

===== Installation =====
  - Install the Network Time Protocol daemon <code>yum install chrony -y
systemctl restart chronyd
timedatectl</code> :!: When entering the ''timedatectl'' command, the ''System clock synchronized'' parameter must be set to ''yes''
  - Add vasexperts repository <code>rpm --import http://vasexperts.ru/centos/RPM-GPG-KEY-vasexperts.ru
rpm -Uvh http://vasexperts.ru/centos/6/x86_64/vasexperts-repo-2-1.noarch.rpm</code>
  - Install the fastPCRF <code>yum install fastpcrf</code>
  - Make sure the service is running <code>service fastpcrf start</code>
  - Сonfigure fastpcrf service to run at startup<code>systemctl enable fastpcrf</code>
  - Open firewall ports in order to access the fastPCRF and Radius servers<code>firewall-cmd --permanent --zone=public --add-port=22/tcp
firewall-cmd --permanent --zone=public --add-port=3799/udp
firewall-cmd --permanent --zone=public --add-port=29002/tcp
</code>
and restart firewall for the rules to take effect <code>firewall-cmd --reload</code>
  - Disable selinux ((temporary solution))<code>setenforce 0
vi /etc/selinux/config
SELINUX=disabled</code>
 
 
===== Installation of the fdpi_cli and fdpi_ctrl utilities on the PCRF server =====

You can get these utilities from the server where ''fastDPI'' is installed.\\
The utility files are located in ''/usr/sbin/''.
  - Copy the utilities to the home directory <code>
cp /usr/sbin/fdpi_cli /home/vasexpertsmnt
cp /usr/sbin/fdpi_ctrl /home/vasexpertsmnt
</code>
  - Move these files to the server where ''fastPCRF'' is installed, to ''/home/vasexpertsmnt''

How to use the utility:\\
<code>
fdpi_cli -r 1.1.1.1 dpi config get trace_ip 
fdpi_cli -r 2.2.2.2 pcrf config get verbose
fdpi_ctrl -r 1.1.1.1:29000 list all --bind
</code>
Server address – ''1.1.1.1'' where the ''fastDPI'' module is installed.\\
Server address – ''2.2.2.2'' where the ''fastPCRF'' module is installed.
