-====== Policing by session and overriding traffic classes ======
-{{indexmenu_n>4}}
-Policing by session and traffic class override is implemented using connection 18 services for Subscriber and Virtual Channel (vChannel).
-The service extends the possibilities of policing by determining the traffic rate for a particular session. It is also possible to override the traffic class for a specific Subscriber or Virtual Channel.
-Recall that global traffic class markup is described in [[en:dpi:dpi_options:opt_priority:start|]]. \\
-Important: Directional priority overrides protocol priority, so if traffic already has [[en:dpi:dpi_options:opt_priority:priority_config_as:start|]], this service will not override the traffic class.
-===== SSG Configuration =====
-The service **requires additional RAM** (compared to standard requirements), which is reserved by a setting in **/etc/dpi/fastdpi.conf**:
-<code bash>support_service_18=1 </code>
-To apply the settings, you must restart the service: **service fastdpi restart**
-===== Setting up and managing the service =====
-==== Configuring Policing by Session ====
-It is necessary to create a file describing the speed for a particular protocol and convert it using the lst2tbf utility.
-  * rate - session polysing rate for outgoing traffic
-  * inbound.rate - polysing rate by session for incoming traffic
-  * burst - short-term excess rate
-  * inbound.burst - short-term excess inbound.rate
-<code bash>
-speedtest tbf rate 16mbit inbound.rate 16mbit
-bittorrent tbf rate 8Mbit
-TCP Unknown tbf rate 8Mbit burst 1Mbit inbound.rate 8Mbit inbound.burst 1Mbit
-cat tbf_prof_1.txt|lst2tbf /tmp/tbf_prof_1.tbf
-</code>
-Reverse conversion tbf2lst /tmp/tbf_prof_1.tbf
-==== Configuring traffic class overrides ====
-It is necessary to create a file describing traffic classes using the lst2dscp utility.
-<note important>[[dpi:dpi_options:opt_statistics:statistics_info:start|Full list of protocols.]]\\
-The DSCP value is specified [[dpi:dpi_options:opt_priority:dscp_table:start|in numeric (10-, 16-, or 8-character) format or with a text abbreviation.]]</note>
-The key word means:
-  * drop - packets should not be transmitted further (they should be discarded)\\
-  * keep - the priority value should not be changed, i.e. keep its current value (usually 0).\\
-  * default - means "for all other protocols" and it allows to significantly simplify and shorten the process of creating a configuration file
-File creation procedure ''dscp_prof_1.dscp'':
-<code bash>
-speedtest cs1
-default keep
-cat dscp_prof_1.txt|lst2dscp /tmp/dscp_prof_1.dscp
-</code>
-Reverse conversion: ''dscp2lst /tmp/dscp_prof_1.tbf''
-==== Creating a service profile ====
-<code bash>
-fdpi_ctrl load profile --service 18  --profile.name test_dscp --profile.json '{ "dscp" : "/tmp/dscp_prof_1.dscp", "tbf" : "/tmp/tbf_prof_1.tbf" }'
-</code>
-<note important>You should always specify the path to both files, even if you only want to set session polyscing or only override traffic classes. Specify an empty file if no customization is required.</note>
-==== Connecting a service profile ====
-For the subscriber:
-<code bash>
-fdpi_ctrl load --service 18  --profile.name test_dscp --ip 10.10.10.10
-fdpi_ctrl load --service 18  --profile.name test_dscp --login DEMO
-</code>
-For a virtual channel (vChannel):
-<code bash>
-fdpi_ctrl load --service 18  --profile.name test_dscp --vchannel 1
-</code>
-==== Deleting a service profile ====
-For the subscriber:
-<code bash>
-fdpi_ctrl del --service 18  --profile.name test_dscp --ip 10.10.10.10
-fdpi_ctrl del --service 18  --profile.name test_dscp --login DEMO
-</code>
-For a virtual channel (vChannel):
-<code bash>
-fdpi_ctrl del --service 18  --profile.name test_dscp --vchannel 1
-</code>
-==== Display of information on service profiles ====
-Get a list with connected 18 service
-<code bash>
-fdpi_ctrl list all --service 18
-</code>
-Get information on a specific IP/LOGIN/vChannel
-<code bash>
-fdpi_ctrl list --service 18 --ip 192.168.0.1
-fdpi_ctrl list --service 18 --login DEMO
-fdpi_ctrl list --service 18 --vchannel 1
-</code>
