In software release 4.7 Cambium introduces Deep Packet Inspection (DPI) feature. This feature is the extension for ePMP Smart QoS feature. DPI can be enabled on AP and SM. So Smart QoS can be set on an application type basis. The feature will be supported by AC series radios: PTP550, ePMP3000, ePMP 3000L, ePMP Force 300-13/16/19/19R/25/CSM except L-indexed radios. It will be absent in CnVision and N series radios.
Deep Packet Inspection is an advanced method which provides a robust mechanism for executing network packet inspection and prioritizing. It is able to examine the full contents of packets as they pass through Cambium Access Point (AP) and Subscriber Module (SM). Then it takes actions immediately according to priority settings. The main aim is to make user critical applications traffic to be transmitted with priority without the need to mark application traffic at network edges. It allows achieving a high output by the ability of DPI technology to classify all traffic by priorities, providing wider bandwidth to certain applications. Availability and high quality of service are the main indicators of the provider’s performance. Such problems as slow pages’ downloads and stuttering sound during video calls are very annoying for users. These issues can be improved by managing QoS with the DPI function.
Station in AP and SM mode manages priority of traffic flow to be transmitted over the wireless interface. Deep Packet Inspection works with the Traffic Priority function simultaneously. Packet scheduler processes DPI Traffic Priority rules before Traffic Priority rules. DPI priority rules should be configured on AP and SM for bi-directional priority.
License key is required for AP only and the feature can be enabled without License Key on SMs. A license key can be obtained on Cambium Networks web site with entitlement purchased from a local distributor. The license is per year. It uses the same mechanism as licensing to unlock a country in ETSI region or to get unlimited elevated radios connection.
GUI > Tools > License management
STA does not need a license that unlocks DPI usage. It is available by default.
Configuration > Network > Deep Packet Inspection
Then save configuration. Now it is available to observe users traffic statistics by used applications in Monitor > DPI section.
Traffic statistics can be represented as “Aggregated Applications Traffic” for each application group and “Overall applications usage” for each application . Both views are shown on screenshots below. Also graphical donut can be switched to show downlink or uplink statistics.
GUI > Monitor > DPI
To configure priority go to Configuration > Quality of Service. Set DPI Traffic Priority Enabled and configure priority rules.

Current screenshot represents configured rules for applications and applications groups with different priorities.

|Smart QoS Feature State||Locked||No valid license applied|
|Unlocked||Valid license is applied, and feature is unlocked|
|DPI Traffic Priority||Disabled||Modifications to the DPI Traffic Priority are not allowed and rules are not enforced.|
|Enabled||Modifications to the DPI Traffic Priority are allowed and rules are enforced.|
|Type||Application group||The rule applies traffic priority to all applications in the group.|
|Application||the rule applies to a single application.|
|Target ID||-||Defines the application group name or the name of the single application.|
|Priority||Low||lowest traffic priority|
|High||high traffic priority|
|Voice||the highest priority for the most critical applications|
By default, all traffic passed over the air interface is low priority. The rules included in the table are enforced starting with the first row of the table.
DPI traffic priority rules are processed before traffic priority rules based on CoS and DSCP.
Each classification increases CPU utilization and may lead to system performance degradation. Careful network traffic planning is required to efficiently use the device processor.
DPI feature provides traffic inspection statistics independent of whether traffic priority is enabled or not. So administrator can examine all applications traffic and not only prioritized one.
The table below describes applications in each application group. The list of applications will be extended in next software releases.
