Definition of Terms

The following are terms used in SCI.

Term Definition
User Traffic
User Traffic Traffic volume, which is transmitted and received in IEEE 802.11 MAC Service Data Unit (MSDU) data frames. This includes all unicast, multicast and broadcast traffic. User Traffic = Rx User + Tx User

Rx User

Traffic volume, which is received by AP (Access Point) in IEEE 802.11 MAC Service Data Unit (MSDU) data frames. This includes all unicast, multicast and broadcast traffic.
Tx User Traffic volume, which is transmitted by AP (Access Point) in IEEE 802.11 MAC Service Data Unit (MSDU) data frames. This includes all unicast, multicast and broadcast traffic
Management Traffic
Management Traffic Traffic volume, which is transmitted and received in IEEE 802.11 control and management frames. This includes all unicast, multicast and broadcast traffic. Abbreviations Mgmt or Mgt are frequently used in the user interface. Mgmt Traffic = Rx Mgmt + Tx Mgmt

Rx Mgmt

Traffic volume, which is received by AP (Access Point) in IEEE 802.11 control and management frames. This includes all unicast, multicast and broadcast traffic.

Tx Mgmt

Traffic volume, which is transmitted by AP (Access Point) in IEEE 802.11 control and management frames. This includes all unicast, multicast and broadcast traffic
Total Traffic
Total Traffic

Is the sum of the user traffic and management traffic.

Rx Total Is the sum of the Rx user traffic and management traffic.
Tx Total Is the sum of the Tx user traffic and management traffic.
Relationship between various traffic metrics
  • Total Traffic = User Traffic + Management Traffic = Rx Total + Tx Total
  • Rx Total = Rx User + Rx Managemet
  • Tx Total = Tx User + Tx Managemet
  • User Traffic = Rx User + Tx User
  • Managemet Traffic = Rx Managemet + Tx Managemet
Average Traffic Rate

Traffic volume divided by the selected time period, displayed in bits per second. For example, if the traffic volume for a 15 minutes period is 100GB, the average traffic rate is 889Mbps.

Unique Client
A Wi-Fi client, uniquely identified by its MAC address.
Note: All Radios unique count will not be larger than the sum of the 2.4GHz and 5GHz radios. This is because a Wi-Fi client could connect to both radios within the selected time granularity, and All Radios unique count will consider this client as a single count.
Session In SCI, session refers to IEEE 802.11 session. This is an OSI Layer 2 session that is established when a Wi-Fi client associates to an access point and it ends when the client disassociates from the access point.
Note: This is NOT the same as OSI Layer 7 application layer sessions, like a HTTP session, telnet session, etc. More often than not, a single IEEE 802.11 session cannot support multiple application layer sessions, and the creation and termination of IEEE 802 sessions are often transparent to the user at the application layer.
