SmartCell Insight Report on Actual Traffic Rate for APs and Client
SmartZone (SZ) reports the total traffic statistics at an interval of every three minutes or 15 minutes to SmartCell Insight (SCI).
For traffic rate calculation, SCI divides the total traffic by time. But, this is not sufficient to accurately calculate airtime efficiency, as APs may not be sending or receiving the traffic all the time in the 15 minute interval. In other words, the SCI reporting of traffic rate needs to be across two dimensions:
- Traffic Over Time: This is the current metric, and effectively captures how much traffic was sent or received over a period of time. The goal of this metric is to capture traffic, so that network operators can identify how much the network is being used in a time period.
- Traffic Efficiency: This is the new metric, and effectively captures how much airtime was required to send receive traffic over time. The goal of this metric is to capture traffic efficiency, so that network operators can identify network performance in a time period.
To accomplish the efficiency calculation, information about both traffic and airtime usage (Tx,Rx, and busy), are measured as counters in a reporting interval. For SCI to do this, SZ will send the following information to SCI at the AP level.
- Total traffic Uplink and downlink time
- Total Tx Time: How much time did the AP spend transmitting traffic
- Total Rx Time: How much time did the AP spend receiving traffic for the AP's basic service set identifier (BSSIDs)
- Other Rx Time: How much time did the AP spend receiving broadcast traffic and traffic for other BSSIDs
NOTEThe reason for this metric is to distinguish between AP traffic and environmental traffic, where environmental traffic does affect airtime availability, but is not incorporated into the traffic efficiency calculation.
- Total Tx/Rx Time: How much time did the AP spend receiving and sending traffic in total for its BSSIDs
- Idle Time: How much time did the AP spend idle
SZ will send the following information to SCI at the Client level.
- Total traffic Uplink and downlink time
- Total Tx Time: How much time did the client spend transmitting traffic
- Total Rx Time: How much time did the client spend receiving traffic for the AP's basic service set identifier (BSSIDs)
- Total Tx/Rx Time: How much time did the client spend receiving and sending traffic in total for its BSSIDs
