# What is Brink Quality Index(BQI)

<br>

BQI is a metric to help understand performance of the applications traversing through Cloudbrink infrastructure. A unique per second quality of receive (RX) and transmit (TX) data is calculated for all sessions going through the Brinkagent. A session that is seeing no packet loss or Cloudbrink recovering all lost packets will typically result in BQI between 80-100% / Excellent.&#x20;

BQI is shown after agent status goes to ‘Running’ state and there is enough data to perform the calculation, typically takes a few seconds after a session is established..&#x20;

Percentage of BQI vs UI representation:&#x20;

80-100 → EXCELLENT (user is receiving best possible QoX over Cloudbrink)&#x20;

60-79 → GOOD (user is receiving next-to-best possible QoX over Cloudbrink)&#x20;

40-59 → AVERAGE (user is receiving optimal experience only, possible because of very high physical network issues such as packet drops)&#x20;

0-39 → POOR (user is receiving poor experience because physical network issues are very high and even with Cloudbrink, network can’t recover from bad conditions)&#x20;
