What is a common indicator of connectivity issues during verification testing?

High packet loss rates serve as a significant indicator of connectivity issues during verification testing. When packets are lost during transmission, it suggests that there may be problems with the network's reliability and performance. This loss can occur due to various factors, such as network congestion, poor signal quality, or faulty hardware, all of which can severely disrupt communication between devices.

In contrast, low bandwidth usage usually suggests that the network is not being fully utilized, which may not directly indicate a connectivity issue. Frequent disconnections indicate that there are interruptions in the connection, but they may not specifically relate to packet loss as a direct measure of ongoing transmission problems. Minimal latency generally reflects a healthy network condition, as low latency indicates that data packets are being transmitted quickly without delay. High levels of packet loss, however, are universally recognized as a critical measure indicating that there are severe issues that need to be addressed for reliable network performance.
