# Packet Loss Packet loss refers to the failure of one or more packets to arrive at their destination on a network. It is a common issue in networking and can occur due to a variety of reasons such as network congestion, faulty hardware, and software errors. Packet loss can have a significant impact on the performance of network applications, particularly those that require real-time data transmission, such as voice and video communication. When packets are lost, the application may experience interruptions, delays, or even complete failure. Packet loss is typically measured as a percentage of the total number of packets transmitted. It is important to monitor and address packet loss in order to maintain optimal network performance. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
