Packet loss
 | This article includes a list of general references, but it lacks sufficient corresponding inline citations. (February 2013) |
Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks,[1][2] or network congestion.[3]: 36 Packet loss is measured as a percentage of packets lost with respect to packets sent.
The Transmission Control Protocol (TCP) detects packet loss and performs retransmissions to ensure reliable messaging. Packet loss in a TCP connection is also used to avoid congestion and thus produces an intentionally reduced throughput for the connection.
In real-time applications like streaming media or online games, packet loss can affect a user's quality of experience (QoE).
