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.
ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software.
This used to be the most common method of pre-deployment Wi-Fi survey. During an active survey, the wireless adapter is associated with one or several access points to measure round-trip time, throughput rates, packet loss, and retransmissions. Active surveys are used to troubleshoot Wi-Fi networks or to verify performance post-deployment.

Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. . Typical effects include queueing delay, packet loss or the blocking of new connectio
RPL [1] (Routing Protocol for Low-Power and Lossy Networks) is a routing protocol for wireless networks with low power consumption and generally susceptible to packet loss. It is a proactive protocol based on distance vectors and operates on IEEE 802.15.4 , [ 2 ] optimized for multi-hop and many-to-one communication, but also supports one-to ...
In TCP/IP, routers operate within the Internet layer, while the transmission rate is handled by the endpoints at the transport layer. Congestion may be handled only by the transmitter, but since it is known to have happened only after a packet was sent, there must be an echo of the congestion indication by the receiver to the transmitter.
Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput. When a router or switch is configured to use excessively large buffers, even very high-speed networks can become practically unusable for many interactive applications like voice over IP (VoIP), audio streaming , online ...
