Packet loss rate
The packet loss rate ( english packet loss rate , short PLR), is in communication engineering a measure of the quality of a transmission channel . The packet loss rate, which is usually given as a percentage, indicates how many packets of a data stream between a sender and receiver were lost during transmission, i.e. could not be received. It is calculated from the ratio of the number of lost data packets to the number of data packets sent, e.g. B. IP packets :
with n … = number of packages.
The cause of the loss can be damaged transmission lines or e.g. B. be an interferer on the same transmission frequency .
For a good connection, this error value should be as small as possible, ideally zero. According to ITU G.114, packet loss rates of up to 5% are still considered acceptable for IP telephony .
