Packet Loss

Packet Loss refers to the failure of data packets, transmitted over an IP network, to arrive at their

destination. Packet Loss is described as a percentage of the total packets transmitted.

Network congestion within a LAN or WAN, faulty or incorrectly configured network equipment or faulty

cabling are among the many causes of Packet Loss.

Packet Loss affects the quality of:

● Video – frozen images, decreased frame rate, flickering, tiling, distortion, smearing, loss of lip sync

● Audio – drop-outs, chirping, audio distortion

● Content – frozen images, blurring, distortion, slow screen refresh rate
