| Term | Description |
| packet loss | Packet loss refers to the percentage of packets sent that will be lost (out of 100%) in a data transmission. As with other metrics, carriers define a benchmark amount of packet loss for their network in a Service Level Agreement (SLA). Packet loss is an indication of congestion on a network, so the level of packet loss defined by a carrier's SLA indicates the amount of congestion the carrier expects on their network. |
