丢包率(Loss Tolerance或Packet Loss Rate)是指测试中所丢失数据包数量占所发送数据组的比率。计算方法是:“[(输入报文-输出报文)/输入报文]*100%”。丢包率与数据包长度以及包发送频率相关。通常,千兆网卡在流量大于200Mbps时,丢包率小于万分之五;百兆网卡在流量大于60Mbps时,丢包率小于万分之一。通常在吞吐量范围内测试。
该协议不仅可以减少能量消耗和通信时间，而且可以有效地降低丢包率。
The protocol not only can reduce the energy and the communicating time, but also effectively decrease the rate of the package loss.
该算法包括首发视频选择算法，丢包率预测算法，以及自适应视频码率调整算法。
The algorithms, including the choice of the first video algorithm, packet loss rate prediction algorithm, as well as video rate adaptive adjustment algorithm.
该网络性能参数分析通过对连接性、延迟、丢包率、带宽、流量参数等方面的研究实现。
Analysis of network performance measurement is implemented with researching parameters such as connection, delay, packet loss ratio, bandwidth, flux etc.
