As already mentioned, the speed should not be relied upon, but the dropped packet counts can be a useful metric.
正如前面提到的，不应该把速度作为可靠的性能指标，但是丢失的数据包数量是有意义的。
In all cases, you are looking for a high level of error packets, retransmissions, or dropped packet transmission, all of which indicate that the network is busy.
在所有情况下，都要寻找比较高的错误数据包、重新传输或丢失数据包传输数量，这些都说明网络忙。
And, because iptrace examines the entire packet from the kernel space, the results can offer lots of dropped packets.
而且，因为iptrace将检查来自内核空间的完整的数据包，所以其结果可能导致丢弃大量的数据包。
If the destination address is not in the routing table, the packet is dropped.
如果其目的地址不在这个路由表里，路由器就将数据包丢弃。
Click on one of the red buttons to send a packet that is dropped by the router because of an invalid address.
点击任何一个红色按钮是发送一个带有非法地址而被路由器丢弃的数据包。
Correcting these dropped packets requires the transmitter to first recognize that the packet was not acknowledged, and then retransmit that packet.
要纠正这种丢失现象，首先需要发送端知道到发送包后并没有得到应答，然后重新传送这个包。
The ECN scheme uses the packet to transfer congestion information, effectively avoids retransmission of dropped packet.
方法利用分组传递拥塞信息，有效地避免了分组的丢失重传。
The simulation results show that the proposed scheme can effectively reduce the average end-to-end delay, mitigate packet dropped ratio, and improve fairness of channel access.
仿真结果表明，提出的机制有效地降低了平均端到端时延和数据丢包率，提高了信道接入公平性。
This time at least 5 seconds for OSPF routing protocol, during the fault the packet will be dropped, most of the applications can accept this level of delay.
对OSPF路由协议，这个时间至少为5秒，期间经过故障节点或链路的流量将会被丢弃，绝大多数的应用可以承受这种程度的延迟。
This time at least 5 seconds for OSPF routing protocol, during the fault the packet will be dropped, most of the applications can accept this level of delay.
对OSPF路由协议，这个时间至少为5秒，期间经过故障节点或链路的流量将会被丢弃，绝大多数的应用可以承受这种程度的延迟。
