并对这种攻击提出了基于TCP连接包丢失率检测的防范措施。
Then, some countermeasures including the detection of TCP packets dropping rate are proposed to defend against this attack.
网络能提供较好的服务质量(包丢失率和包传输延迟)并兼容多种业务。
The network could provide good quality of service (in packet loss rate and the packet transfer delay) and be compatible with a variety of services.
基于一定的数据包丢失率和恒定时延，系统被建模为由结构事件率约束的异步动态切换系统。
Based on fixed data packet dropout rates and constant time-delay, the NCS is modeled as an asynchronous dynamical-switched system constrained by configuration event rates.
主要表现为在高速网络环境下，现有的协议算法不能保证低的包丢失率和低的时延及时延抖动等服务质量需求。
It is mainly exhibited as in the high bandwidth network environment, the current protocol algorithms can't guarantee nicer service quality of low packet loss rate, RTT and dithering of RTT.
然而现有的互联网络建立在传输非实时数据的基础上，在延迟、抖动和包丢失率等方面，缺乏对实时通信的良好支持。
However, since the current Internet is not built for real-time data transition, support is lacking in the Internet to meet delay, jitter and packet loss requirements for real-time traffic.
如果主机是已知的，但是用户抱怨这个主机本身或它上面运行的应用程序没有响应，那么使用ping并查看数据包丢失率是否为0%(见清单6)。
If a host is known but you find that users are complaining that the host itself or an application running on it isn't responding, use ping and look for 0% packet loss (see Listing 6).
在有线网络中随机比特差错率可以忽略，拥塞主要由包丢失造成。
In a wired network, random bit error rate may be neglected and the congestion result from packets loss.
