packet loss ratio meaning in Chinese
丢包率
Examples
- We introduce two thresholds of the packet loss ratio to divide the network load condition into three status : congest , normal , idle
通过两个门限值c 、 _ ，将网络的负载状况分为拥塞、适中、空闲三种状态，进一步减小发送速率的振荡频率。 - Sending rate could be adjusted according to the rate scheme in the end host . simulations showed that etcc can adjust sending rate smoothly , decrease delay and packet loss ratio while maintaining good tcp - friendliness
仿真实验表明etcc机制可以在保证tcp友好的前提下平滑调节多媒体流的发送速率，同时降低网络的延时和丢包率。 - The main contributions of the thesis are : ( 1 ) we present an end - to - end transport architecture using the rtp / udp / ip protocol stack and employ an efficient and robust packetization algorithm for mpeg - 4 video bit - streams at the sync layer for internet transport . ( 2 ) we study the congestion control mechanism based on aimd algorithm , and make improvement in order to reduce the oscillation of transimition rate due to tremendous contrast of packet loss ratio caused by dynamical change of the network load
论文的主要贡献在于：提出了基于rtp的mpeg - 4视频传输模型并充分利用mpeg - 4的videoobjectplane ( vop )特性，采用适用于mpeg - 4视频传输的rw载荷格式及组包算法，同时具有传输的高效性和丢包的鲁棒性。 - We chose suitable tcp throughput model to estimate the available bandwidth correctly , using the estimated round trip time and packet loss ratio for the next time interval as parameters of the model to achive the accuracy of estimated network bandwidth . as the observed losses and round trip time vary very dynamically , adjust the sending rate equivalent to the amount of tcp throughput may result in a rather fluctuant sending rate . so we present a rate adjustment like tcp congestion control based on aimd , which increases its sending rate by an additive inereease rate
根据mpeg4视频流应用的特点，选择合适的吞吐量模型，进行合理的参数估计，并根据计算出的带宽进行相应的速率调整来实现拥塞控制，我们使用未来rtt的估计值和分组丢失率的估计值作为吞吐量模型的参数，增强了控制的实时性，弱化了业务的振荡性，提高了带宽预测的准确性；在进行速率调整时，不是简单地将发送速率调整到与tcp吞吐量模型一致，而是采用类似tcp的aimd策略来调节发送速率，减小了发送速率的振荡性。
