业务拥塞 meaning in Chinese
traffic congestion
Examples
- The main drawback of classic congestion control algorithms for abr service is that they are based on heuristics that do not have a formal theory to back them and / or depend on a number of measurements that are either difficult to perform , or have a significant amount of noise in their estimates
传统的abr业务拥塞控制方案基于启发式法则而没有正式的理论支持，并且依靠一系列的测量值，这些测量值要不是很难测量就是在估计时参生显著的噪声。 - In the second part of this paper , it makes a detailed analysis among fluid - model - based , smith - principle - based and two - pd - controllers - based by comparing to the method and application of control theory . then it gets the laws to keep the control loop stable . in order to analyze the dynamic and transient characters , three congestion control algorithms mentioned above have been carried out in the nist atm network simulator and the successful outcomes are brought out
本论文对atm网络abr业务拥塞控制的控制理论算法进行了总结，简要分析了其优点和缺点；运用控制理论的分析方法和观点对基于流体控制模型、史密斯预估控制模型和双重比例微分控制模型三种拥塞控制算法加以具体的分析，从而分析了怎样确保控制环的稳定性；在nistatm网络仿真软件中嵌入以上三种拥塞控制算法，从而对算法的动态和瞬态特性进行仿真分析，以此证明控制算法的有效性；最后提出了今后atm网络abr业务拥塞控制算法的发展趋势。 - The classical congestion control algorithms for binary abr service mainly based on heuristics and do not have a formal theory to support them , thus they have two drawbacks . one is that the queue length and allowed cell rate ( acr ) oscillate with great amplitude , the other is that the control performance is not as good as we had expected in networks with a long bandwidth delay
但是，传统的二进制abr业务拥塞控制机制大多基于启发式法则而没有正式的理论支持，所以这些方法存在两个不足，一是队列长度和源端允许信元速率呈现振荡性；二是在具有大的带宽时延乘积的网络中，控制效果不佳。
