相关业务过程的建模是仿真建模中的一个挑战，但对于获得许多计算机或通信网络的真实仿真模型是必要的。我们提出了一个新的简单的模块表示为ArrivalProcess被包括在OMNeT++仿真模型的流量源。新的流量源支持使用XML格式定义的不同随机过程模型。过程描述可以使用软件工具ProFiDo从跟踪数据自动生成，也简要介绍。通过实例表明，对于具有相关到达流的系统，使用随机过程而不是简单分布会产生更准确的结果。
Modeling of correlated traffic processes is a challenge in simulation modeling but is necessary to obtain realistic simulation models of many computer or communication networks. We present a new simple module denoted as ArrivalProcess to be included as a traffic source in OMNeT++ simulation models. The new traffic source supports different stochastic process models which are defined using a XML format. The process descriptions can be automatically generated from trace data using the software tool ProFiDo which is also briefly presented. By means of examples it is shown that the use of stochastic processes rather than simple distributions results in much more accurate results for systems with correlated arrival streams.
