Abstract

We identify three goals for the graphical user interface (GUI) of a network simulation environment: user friendliness, model re-usability, and application extensibility. We address the user friendliness issue by proposing a simple yet efficient approach to setup parameters for the simulation models. We address the application extensibility issue by a two-layer GUI architecture. The two layers are loosely-coupled, and the first layer can be easily replaced (without affecting the other components of the simulation environment). We address the model re-usability issue by subnetworks. Unlike most existing simulation packages where subnetwork is simply a method to group the nodes, the subnetwork construct in our approach is an integral part of the simulation environment (i.e., all operations for a basic node also apply to a subnetwork). The port concept is used to explicitly define the I/O relationship between a subnetwork and the outside world. Parameter dialog boxes are used to set up the parameters for a subnetwork conveniently. Finally, a simple stack mechanism is proposed to measure subnetwork-wide output statistics.<>

用于性能建模的灵活图形用户界面

我们确定了网络仿真环境的图形用户界面(GUI)的三个目标:用户友好性、模型可重用性和应用程序可扩展性。我们通过提出一种简单而有效的方法来设置仿真模型的参数来解决用户友好性问题。我们通过两层GUI架构来解决应用程序的可扩展性问题。这两层是松耦合的，第一层可以很容易地替换(而不会影响模拟环境的其他组件)。我们通过子网解决了模型的重用性问题。与大多数现有的仿真软件包不同，其中子网只是对节点进行分组的一种方法，我们方法中的子网构造是仿真环境的一个组成部分(即，对基本节点的所有操作也适用于子网)。端口概念用于显式定义子网与外部世界之间的I/O关系。通过参数对话框，可以方便地设置子网的相关参数。最后，提出了一种简单的堆栈机制来测量子网范围内的输出统计
