NS-2 快速tools之nsBench 介绍： nsBench makes NS-2 simulation development and analysis faster and easier for students and researchers without losing the flexibility or expressiveness gained by writing a script. The goal of nsBench project is to develop supporting tools that enable creating, analyzing and visualizing NS-2 simulation scripts and traces automatically. GUI 安装 安装jvm 运行 $java? -jar? nsBench-1.0b3.jar 官方tutorial Installing NSBench Download and store NS in C:\NSW. Download NSBench and store in C:\NSW. Download and install Java 1.4 or later. Download and install the ConTEXT editor. ConTEXT is not necessary for the operation of NSBench, however it provides a convenient text editor for TCL scripts. Using NSBench Start nsBench by double clicking the nsBench.jar icon in windows Explorer. In unix and linux, open x terminal, then type “java -jar nsBench103b.jar” to start nsBench. Use the top menus to save files, set NS global configuration and generate the TCL script. Use bottom menus to create NS objects. Choose your file names for the simulation project. Open Configuration menu and choose Trace. Create network nodes. Click the circle icon, or select the insert menu and select Node. Create a network links. Click and drag the mouse from the point on the center of one node (cursor changes to hand) to the center point of the other node. To configure the created link, double click the mouse on any point on the link. 7. Attach transport agents to nodes. To attach an TCP agent to a node first select the node. Then, open the insert menu and select TCP, or click on the square icon and select the agent. 8. You can now create a sink agent and connect it to the other node. To do that follow the same steps as in step 7, but select n1 prior to starting. 9. To configure the TCP agent, double click on the TCP object. 10. Create a transport connection between the two TCP agents by connecting the center points of both TCP objects. 11. Create application or traffic genera
