Extended Network Simulator NS-2 Nam Editor
The Extended Nam Editor is an editor that allows the graphical creation of ns2 scripts. It extends the basic Nam Editor with the following features:
- Integration with existing topology generators
- Localization and visualization of set of nodes on large network topologies according to different selection criteria;
- Instantiation of agents of any types on all the nodes of a given node set;
- Definition of new node types;
- Support for simulations of web cache systems.
Topology Generator Interface
The manual generation of complex Network Topology is a tedious and error prone activity.
In order to simulate networks with realistic topologies, it is a common practice to use ad-hoc topology generators, whose output is usually not compatible with the ns2 syntax. Hence, several tools have been developed to translate topology descriptions generated by topology generators in ns-scripts that can be used in the definition of a simulation scenario.
Unfortunately, scripts produced in this way are not compatible with the Nam Editor, hence networks created by common topology generators cannot be modified interactively. Such a limitation is sometimes annoying, in particular when the automatically generated topology needs to be further adapted, e.g. by instantiating agents on particular network nodes.
Nam-Editor provides a graphical interface to:
- GT-ITM topology generator;
- INET topology generator;
It is now possible to create, visualize and modify topologies created according to the following topology models:
- flat-itm;
- hierarchical-itm;
- transit-stub-itm;
- INET;
