Describing and configuring a computer network is a hard task. Most of the configuration work is performed manually, and furthermore this process depends on vendor specific features of network devices. NetML was born as an effort to tackle this problem.
NetML is an XML based, open source markup language to describe computer networks. The main objectives taken into account in defining it are:
In order to test the generated configurations, the NetML tools also allow to create a script that can be used with the Netkit network emulation toolkit. This eases experimenting with the network before deploying it on real devices.
The approach used within the NetML project is the one typically adopted when dealing with XML based languages. Network descriptions are written according to the NetML grammar (i.e., an XmlSchema instance). XSLT (eXtensible Stylesheet Language Transformations) is then used to generate the configuration files for different types of routers and firewalls.
