NDL - Network Description Language - is an ontology for description of (hybrid) networks, aimed at facilitating the inter and intra domain lightpath provisioning. The GLIF collaboration makes use of NDL to describe each individual domain, allowing for example the generation of global GLIF network maps.
This page will provide you with tools to validate an NDL file. We provide here two types of validation:
We can validate that the NDL file you generated is written following the latest NDL schema. You just need to cut and paste it in the space below and you will get back feedback on its validity.
Often NDL files reference information contained in other files managed by others. Such as for example when an interface on a local device connects to an interface to a remote device. The content validator performs a few basic checks to see that the information contained in cross-referencing NDL files is consistent.
