Input and output formats for SNDlib

On this page, you find the necessary formats for specifying network planning instances and their solutions.

Each SNDlib instance consists of two input files:

A network file describing the network (nodes, links, demands, and admissible paths), and
a network model file describing the capacity and routing model, whether links are directed or undirected, etc.

Furthermore, there is a solution format for specifying feasible solutions. For all three file types, two possible formats are provided: a native ASCII format and an XML format. You can choose either of them.

Native ASCII:
- Format conventions
- Network model file: format description, example
- Network file: format description, example
- Solution file: format description, example (with detailed cost analysis)
XML:
- HTML documentation
- Network model file: XML schema file, example
- Network file: XML schema file, example
- Solution file: XML schema file, example
