optrix

• A dataset of publicly available core network topologies
• An analysis-ready dataset of publicly available core optical fibre networks (BT, Internet Topology Zoo, SNDlib, Conus)

Requirements

• NetworkX: A Python library for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.
• NumPy: A fundamental package for scientific computing with Python.
• Matplotlib: A plotting library for creating static, animated, and interactive visualizations in Python.
• Pickle: A module for serializing and deserializing Python objects.

Types of Networks

The code provides a collection of networks from different datasets. Currently, it includes the following datasets:

• SNDLib: A collection of network topologies used for network optimization problems.
• ITZ: A collection of network topologies from the Internet Topology Zoo Dataset.
• BT: British Telecommunication's Core Network BT-22 Published Online
