Network Description Language Update

Explore the advancements in network description languages (NDL) presented by Jeroen van der Ham from the System and Network Engineering Research Group at Universiteit van Amsterdam. This outline covers the current provisioning processes, GLIF and GOLE network descriptions, and provides practical steps for generating, publishing, and validating NDL descriptions. Future research directions include pathfinding in GLIF and multi-layer network descriptions. Comprehensive tools and visualizations are available to enhance understanding and collaboration within network infrastructures.

  21. Six easy steps to NDL GLIF • Generate description of the exchange point • Publish description on a webserver • Send URL of description to Kevin • URL is posted on GLIF Resources site • For each external connection: • Once relevant description is available, update your description to link to theirs • Conctact them to do the same • Periodically, the interactive map will be updated to show results

  22. Future Research • Path finding in GLIF • Network Abstractions • Multi-Layer Network Descriptions • Implementation • DRAGON • Phosphorous • …
