Diagnosing Internet routing issues is challenging due to data volume. Link-Rank visualizes global routing changes, helping network operators identify problems and understand network events.
Area of Science:
- Computer Science
- Network Engineering
Background:
- Internet routing protocols are crucial for global data delivery.
- Diagnosing routing problems is difficult due to the Internet's scale and data volume.
Purpose of the Study:
- To develop a tool for visualizing global Internet routing changes.
- To assist network operators in identifying and diagnosing routing issues.
Main Methods:
- Developed Link-Rank, a tool that visualizes Internet routing changes.
- Link-Rank weighs links in a topological graph by the number of routes carried.
- The tool visually captures changes in link weights in an adjustable-size topological graph.
Main Results:
- Link-Rank enables observation of important routing changes from massive data.
- Facilitates discovery of unnoticed routing problems.
- Aids in understanding the impact of topological events and inferring root causes.
Conclusions:
- Link-Rank provides a scalable solution for visualizing global routing dynamics.
- Network operators can effectively manage and troubleshoot Internet routing using Link-Rank.
