Troubleshooting and Diagnostics
Route Explorer’s real-time monitoring and analysis of your network’s routing topology provides the following unique benefits in network diagnosis and troubleshooting:- Rapid isolation of the problem area helps bring the appropriate resources to bear on the problem. Is it a routing problem or is it in the server?
- Always up-to-date network documentation allows instant assessment of the extent of the outage and collateral damage.
- Faster isolation of the problem reduces the total time of outage, saves money.
- Detailed history-based post-mortem analysis enables improved network design and process to avoid future outages.
