Intercampus redundancy/redundant router project
The goal of this project is to implement redundant routing in the core UCAR network so that the failure of a single switch does not take the entire campus down. Another benefit of redundant routers is that upgrades are less impacting to the campus. Part of the project includes optimizing spanning tree for fast convergence and protection. This project also involved a UCARnet backbone upgrade to 10 Gbps for improved performance and reliability.
This image shows the UCARnet router
topology with redundancy in place. The UCARnet routing infrastructure
supports the entire network infrastructure across campuses and to the
outside world. This new topology provides increased speed, robustness,
and resiliency to the network
This work directly supports NCAR's strategic goal to "Provide robust, accessible, and innovative information services and tools" and is supported through UCAR Communications Pool indirect funds.
