A Lightweight Approach to Network Positioning

Deployment

We have implemented a fully functional Meridian prototype which is currently deployed across approximately 413 Meridian nodes. The framework currently supports finding the closest (lowest latency) node to a given target, the most centrally located node to a given target set, and a node within latency bounds of multiple targets. We have created an online demonstration of these three applications in the following webpages that allows the user to specify arbitary websites as targets, as well as arbitary latency bounds to the targets for the multi-constraint application.

We have also embedded Meridian Query Language interpreters into the deployed Meridian nodes. This allows custom routing queries written in the Meridian Query Language to be submitted to the Meridian nodes.
