GlobalRoute Benefits

Improved route selection – We find BGP path selection goes from 30% to 90%+ with GlobalRouteEnables network engineers to take control of 95% burstable billing – flattens out peaks, resulting in lower transit billsCut troubleshooting time

Shortfall

GlobalRoute combines probe results into a composite figure called “shortfall”

• Shortfall incorporates both latency and lossComputation

• Shortfall is scaled between 0 and 100• Latency greater than 1500ms (configurable) is considered loss• For each routable, each set of scanpoint probes is scored using

their weights to determine an average• Latency is treated linearly, and then loss is incorporated

• For each instance of packet loss there is an additional penalty in the shortfall computation

• Data is smoothed to minimize the impact of spikes and transient noise

There is an effort to model shortfall to actual performance
