  1. GlobalRoutesm Service Overview For NANOG 25 June 11th, 2002

  2. Benefits of ‘Service’ • Minimized Risk • Protection against technological obsolescence • Minimize upfront capital expenditures • Scalable • Speed and ease of deployment • Ease of upgrades • Ongoing relationship • 7x24x365 Support • Continuous analysis by BGP/IP networking experts • Alerts

  3. Global Measurements • Exclusive license to platform from Akamai • Discovery of Internet Topology • Active Probing - Proactive detection

  4. Customer-Specific Measurements • Measurements are from Customer POV • Topology Mapping Data combined with local NetFlow data • Static VIPs may be added by the customer

  5. Internet and VPN Optimization GRA ‘whispers’ routes to router via iBGP Customer control of performance and cost parameters, allows flexibility

  6. GlobalRoute Management Console • Starting point for managing GlobalRoute reports and configuration

  7. GlobalRoute Benefits • Improved route selection – We find BGP path selection goes from 30% to 90%+ with GlobalRoute • Enables network engineers to take control of 95% burstable billing – flattens out peaks, resulting in lower transit bills • Cut troubleshooting time

  8. Activity Console

  9. Shortfall • GlobalRoute combines probe results into a composite figure called “shortfall” • Shortfall incorporates both latency and loss • Computation • 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

  10. Flow Data Display • Top customer routables based on flow data • Top prefixes and top AS’es • Indicates static, dynamic, and uncontrolled routables

  11. Latency/Loss/Shortfall • Per-routable latency, loss, and shortfall

  12. Link Comparison • View the difference between any two transit links • See the effects of routing decisions • View data in shortfall, latency, and loss

  13. Route Change History • 30-day history of route changes • Route change details • Link to relevant traceroutes
