ROA Performance Explorer

Blue Planet Route Optimization and Assurance product’s Performance Explorer application collects and reports SNMP-based performance data (e.g. availability, CPU, memory, latency, packet loss, jitter, etc.) from all network devices under management. Working in combination with ROA Route Explorer and ROA Traffic ExplorerPerformance Explorer completes the industry’s first unified, path-aware network service assurance solution, and complements existing SNMP tools.

ROA Performance Explorer correlates routing events with latency and performance metrics to help network professionals understand how service delivery is affected by network routing behavior. With real-time and historical visibility into service paths and device performance network-wide, engineers can now optimize their networks with unprecedented accuracy and speed.

Key Benefits

  • Reduce SLA breaches with proactive monitoring of infrastructure performance and real-time alerts for early threat detection
  • Enable fast incident triage with performance alerts, operations dashboards, and intuitive workflows for problem isolation and diagnosis
  • Improve MTTR and customer satisfaction by detecting network hotspots that traditional tools miss
  • Make more informed engineering decisions by knowing how routing path changes will impact latency and other performance metrics
  • Replay the network’s behavior to quickly identify the cause of transient, performance-impacting issues
  • Provide customers with detailed hop-by-hop performance metrics of overlay services, like Layer 2 and Layer 3 VPNs, when required

Product Capabilities

Troubleshooting & Remediation
ROA Performance Explorer application provides historical performance metrics in context with routing events and traffic flows from other ROA applications. This unique correlation helps network professionals troubleshoot the hard-to-find, intermittent service delivery problems that traditional network monitoring tools miss because they cannot see dynamic routing events and their impact on traffic flows across the network.

Network operations staff are alerted to potential service-impacting performance issues based on deviations from adaptive baselines. They can use the product’s built-in, intuitive dashboards to drill down into the specific links or devices in question to see both the routing events and performance metrics in context. And the incorporated guided workflows enable staff to troubleshoot and perform triage more efficiently, resulting in lower Mean Time To Resolve (MTTR) and overall improved service delivery.

Risk Mitigation
The majority of network disruptions and outages are due to misconfigurations. ROA Performance Explorer, when used in conjunction with ROA Route Explorer, enables network engineers to more confidently and accurately model network changes before they are implemented.
Modeling changes using the real-time performance monitoring data on the live network instead of imported models that may be out of date, increases modeling accuracy. Modeling interactively instead of using offline processes also speeds up the change management process.

Being able to see the impact of planned changes before they are made helps to avoid disruptions and outages from misconfigurations during maintenance windows. This results in improved service availability and reliability, and happier customers.

Network Resiliency Engineering
Performance Explorer helps optimize network resiliency and overall service delivery by identifying and isolating service-impacting performance hot spots. Performance issues on specific paths or links, such as excessive latency, jitter or packet loss, are identified immediately.

Engineers can ensure there is adequate fail-over capacity for key services by modeling failure scenarios to see the impact on latency and other performance metrics.

Proactive SLA Management
ROA Performance Explorer helps network operators be more proactive in managing the performance of critical services and more effective in triaging issues when they arise. Alerts to deviations from network performance baselines help staff identify issues before they escalate and intuitive drill-in workflows with contextual analytics guide them to the source.

Performance Explorer's summary dashboard highlights performance deviations and errors, and provides an at-a-glance view of the network with key infrastructure and service delivery metrics. Baselines are established by hour of day and day of week for performance metrics, such as CPU and memory utilization, errors, jitter, and latency, using geometric averaging to weight more recent data. Deviations of more than 25% are flagged on the dashboard, helping network staff to identify potential network issues, analyze them, and often resolve them before clients or end-users even notice.

Performance dashboards can also be used by engineers to understand trends, plan for network changes and growth, and verify changes made during scheduled maintenance. By clicking on dashboard elements, operations and engineering staff can drill-in on emerging network hotspots for device and link-level analysis to help them determine the best course of remedial action.

Having accurate routing, traffic and performance analytics not only helps to improve network resiliency and overall service delivery levels, but also helps staff defend the network from being unfairly blamed when problems arise.
