Route Every Application Over the Best Available Path
Application-aware routing uses deep packet inspection and application signatures to classify traffic and dynamically route each application over the WAN path that best meets its performance requirements — sending video conferencing over low-latency paths, bulk backup over cost-optimized paths, and sensitive business traffic over private circuits.
What RLM Delivers on Application-Aware Routing
Application-aware routing is what makes SD-WAN genuinely different from policy-based routing on traditional WAN equipment — but the quality of application classification, the granularity of routing policy, and the integration with cloud application on-ramps determines how much of the promised performance improvement you actually realize.
How We Approach Application-Aware Routing
A structured path through the Application-Aware Routing decision — current-state discovery, shortlist and benchmark, commercial negotiation, then support until it is actually working.
Application Traffic Profiling
We analyze your WAN traffic — application mix, bandwidth consumption by application, latency sensitivity, and packet loss tolerance — creating the application profile that drives routing policy design.
Routing Policy Architecture
We design the application routing policies — QoS classes, path preference rules, failover thresholds, and application-specific SLA parameters — that translate application requirements into SD-WAN configuration.
Platform Application Library Evaluation
SD-WAN platforms vary significantly in the breadth and accuracy of their application signature libraries. We evaluate the application recognition coverage for your specific application portfolio — particularly custom or less-common applications.
Performance Validation & Tuning
Application-aware routing must be validated in production — the theoretical routing policy and the real-world behavior under actual traffic loads can differ. We design the validation approach and performance metrics that confirm routing effectiveness.
Application-Aware Routing Evaluation Criteria
Before committing to any Application-Aware Routing platform, these are the points worth forcing a straight answer on.
Application Classification Accuracy
Application-aware routing is only as good as the application classification. Evaluate recognition accuracy for your specific applications — encrypted traffic, custom applications, and cloud SaaS must all be correctly identified.
Real-Time Path Quality Measurement
Routing decisions require real-time path quality data — latency, jitter, and packet loss measured continuously. Evaluate the measurement frequency and accuracy of path quality monitoring for each underlay transport.
Policy Granularity
Some SD-WAN platforms provide per-application routing policies; others work at a QoS class level. Evaluate the policy granularity available against your application requirements — particularly for latency-sensitive communications applications.
Failover Speed
When an application's preferred path degrades, routing must fail over quickly enough to prevent user-perceptible disruption. Evaluate failover detection time and switchover speed for your latency-sensitive applications.
Cloud SaaS Traffic Handling
Cloud SaaS applications like Salesforce, Microsoft 365, and Zoom benefit from direct internet breakout with intelligent path selection. Evaluate cloud on-ramp integration and the SaaS application steering capability.
Reporting & Visibility
Application performance visibility over time is essential for optimization. Evaluate reporting capabilities — application-level performance trends, policy effectiveness metrics, and capacity planning data.
The benchmark comes first. Without a baseline, “savings” is just a number a vendor gave you.
