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.
"RLM gave us an objective view of our network options that no single vendor could. We replaced aging MPLS across 40 locations and came in 28% under our original budget."
The benchmark comes first. Without a baseline, “savings” is just a number a vendor gave you.
Where This Matters Most
Sector-specific considerations we see repeatedly in advanced networking engagements.
