WAN optimization improves application performance over expensive or constrained WAN links through traffic deduplication, protocol acceleration, compression, and caching — reducing effective bandwidth consumption and improving application response times for users at remote locations.
WAN optimization has evolved significantly in the SD-WAN era — traditional appliance-based WAN optimization has been largely replaced by software-defined approaches, but the underlying techniques remain valuable for bandwidth-constrained or high-latency environments.
A structured advisory process — from discovery and market evaluation to vendor selection and post-deployment optimization — tailored to your specific environment and objectives.
We establish the current WAN performance baseline — application response times, bandwidth utilization, protocol overhead, and the specific performance complaints that motivate the optimization initiative.
We evaluate WAN optimization approaches — SD-WAN-integrated optimization (Riverbed, Silver Peak, Cisco), protocol acceleration, and content caching — against your specific traffic mix and the bandwidth/latency characteristics of your WAN links.
We design the WAN optimization deployment — physical vs. virtual appliances, deployment location (hub-side only vs. branch-to-branch), and integration with existing SD-WAN infrastructure.
WAN optimization ROI must be measured, not assumed. We design the monitoring approach that quantifies bandwidth savings and application performance improvement against the cost of the optimization solution.
These are the dimensions that consistently separate successful network deployments from costly ones — and the questions RLM will help you answer before any commitment.
Traditional WAN optimization is less impactful when most traffic is already cloud-hosted or encrypted end-to-end. Evaluate which applications and traffic types in your environment will genuinely benefit before investing in optimization infrastructure.
Some SD-WAN platforms include built-in WAN optimization capabilities. Evaluate whether integrated optimization meets your requirements before deploying separate WAN optimization appliances.
WAN optimization deduplication and protocol acceleration require visibility into traffic content — challenging with TLS/SSL encrypted traffic. Evaluate the impact of pervasive encryption on optimization effectiveness.
WAN optimization delivers the most value for chatty protocols (SMB, CIFS, database) over high-latency links. Evaluate your specific protocol mix and link characteristics against the optimization gains available.
Cloud SaaS applications are already optimized by their providers. WAN optimization adds little value for Microsoft 365 or Salesforce traffic — evaluate whether your bandwidth-intensive applications are actually optimization candidates.
In some cases, the cost of WAN optimization infrastructure is better invested in migrating applications to cloud with direct internet access. Evaluate optimization ROI against the application migration alternative.
"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 RLM team understood our network complexity from day one. Their vendor-neutral approach helped us find the right solution — not just the one with the biggest marketing budget."
