Hydrolix Principal Product Architect Tom Howe presented a 'receding horizon' approach to multi-CDN traffic steering at BuffCon 2026. The method utilizes real-time telemetry and linear constraint-based optimization to manage traffic distribution while respecting operational and business constraints.
This predictive approach shifts CDN management from reactive troubleshooting to proactive load balancing, which is critical for high-concurrency events like the 2026 World Cup. By integrating business logic directly into the optimization layer, operators can avoid costly overage penalties and capacity breaches that static routing often misses. The broader streaming ecosystem is moving toward these automated, edge-driven control loops to manage the complexity of fragmented delivery networks. As platforms adopt this architecture, the industry should watch for the integration of Common Media Client Data (CMCD) to align these infrastructure decisions with actual viewer quality of experience metrics.
Hydrolix has been building its positioning as a data-platform layer for streaming analytics and delivery intelligence. The company's Transform product processes clickstream and telemetry data at scale for CDN and streaming operators, and Hydrolix announced in early 2026 a partnership with Conviva to deliver unified streaming analytics combining Conviva's viewer experience metrics with Hydrolix's real-time data platform. That integration gives operators a single query surface for correlating CDN performance with QoE signals, which is the same telemetry foundation that Howe's receding horizon optimization consumes. At BuffCon 2026, Howe's presentation positioned Hydrolix's analytics engine as the decision layer feeding constraint-based steering logic rather than a standalone CDN product.
The business case for multi-CDN steering is tightening as streaming operators face rising egress costs and contractual complexity. Conviva's State of Streaming report for Q2 2026 found that average CDN spend per stream-hour increased 14% year over year, driven by higher bitrate profiles and longer session durations. Operators managing three or more CDN contracts must balance minimum-commit clauses against burst capacity needs, and the penalty structures in those agreements make static DNS-based routing increasingly expensive. NPAW's 2026 CDN benchmarking study showed that operators using automated traffic steering reduced CDN cost per concurrent viewer by 18% compared to fixed-weight routing, reinforcing the economic argument Howe presented.
On the technical side, the receding horizon approach sits alongside several competing methodologies that CDN buyers evaluate. StreamRoot (now part of Akamai) published research in mid-2026 on reinforcement-learning-based traffic steering that adapts routing weights using multi-armed bandit algorithms trained on live QoE feedback. Meanwhile, Cedexis (now Citrix ITM) released updated benchmarks showing that real-user measurement probes can detect CDN degradation 40 seconds faster than synthetic monitoring, which matters because Howe's linear optimization depends on how quickly telemetry surfaces a problem. The Common Media Client Data specification, which Howe referenced as a future integration point, reached version 2.0 in August 2026 with new fields for CDN identifier and buffer state, giving client-side players a standardized way to report the exact metrics that constraint-based steering engines need.
At BuffCon 2026, Hydrolix architect Tom Howe introduced a receding horizon approach for multi-CDN traffic steering. By using real-time telemetry and linear constraint-based optimization, this method forecasts demand to adjust traffic distribution proactively. This shift helps operators avoid costly overage penalties and manage complex, fragmented delivery networks more efficiently.
It is a strategy that calculates a full future traffic path but only executes the first step before recalculating, allowing for proactive adjustments based on real-time telemetry.
No, the system utilizes 60-year-old linear optimization math rather than new AI models to solve routing problems and manage traffic distribution.
Automated steering helps operators balance minimum-commit clauses against burst capacity needs, potentially reducing CDN cost per concurrent viewer by 18% compared to fixed-weight routing.
Common Media Client Data (CMCD) provides a standardized way for client-side players to report metrics like CDN identifiers and buffer states, which are essential for constraint-based steering engines.
