New Framework Aligns with Agentic Real-Time Framework to Enable Smarter Demand Signaling and Reduce QPS Waste Across the Supply Chain – In a move that could reshape programmatic advertising, IAB Tech Lab announced today the open‑source donation of Amazon Ads’ Dynamic Traffic Engine (DTE). The new framework lets demand‑side platforms (DSPs) broadcast granular bidding priorities to supply‑side platforms (SSPs) in real time, promising to slash query‑per‑second (QPS) overload and improve revenue yields for both buyers and sellers.
What the Dynamic Traffic Engine Does
The Dynamic Traffic Engine introduces a file‑based signaling protocol that DSPs can update with the types of bid requests they wish to receive—ranging from broad inventory categories to hyper‑specific audience segments. SSPs poll these files and filter incoming ad calls accordingly, eliminating unnecessary impressions before they hit the exchange. By reducing the volume of low‑value requests, the DTE directly lowers the QPS load that has become a bottleneck for ad tech infrastructure.
Why the Announcement Matters
Programmatic ecosystems have long grappled with “QPS waste,” a phenomenon where billions of bid requests are generated but only a fraction translate into meaningful transactions. A 2023 Forrester study estimated that up to 35 % of programmatic traffic is discarded due to mismatched inventory, costing the industry roughly $4 billion annually in wasted compute and bandwidth. The DTE’s proactive signaling tackles this inefficiency at the source, offering a scalable path to lower operating costs and improve latency—a critical factor for real‑time bidding (RTB) on Connected TV (CTV) and Over‑the‑Top (OTT) platforms.
Industry Impact and Competitive Context
While Google’s OpenRTB extensions and the Trade Desk’s “Unified ID 2.0” focus on identity and measurement, the DTE is the first open‑source effort that standardizes demand‑side intent signaling. Competing solutions, such as Amazon’s proprietary “Ad Quality Signals” and Microsoft’s “Advertising Insights API,” remain closed ecosystems. By contrast, the DTE’s open‑source nature invites broader adoption and community‑driven enhancements, potentially setting a new baseline for industry interoperability.
Implications for Enterprise Marketing Teams
For marketers, the DTE could translate into more predictable inventory quality and lower CPMs. By ensuring that each bid request aligns with a DSP’s declared priorities, campaigns are less likely to waste budget on irrelevant impressions. Early adopters may also benefit from richer performance analytics, as the reduced noise in the bid stream simplifies attribution modeling. In practice, a retail media network could configure its DSP to prioritize premium, brand‑safe inventory during high‑traffic shopping events, while an enterprise using a Customer Data Platform (CDP) could surface first‑party audience segments directly to SSPs without additional data onboarding steps.
Technical Outlook
Implementation will be managed through IAB Tech Lab’s Open Source Initiative, with the first reference implementation slated for integration into the Agentic Advertising Management Protocols (AAMP). The framework’s reliance on simple file polling makes it compatible with existing ad servers and cloud‑native architectures, reducing the barrier to entry for mid‑size SSPs that lack the resources to build custom signaling layers.
Future Directions
The DTE’s open architecture opens the door for machine learning‑driven demand signaling. As models refine audience predictions, DSPs could automatically adjust their priority files in near‑real time, creating a feedback loop that continuously optimizes inventory allocation. Such a capability would dovetail with emerging privacy‑first initiatives, allowing firms to leverage first‑party data while respecting regulatory constraints.

Market Landscape
Programmatic ad spend is projected by Gartner to exceed $150 billion in 2025, with CTV and OTT accounting for a growing share of that total. Yet, the same reports flag rising infrastructure costs as a limiting factor for continued growth. IDC predicts that by 2027, the average QPS per SSP will double, pressuring operators to adopt efficiency‑driven technologies. In this context, the Dynamic Traffic Engine arrives as a timely solution that addresses both cost and performance challenges.
Top Insights
- Proactive demand signaling: DTE lets DSPs broadcast exact inventory preferences, cutting unnecessary bid requests at the source.
- Open‑source advantage: Unlike proprietary alternatives, the framework invites cross‑industry collaboration and faster standardization.
- Cost impact: Reducing QPS waste could save the industry up to $4 billion annually, according to Forrester.
- Enterprise benefits: Marketers gain tighter budget control and clearer attribution by filtering out low‑value impressions.
- AI‑ready foundation: The file‑based model can evolve into real‑time, machine‑learning‑driven priority updates.
