Amazon Open-Sources Dynamic Traffic Engine via IAB Tech Lab
IAB Tech Lab will develop Amazon Ads’ Dynamic Traffic Engine (DTE) as an open-source framework to improve clarity in programmatic signaling and reduce wasted bid traffic. DTE lets demand-side platforms publish structured, time-bound traffic preferences so supply-side platforms can poll and act on buyer priorities, filtering irrelevant requests and lowering query volume and infrastructure strain. The approach uses a file-based, machine-readable format (with proposals to support Protocol Buffers) and aims for interoperability with agentic advertising protocols. Development will proceed inside IAB Tech Lab’s Open Source Project with input from working groups including the Programmatic Supply Chain group and the Agentic Taskforce. By standardizing intent communication, the framework intends to improve traffic distribution, campaign performance and inventory monetization while cutting operational waste and environmental impact.
A major platform (Amazon Ads) open-sourcing a programmatic traffic-optimization tool can materially improve DSP/SSP efficiency, reduce wasted bid requests and infrastructure costs, and affects programmatic market operations and sustainability.

Amazon vs. The Trade Desk: Supply Path Debate
The article examines a supply-path debate between Amazon and The Trade Desk over duplicated programmatic bid requests and how to reduce waste. Amazon (represented by Dr. Neil Richter) promotes an open scoring model — Dynamic Traffic Engine (DTE), an open-source SDK on GitHub — that evaluates marginal utility per path and can be deployed by SSPs so math, not relationships, select the best route. The Trade Desk (Mike O'Sullivan) advances verification-first tools — OpenPath and the next-generation Open Ads wrapper — to establish a control signal from publisher primary ad servers and prefer direct, high-trust paths. Forrester’s recent Omnichannel Advertising Platforms Wave named Amazon Ads a Leader and placed Trade Desk outside the top three. The piece frames the tradeoff: Amazon gives away algorithms to drive efficiency; Trade Desk builds controlled integrations to reward trusted supply.
