A new quality‑of‑service mechanism called the Verifiable Agentic Traffic Class (VATC) lets routers confirm that packets come from a large‑language‑model agent and serve those packets first, but only up to a fixed rate. VATC reserves a specific Differentiated Services Code Point (DSCP) number, uses a router‑side engine that compares the claimed DSCP with the actual flow, and places verified traffic in a policed priority queue.

In tests that matched real‑world Linux kernel behavior, VATC matched the performance of a static DiffServ class when traffic was steady. During a constructed burst, VATC cut the average queuing delay for agent traffic by 98 % compared with DiffServ while only raising human traffic delay by 12 %. Under a spoofed flood, the rate limit kept human delay 11 times lower than with DiffServ.

The work relied on a traffic generator built from publicly released statistics, so the results show VATC’s behavior for traffic that follows those signatures. They do not prove that real agent traffic will match those patterns or that all spoofers can be detected.

VATC therefore offers a safe way to give newly‑created agent traffic priority without risking a denial‑of‑service for normal traffic, as long as the traffic matches known agent signatures.
