Vodafone has selected CUJO AI to deploy its IETF-standardized Quality of Outcome (QoO) technology across its European broadband networks. The platform shifts network assessment from raw speed metrics to application-specific performance scores to better optimize for latency-sensitive services like video conferencing and gaming.
This deployment signals a shift in how internet service providers justify value beyond the 'speed tier' marketing that has dominated the industry for a decade. By adopting the IETF-standardized QoO metric, Vodafone can identify specific network bottlenecks affecting high-bandwidth, low-latency streaming and cloud services that raw throughput figures often mask. For the broader streaming ecosystem, this provides a more granular feedback loop between the network layer and application performance, potentially reducing churn caused by intermittent buffering or lag. Watch for whether other major European telcos adopt similar IETF standards to compete on service reliability rather than just gigabit headlines.
Vodafone's deployment marks the first large-scale European rollout of CUJO AI's Quality of Outcome framework, which the company has been developing in collaboration with the IETF's IP Performance Measurement Working Group. ISPreview reported that Vodafone will deploy the AI-based measurement tool across millions of Wi-Fi 7 capable broadband home hubs in Europe, including the UK, converting latency, packet loss, and throughput into per-application scores that help the operator pinpoint where specific services like video calls or gaming degrade.
The IETF standardization process for Quality of Outcome is nearing completion. The IETF draft, designated draft-ietf-ippm-qoo-11, was submitted to the IESG for publication and sits in the RFC Editor queue as of August 2026, authored by CUJO AI's Bjørn Ivar Teigen Monclair and Magnus Olden with Ike Kunze as editor. The draft specifies that QoO scores express network conditions as a percentage on a linear scale bounded by two application-specific thresholds: 0% at the Conditions at the Point of Unacceptable Performance and 100% at the Requirements for Optimal Performance. The overall score is the minimum of latency, packet-loss, and throughput component scores, reflecting the principle that the most degraded dimension determines perceived application quality.
CUJO AI has also released qoo-c, an MIT-licensed open-source C library that implements the full QoO specification, alongside partial support in goresponsiveness, an open-source network quality test written in Go. Telecompaper confirmed that the CUJO AI technology is already live on one Vodafone broadband network, with further rollout underway across additional European markets. Vodafone has tested QoO alongside its Low Latency DOCSIS initiative to assess how network improvements translate into better performance for latency-sensitive applications, positioning the deployment as a complement to its ongoing speed upgrades rather than a replacement.
Vodafone is deploying CUJO AI’s Quality of Outcome (QoO) standard across its European broadband networks. By replacing traditional speed metrics with application-specific performance scores, the operator can better identify network bottlenecks. This shift allows Vodafone to optimize for latency-sensitive services like gaming and video conferencing, moving beyond simple speed-tier marketing.
The QoO standard is an IETF-standardized metric that converts network conditions like latency, packet loss, and throughput into specific performance scores for different applications, rather than relying on raw speed.
Vodafone is adopting QoO to better identify network bottlenecks that affect high-bandwidth, low-latency services, allowing them to improve reliability and reduce churn caused by buffering or lag.
The score is expressed as a percentage on a linear scale, where 0% represents unacceptable performance and 100% represents optimal performance, based on the most degraded dimension of latency, packet loss, or throughput.
Yes, Telecompaper confirmed that the CUJO AI technology is already live on one Vodafone broadband network, with a wider rollout currently underway across additional European markets.
