During June 2025, Michael Froman developed end-to-end round-trip time (RTT) tracking for ICE and STUN within the WebRTC stack in the mozilla/gecko-dev repository. He implemented RTT measurement in nICEr, surfaced RTT metrics in ice_candidate_pair structures, and extended both RTCIceCandidatePairStats and NrIceCandidatePair with fields for totalRTT, currentRTT, and responsesReceived. Using C, C++, and JavaScript, Michael ensured RTT data was exposed through WebIDL interfaces, enabling richer network diagnostics and supporting adaptive connection management. His work addressed Bug 1371391, demonstrating depth in network programming and API design by plumbing RTT metrics across core ICE and WebRTC components.

June 2025 — mozilla/gecko-dev: Delivered end-to-end RTT tracking for ICE/NICE WebRTC. Implemented RTT measurement for STUN, surfaced RTT in ice_candidate_pair, and extended RTCIceCandidatePairStats and NrIceCandidatePair with totalRTT, currentRTT, and responsesReceived. RTT data is exposed end-to-end, enabling richer network diagnostics and supporting adaptive connection management. Changes touched core ICE components (including nICEr) and WebIDL/Smaug interfaces; aligned with Bug 1371391. Series of commits implemented RTT plumbing from STUN to public stats across the ICE stack.
