*Explainer* *No information provided* *Specification* https://datatracker.ietf.org/doc/draft-hancke-tsvwg-snap *Summary* WebRTC Data Channels use the Stream Control Transmission Protocol (SCTP) over a Datagram Transport Layer Security (DTLS) association. The standard SCTP connection establishment requires a handshake that introduces latency. A new Internet draft specifies a method to accelerate the datachannel establishment by embedding the SCTP initialization parameters within the Session Description Protocol (SDP) offer/answer exchange. This reduces the time required to open a data channel by up to two network round-trip times. *Blink component* Blink>WebRTC>DataChannel <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EWebRTC%3EDataChannel%22> *Web Feature ID* webrtc <https://webstatus.dev/features/webrtc> *TAG review* n/a, part of WebRTC covered by IETF drafts *TAG review status* Not applicable *Goals for experimentation* This feature should be gated until the IETF has had a chance to adopt the current draft into a WG and we know whether changes will be required. *Risks* *Interoperability and Compatibility* *No information provided* *Gecko*: No signal *WebKit*: No signal *Web developers*: No signals *Other signals*: *WebView application risks* Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? *No information provided* *Ongoing technical constraints* *No information provided* *Debuggability* *No information provided* *Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?* Yes *Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?* No *Flag name on about://flags* *No information provided* *Finch feature name* WebRtcSctpSnap *Non-finch justification* *No information provided* *Requires code in //chrome?* False *Tracking bug* https://issues.webrtc.org/issues/426480601 *Measurement* The UMA WebRTC.PeerConnection.NegotiatedSctpSnap is measured at connection setup, allowing measurement of the percentage of connections using the feature. *Estimated milestones* Origin trial desktop first 151 Origin trial desktop last 156 *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5137946677215232?gate=5354650258767872 This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
