  "message": "dcsctp: Ensure RTO is always greater than RTT\n\nThe retransmission timeout (RTO) value is updated on every measured\nRTT and is a function of the RTT value and its stability. In reality,\nthe RTT is never constant - it fluctuates, which makes the RTO become\nmuch larger than the RTT. But for extremely stable RTTs, which we get\nin simulations, the RTO value can become the same as the RTT, and that\nmakes expiration timers be scheduled to the RTT value, and will race\nwith packets that are expected to stop the expiration timer. And that\nrace should be avoided in simulations.\n\nSo ensuring that the RTO value is always greater, if only be a single\nmillisecond, will work fine in these simulations.\n\nBug: webrtc:12614\nChange-Id: I30cf9c97e50449849ab35de52696c618d8498128\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/219680\nCommit-Queue: Victor Boivie \u003cboivie@webrtc.org\u003e\nReviewed-by: Florent Castelli \u003corphis@webrtc.org\u003e\nCr-Commit-Position: refs/heads/master@{#34084}\n",
