  "textContent": "The \"More Accurate Explicit Congestion Notification\" (AccECN) mechanism is defined by this RFC draft. The Linux kernel has been gaining support for AccECN with TCP over the last few releases; the 7.0 release will enable it by default for general use. AccECN is a subtle change to how TCP works, but it has the potential to improve how traffic flows over both public and private networks.",
