+
+Fragment TLS handshakes to bypass firewalls.
+
+This feature is intended to circumvent simple firewalls based on **plaintext packet matching**, and should not be used to circumvent real censorship.
+
+Since it is not designed for performance, it should not be applied to all connections, but only to server names that are known to be blocked.
+
+On Linux, Apple platforms, (administrator privileges required) Windows, the wait time can be automatically detected, otherwise it will fall back to waiting for a fixed time specified by `tls_fragment_fallback_delay`.
+
+In addition, if the actual wait time is less than 20ms, it will also fall back to waiting for a fixed time, because the target is considered to be local or behind a transparent proxy.
+
+#### tls_fragment_fallback_delay
+
+!!! question "Since sing-box 1.12.0"
+
+The fallback value used when TLS segmentation cannot automatically determine the wait time.
+
+`500ms` is used by default.

+通过分段 TLS 握手数据包来绕过防火墙检测。
+
+此功能旨在规避基于**明文数据包匹配**的简单防火墙，不应该用于规避真的审查。
+
+由于它不是为性能设计的，不应被应用于所有连接，而仅应用于已知被阻止的服务器名称。

+在 Linux、Apple 平台和需要管理员权限的 Windows 系统上，可自动检测等待时间。若无法自动检测，将回退使用 `tls_fragment_fallback_delay` 指定的固定等待时间。
+
+此外，若实际等待时间小于 20 毫秒，同样会回退至固定等待时间模式，因为此时判定目标处于本地或透明代理之后。
