This feature is implemented in the well-known project [byedpi](https://github.com/hufrea/byedpi) and supports almost all parameters (some may not be supported on iOS).
🧩 How to Enable Advanced Fragmentation
You can enable it:
* Globally — for the entire application (i.e., for all configurations);
* Locally — only for a specific server.
There are two ways to enable it:
1. Through the application's user interface.
2. By specifying additional parameters inside the server configuration.
The parameter is called
advancedfragment and can be used with the following types: VLESS, VMess, Trojan.Example:
advancedfragment=LS10bHNyZWMgMCtzbSAtZCAwOjI6MytzbQ==
The value of the parameter is a Base64-encoded string. When decoded, it represents a set of flags, for example:
--tlsrec 0+sm -d 0:2:3+sm
Why is this useful?
The byedpi project is quite complex but extremely powerful. Advanced fragmentation allows for flexible traffic fragmentation control and helps bypass sophisticated DPI (Deep Packet Inspection) systems. It can effectively solve many networking challenges.
