MUX - gRPC+TLS

[hawshemi]

Hello. I the table below:

It is said that Vless+gRPC+TLS (with Nginx) comes with MUX.

1. What is the default number of mux?
2. There is no need to set mux from the client in this config? or do I have to set mux? (like below)

            "mux": {
                "enabled": true,
                "concurrency": 8, 
                "xudpConcurrency": 8, 
                "xudpProxyUDP443": "reject"
            }

I'm also not sure what the default MUX is for gRPC.

            "mux": {
                "enabled": true,
                "concurrency": -1,  
                "xudpConcurrency": 8, 
                "xudpProxyUDP443": "reject"
            }

"concurrency": -1,

The gRPC MUX conflicts with Xray's built-in TCP MUX, which you can turn off like this. But you can use the new UDP MUX feature in XUDP. This new feature is not necessary, you can try it, it is UDP over TCP, it will not conflict with gRPC's MUX.

So when the transport is gRPC, mux is automatically enabled and used by the client and server?

yes This is a fundamental feature of gRPC (HTTP2).
