Custom gRPC backend?

[kk1...@nyu.edu]

Hi,

I'm interested in trying out gRPC on the top of KCP protocol https://github.com/skywind3000/kcp/blob/master/README.en.md , can anyone point me out which files I should look for this custom port (C++)?  And I also wonder how doable this is.

Thanks,

Kibeom

You would have to implement your own transport.  I don't think there are any public examples of how to do this today.  Java has some, but I am not sure for C++.

Since kcp implements a byte stream interface (as does tcp), probably you could implement grpc_endpoint for it, and layer chttp2 atop that.

An example of setting the stack up on top of an endpoint is contained in channel_create_posix.c and server_chttp2_posix.c (for client and server respectively).

The idea would be: create a grpc_endpoint that wraps kcp, then wrap it with a transport, then a channel, and then bind it into the stack.
