What I observed

Use HTTP2 to establish and maintain the connection.

Use GPRC to transmit HEADERS and PAYLOAD (using protobuf).

Is it multiplexed

I can see that there is Stream ID on the HTTP2 protocol, so I guess that GPRC uses HTTP2 multiplexing.

Yes, you're right!

I'll add the document to explain how the gRPC server-side and client-side work in the future.

You need to know the gRPC transport layer protocol if you want to get more.

If you are interested in that, I recommend you to know

  • NettyServerTransport.java
  • NettyServerHandler.java
  • Http2HeadersDecoder.java
  • Http2HeadersEncoder.java
  • Http2FrameReader.java
  • Http2FrameWriter.java

These will help you understand better.
