I have two Java netty servers that need to pass lots of messages between themselves fairly frequently and I want it to happen fairly promptly.

I need a TCP socket between the two servers that I can send these messages over.

These messages are already-packed byte[] arrays and are self-contained.

The servers are currently both running HTTP interfaces.

What is the best way to do this?

For example, websockets might be a good fit yet I am unable to find any websocket client examples in netty..

I’m a netty newbie so would need some strong simple examples. It surely can’t be so hard?!

    Since you mentioned HTTP, you could look at the HttpStaticFileServer in the examples.

    When established, a TCP connection is a Channel. To send your messages, you need to write them to a ChannelBuffer and call channel.write.

    Of course, this does not cover message borders. The Telnet example shows a case, where the messages are delimited by the newline character.
