Thank you very much for your reply.

I did what you said, but the behavior is very confusing.

I create two channels in lua script, and correspond each channel to a pair of client and server threads.

In the server side, each thread registers its own server obj to its own Registry_server, and of course they have different dispatch functions.

Now the result is only one server thread receive all requests from client, and it selects different dispatch function to run based on the request.

But I want different threads to run different dispatch function, not only one server thread process all requests using different dispatch functions.

Do you have any ideas about this?

Thank you.

The simple client/server example
(http://wiki.tudos.org/L4Re_simple_client_server_example) shows how to
connect a single thread in each process (or task in L4 speak). You
could extend this example to create two channels in the Lua setup
file, pass both channels to the tasks during startup and then let each
thread use one of them for communication with its counterpart.

Note that does not completely enforce your requirement that each
thread can only talk to exactly one other. Capabilities (e.g., for the
communication channels) are shared per task and technically each
thread could therefore send messages on each channel. If you want
strict isolation, you have to separate the threads into separate tasks.
