[asio-users] How to implement my own TCP?

[Chengu Wang]

Hi all,

I'd like to implement the TCP over UDP, because I want to change TCP a
little. The implementation includes the three-way handshake,
retransmission, etc.

My TCP must have the basic interfaces as the original TCP does, i.e. a
my_tcp::acceptor class supporting bind, listen, accept, async_accept and
close, and a my_tcp::socket supporting bind, connect, async_connect, send,
async_send, receive, async_receive and close.

Of course I can write these two classes from scratch, but can I do it in
the framework of asio and reuse some codes of asio? What classes should I
implement and what do the inherit from?

Any help would be appreciated.

TCP is not implemented in ASIO and thus you cant really use the code
to extend it. If you really want to reimplement TCP you might want to
take a look at some of the embedded tcp stacks that exists.

A better approach is probably to understand that you are implementing
your own "safe UDP" protocol and start on that using ASIO UDP. But
then again, ask yourself, why?

Hi Svante,

Thanks for you suggestions.

I don't want to reuse the codes in OS implementing TCP, but I hope to use
some codes in Asio, e.g. basic_stream_socket, reactive_socket_service_base,
buffer_sequence_adapter, reactor_op, task_io_service_operation etc.

I implemented TCP again because I want to change the retransmission
mechanism to make TCP faster.

Hi,

Why not use UDT project?:
http://udt.sourceforge.net/

[Chengu Wang]

Hi niXman,

I know this project. Thanks. UDT is a good choice as well. I will choose
UDT if the async functions are difficult to implement in Asio framework.
The TCP protocol itself is not a problem.
