<p>To implement a new carrier for the Erlang distribution, the main
steps are as follows.</p>
+ <note><p>
+ As of ERTS version 10.0 support for distribution controller
+ processes has been introduced. That is, the traffic over a
+ distribution channel can be managed by a process instead of
+ only by a port. This makes it possible to implement large
+ parts of the logic in Erlang code, and you perhaps do not
+ even need a new driver for the protocol. One example could
+ be Erlang distribution over UDP using <c>gen_udp</c> (your
+ Erlang code will of course have to take care of retranspissions,
+ etc in this example). That is, depending on what you want
+ to do you perhaps do not need to implement a driver at all
+ and can then skip the driver related sections below.
+ The <c>gen_tcp_dist</c> example described in the

+ processes and can be worth having a look at if you want to
+ use distribution controller processes.

+ <title>Distribution Module</title>
+ <p>
+ The distribution module expose an API that <c>net_kernel</c> call
+ in order to manage connections to other nodes. The module name
+ should have the suffix <c>_dist</c>.
+ </p>
+ <p>
+ The module needs to create some kind of listening entity (process
+ or port) and an acceptor process that accepts incoming connections
+ using the listening entity. For each connection, the module at least
+ needs to create one connection supervisor process, which also is
+ responsible for the handshake when setting up the connection, and
+ a distribution controller (process or port) responsible for
+ transport of data over the connection. The distribution controller
+ and the connection supervisor process should be linked together
+ so both of them are cleaned up when the connection is taken down.
+ </p>
+ <p>
+ Note that there need to be exactly one distribution controller
+ per connection. A process or port can only be distribution
+ controller for one connection. The registration as distribution
+ controller cannot be undone. It will stick until the distribution
+ controller terminates. The distribution controller should not
+ ignore exit signals. It is allowed to trap exits, but it should
+ then voluntarily terminate when an exit signal is received.
+ </p>
+ <p>
+ An example implementation of a distribution module can be found
+ in
+ <url href="gen_tcp_dist.erl">$ERL_TOP/lib/kernel/examples/gen_tcp_dist/src/gen_tcp_dist.erl</url>.
+ It implements the distribution over TCP/IP using the <c>gen_tcp</c>
+ API with distribution controllers implemented by processes. This
+ instead of using port distribution controllers as the ordinary TCP/IP
+ distribution uses.

+ <title>Exported Callback Functions</title>
+
+ <p>
+ The following functions are mandatory:
+ </p>
+ <taglist>
+ <tag><marker id="listen"/><c>listen(Name) -></c><br/>&nbsp;&nbsp;<c>{ok, {Listen, Address, Creation}} | {error, Error} </c></tag>
+ <item>
+ <p>
+ <c>listen/1</c> is called once in order to listen for incoming
+ connection requests. The call is made when the distribution is brought
+ up. The argument <c>Name</c> is the part of the node name before
+ the <c>@</c> sign in the full node name. It can be either an atom or a
+ string.
+ </p>
+ <p>
+ The return value consists of a <c>Listen</c> handle (which is
+ later passed to the <seealso marker="#accept"><c>accept/1</c></seealso>
+ callback), <c>Address</c> which is a <c>#net_address{}</c> record
+ with information about the address for the node (the
+ <c>#net_address{}</c> record is defined in
+ <c>kernel/include/net_address.hrl</c>), and <c>Creation</c> which
+ (currently) is an integer <c>1</c>, <c>2</c>, or <c>3</c>.
+ </p>
+ <p>
+ If <seealso marker="erts:epmd"><c>epmd</c></seealso> is to be used
+ for node discovery, you typically want to use the (unfortunately
+ undocumented) <c>erl_epmd</c> module (part of the <c>kernel</c>
+ application) in order to register the listen port with <c>epmd</c>
+ and retrieve <c>Creation</c> to use.

+ When using the default configuration, the data to pass
+ over a connection needs to be delivered as is
+ to the node on the receiving end in the <em>exact same
+ order</em>, with no loss of data what so ever, as sent
+ from the sending node.
+ </p>
+ <p>
+ The data delivery order can be relaxed by disabling
+ features that require strict ordering. This is done by

+ record used when setting up the connection. When relaxed
+ ordering is used, only the order of signals with the same
+ sender/receiver pair has to be preserved.
+ However, note that disabling the features that require
+ strict ordering may have a negative impact on performance,
