%% An example Diameter server that can respond to the base protocol
%% RAR sent by the client example.
%%
%% The simplest example to start a server listening on the loopback
%% address (which will serve the example usage given in client.erl) is
%% like this assuming diameter is already started (eg. diameter:start()):
%%
%% server:start().
%% server:listen(tcp).
%%
%% The first call starts a service, the second adds a transport listening
%% on the default port.
%%
-module(server).
-export([start/1, %% start a service
start/2, %%
listen/2, %% add a listening transport
stop/1]). %% stop a service
%% Convenience functions using the default service name.
-export([start/0,
listen/1,
stop/0]).
-define(DEF_SVC_NAME, ?MODULE).
%% The service configuration. In a server supporting multiple Diameter
%% applications each application may have its own, although they could all
%% be configured with a common callback module.
-define(SERVICE(Name), [{'Origin-Host', atom_to_list(Name) ++ ".example.com"},
{'Origin-Realm', "example.com"},
{'Vendor-Id', 193},

{restrict_connections, false},
{string_decode, false},
{application, [{alias, common},
{dictionary, diameter_gen_base_rfc6733},
