%% An example Diameter relay agent.
%%
%% Usage to connect to a server listening on the default port over TCP
%% and to listen on the default port over SCTP is as follows, assuming
%% diameter is already started (eg. diameter:start()).
%%
%% Eg. relay:start().
%% relay:connect(tcp).
%% relay:listen(sctp).
%%
-module(relay).
-export([start/1,
start/2,
listen/2,
connect/2,
stop/1]).
-export([start/0,
listen/1,
connect/1,
stop/0]).
-define(DEF_SVC_NAME, ?MODULE).
%% The service configuration.
