小结：

server:

   ACE_INET_Addr:提供一个port来初始化一个服务器端saddr_in结构全为零，同时调整字节序。

   ACE_SOCK_Acceptor:提供了两个方法.

       open()--以正确的顺序调用socket, bind, listen.

       accept()-- 接受来自客户端的连接请求并初始化ace_sock_stream.

   ACE_SOCK_Stream:建立连接后通过recv之类的函数来接受客户端发送过来的数据。

 

client:

   ACE_INET_Addr:提供服务器的主机号，端口号以待连接。

   ACE_SOCK_Connector：通过connect方法来建立连接，同时初始化ace_sock_stream.

   ACE_SOCK_Stream:发送数据给指定的服务器。
