• 一个 Handler (处理器)
• 两个 Filter (过滤器) - Logging 过滤器和 ProtocolCodec 过滤器
• Nio Datagram Socket

public void initialize() throws IOException {

    // Create an Acceptor
    NioDatagramAcceptor acceptor = new NioDatagramAcceptor();

    // Add Handler
    acceptor.setHandler(new ServerHandler());

    acceptor.getFilterChain().addLast("logging",
                new LoggingFilter());
    acceptor.getFilterChain().addLast("codec",
                new ProtocolCodecFilter(new SNMPCodecFactory()));

    // Create Session Configuration
    DatagramSessionConfig dcfg = acceptor.getSessionConfig();
        dcfg.setReuseAddress(true);
        logger.debug("Starting Server......");
        // Bind and be ready to listen
        acceptor.bind(new InetSocketAddress(DEFAULT_PORT));
        logger.debug("Server listening on "+DEFAULT_PORT);
}

• 设置 IO 处理器
• 创建过滤器并依次添加到过滤器链
• 创建套接字并设置套接字参数
