• channel = channelFactory.newChannel(); // NioServerSocketChannel
• 當channel創建時候同時創建channelPipeline

// AbstractChannel
/**
  * Creates a new instance.
  *
  * @param parent
  *        the parent of this channel. {@code null} if there's no parent.
  */
protected AbstractChannel(Channel parent) {
    this.parent = parent;
    id = newId();
    unsafe = newUnsafe();
    pipeline = newChannelPipeline();
}
