综合考虑到数据信息量，以及数据传输可靠性，采用在应用层封装可靠性的自定义协议，底层使用适合大数据量传输UDP协议，实现通讯传输效率和可靠性的平衡。实现上使用socket编程，协议设计上采用对数据报文的分帧，传输控制（报文的顺序等），校验，数据的转义，以及服务器/客户端的通讯握手来实现，在协议设计中充分考虑到继承性和扩展性.-Considering the amount of information to the data, and data transmission reliability, with reliability at the application layer package, a custom protocol, the bottom for large data transfers using UDP protocol, to achieve communication efficiency and reliability of the balance transfer. Implementations 使用 socket programming, protocol design used on the data packet framing, transmission control (the order of packets, etc.), calibration, data of the escape, and server/client' s communication handshake to achieve, in the protocol design in full account of inheritance and scalability.
