数据的编码采用了曼彻斯特编码格式,每帧数据包括同步头、有效数据位和冗余校验位三部分。
Manchester code was used in data coding, each frame of data included synchronous head, valid data bits and cyclic redundancy parity bits.
现在开始每条消息头解释消息将包含多少数据,和一个校验和。
Now start every message with a header explaining how much data the message will contain, and a checksum.
然而IP协议本身是不安全的,它只用16比特的校验和来验证IP报文头的完整性。
But IP protocol is not secure, there is only a 16 bits checksum in IP header to validate data integrity.
