流水号在互联网报文传输中的应用

使用流水号实现报文的丢失检测和重发功能是电报网中广泛使用的一种方法。将流水号方法应用到互联网报文传输中。研究了使用流水号方法的基本规则、命令格式、工作流程和应用特点。在设计的公路货运信息系统中应用了流水号方法，结果表明，方法简单容易实现，节省了客户机和服务器的大量时间，基本上实现了设计要求。在对信息完整性要求不是十分严格、网络数据流量较大的系统中可以采用流水号方法实现报文的丢失检测和重发。

Study on application of sequence id in message transport

Sequence id is one of the most popular method in telecom network which is used to check and resend the lost message and packages. The application of sequence id in transportation of message in the Sinternet was studied, and the rules, command format and flow chart using the sequence id were expatiated. Also the characteristics and using limitation of sequence id method were mentioned. We have applied the sequence id method to the information system of highway cargo freight. The operation results showed that the sequence id method is simple and easy to apply, and the application of it can save loads of time for both client and server. It therefore can be used in systems which have larger data flow and less concern for data integration.
