Abstract: For the demand of distance laboratory test data transmission in real time and synchronization, based on the diversity of data sources of distance laboratory system, a new network protocol which is based on session is presented. The Distance Laboratory Session Protocol(DLSP), which is based on TCP/IP, through virtual channel multiplexing, and the concept of session is introduced. A criterion to the test host of network communication efficient is given. The result of test shows that good effect and synchronization is archived in data transmission in real time, due to DLSP.

Key words: distance laboratory, TCP/IP, Distance Laboratory Session Protocol(DLSP)

摘要： 针对远程实验室数据传输同步性、实时性的需求，根据远程实验信源的多样性特征，提出一个新的基于事务的网络通信协议DLSP。该协议以TCP/IP协议为基础，采用虚拟信道复用技术，并引入事务的概念，建立了实验主机间应用层高效通信的一种规范。实验表明，使用DLSP协议，在数据传输的实时性、同步性和传输效率方面均取得了较好的效果。
