摘　　要：TCP协议固有的三次握手过程(3WHS)和TIME-WAIT状态等特性使其在处理连接持续时间短,通信数据少的连接时效率不高,限制了其在嵌入式系统中的应用。结合嵌入式系统的特点详细分析了这些限制,提出在嵌入式系统中引入T/TCP协议来解决这些问题,并在VxWorks系统中实现了T/TCP协议。实验结表明,T/TCP协议在嵌入式系统中比TCP协议有更好的性能表现。Due to the inherent features such as 3-Way HandShake （3WHS） process and TIME_WAIT state, transmission control protocol （TCP） is not efficient enough in processing connection with short duration and little communication data, which restricts its application in embedded environment. After analyzing these restrictions, we proposed adopting transaction TCP （T/TCP） to solve these restrictions, and then implemented T/TCP in embedded system VxWorks. Experimental result shows that T/TCP has better performance than TCP in embedded system.
