摘要
在PDA(个人数字助理)中浏览器的设计中,由于无线网络延迟大、带宽窄,所以基于TCP协议的HTTP应用并不是理想的传输协议。但使用UDP作为短会话时的传输层协议,而对于有大量数据需要传输时则使用TCP作为传输层的协议,这样的混合协议可以很好的解决数据传输的问题。
In the browser＇s design from PDA （personal digital assistants）, since the big delay and narrow bandwidth in wireless network,so HTTP applications that based on TCP protocol is not the ideal transport protocol. However, UDP can be used as the transport layer protocol in short conversation,while,if there are mass data needed to be transmitted, TCP can be adopted as transport layer protocol,this kind of hybrid protocol can give good solution for data transmission problems.
