摘要
为了适应嵌入式应用的要求,提高轻量级协议栈(light weight internet protocol,LWIP)的响应速度和实时性,提出了两种优化方法。第一种优化方法是采用混合TCP-UDP协议,对少量数据的传输采用UDP协议,而对大量数据的传输采用TCP协议;另一种方法是分别定义紧急数据等待队列与普通数据等待队列,只有在所有紧急数据处理完成后,才可以处理普通数据。实例测试表明,这两种优化方法可以提高嵌入式设备的网络性能。
To meet the requirements of embedded applications and improve LWIP（light weight internet protocol） response speed and real-time,two optimization methods are presented.The first method is adopting hybrid TCP-UDP protocol,which used UDP protocol when a small amount of data needed to be transported and used TCP protocol when lots of data needed to be transported.The other method is creating emergency data waiting queue and general data waiting queue.Only when all emergency data had been processed,general data could be processed.Finally,some case tests are presented to prove that these two optimization methods improve the network per-formance of embedded devices.
