摘要
嵌入式系统的网络应用需要精简的TCP/IP协议栈的支持,而在有限的存储空间中,重新设计了MBUF结构,并将其组织成链表的形式装载网络报文,采用零拷贝技术在协议栈各层间进行传递,这种简化策略可提高CPU的利用率及节约存储空间的占用,并且可移植性强,具有较高的实用价值.
The network application of the embedded system need the support of the TCP/IP protocol stack. And in the limited storage space,MBUF structure was redesigned. and they was organized into the form of list to load network packet. The zero copy technology is adopted to transmit data among the protocol stack. the simplified strategy can improve the utilization of CPU and save the occupancy of storage space. And the way has portability and high value.
