嵌入式系统Design and Implementation of the lwIPTCP/IP Stack Swedish Institute of Computer ScienceFebruary20,2001Adam Dunkelsadam@sics.seAbstractlwIP is an implementation of the TCP/IP protocol stack.The focus of the lwIP stack is toreduce memory usage and code size,making lwIP suitable for use in small clients with verylimited resources such as embedded systems.In order to reduce processing and memory demands,lwIP uses a tailor made API that does not require any data copying.This report describes the design and implementation of lwIP.The algorithms and data struc-tures used both in the prot
