| 摘 要： | 为了在中小型的嵌入式系统中实现TCP/IP协议栈,要求提供一种有效、简洁、可靠的缓冲区管理。Mbuf是TCP/IP缓冲区管理最广泛的实现方式。该文介绍了简化的Mbuf实现方法,其代码规模只有4.4BSD-Lite的三分之一。该实现方式基于单次拷贝技术,假设基于裸机实现,即没有操作系统的支持。除了提供Mbuf的例程,还实现了Mbuf的动态分配与回收。同时该文简要地总结了目前TCP/IP缓冲区管理的主要方式和新的发展。

| Abstract: | Mbuf is the most popular solution in the implementation of TCP/IP buffer management.This paper describes an efficient and simplified scheme for TCP/IP buffer management which is based on small-size embedded system.In this way,the Mbuf code size is as small as one third of the4.4BSD-Lite.The implementation is also“Single-copy”.The paper then describes the Mbuf routines and structures,and explains how to implement the dynamic allocation and collection.This implementation is based on the bare machine,where doesn't need the support of any OS.This paper briefly overviews the solution and progress of the buffer management of TCP/IP protocol stack. |
