针对如今万兆网络流量服务器处理的瓶颈问题，提出了一种基于FPGA的万兆以太网TCP/IP协议处理架构。通过在处理架构中划分控制平面和数据平面，使各个逻辑电路模块的协同操作，并结合高速的I/O处理和存储器处理，利用硬件实现了完整的TCP/IP协议栈，有效的解决了服务器处理万兆网络流量的瓶颈问题。将所提出的架构应用于实际万兆以太网TCP/IP卸载板卡中，其协议支持ARP、ICMP、UDP、TCP等，并且时延最低可达0.288 μs，文件传输速率可达933 MB/s，CPU资源占用率仅为10%，光口有效数据吞吐率可达9.034 Gbps。

这是我自己移植的代码，依照UC/TCP-IP的文件架构。在ARM9 S3C2410上面实现，网卡芯片是，RTL8019AS。并已经成功实现了。PING ，UDP ，TCP都是可行的。UC/TCP-IP并非开源，用于商业，要给钱的。
代码，利用UC/TCP-IP协议栈，实现了一个UDP服务，TCP服务！
UC/TCP-IP移植包括三个部分
1，与CPU的接口。
2，与RTOS的接口。
3，与NIC的接口。
但是，要注意，还有一个BUG，那就是网速快的时候，OVW发生，RTL8019AS重启，重启以后就不再正常工作，不知为何。欢迎交流。。。。

这是一本系统阐述Linux设备驱动程序技术内幕的专业书籍，它的侧重点不是讨论如何在Linux系统下编写设备驱动程序，而是要告诉读者隐藏在这些设备驱动程序背后的那些内核机制及原理。作者通过对Linux内核源码抽丝剥茧般的解读，再辅之以精心设计的大量图片，使读者在阅读完《深入Linux设备驱动程序内核机制》后对驱动程序前台所展现出来的那些行为特点变得豁然开朗。

INTRODUCTION
lwIP is a small independent implementation of the TCP/IP protocol suite.
The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
while still having a full scale TCP. This making lwIP suitable for use
in embedded systems with tens of kilobytes of free RAM and room for
around 40 kilobytes of code ROM.
lwIP was originally developed by Adam Dunkels at the Computer and Networks
Architectures (CNA) lab at the Swedish Institute of Computer Science (SICS)
and is now developed and maintained by a worldwide network of developers.
FEATURES
* IP (Internet Protocol, IPv4 and IPv6) including packet forwarding over
multiple network interfaces
* ICMP (Internet Control Message Protocol) for network maintenance and debugging
* IGMP (Internet Group Management Protocol) for multicast traffic management
* MLD (Multicast listener discovery for IPv6). Aims to be compliant with
RFC 2710. No support for MLDv2
* ND (Neighbor discovery and stateless address autoconfiguration for IPv6).
Aims to be compliant with RFC 4861 (Neighbor discovery) and RFC 4862
(Address autoconfiguration)
* DHCP, AutoIP/APIPA (Zeroconf), ACD (Address Conflict Detection)
and (stateless) DHCPv6
* UDP (User Datagram Protocol) including experimental UDP-lite extensions
* TCP (Transmission Control Protocol) with congestion control, RTT estimation
fast recovery/fast retransmit and sending SACKs
* raw/native API for enhanced performance
* Optional Berkeley-like socket API
* TLS: optional layered TCP ("altcp") for nearly transparent TLS for any
TCP-based protocol (ported to mbedTLS) (see changelog for more info)
* PPPoS and PPPoE (Point-to-point protocol over Serial/Ethernet)
* DNS (Domain name resolver incl. mDNS)
* 6LoWPAN (via IEEE 802.15.4, BLE or ZEP)
APPLICATIONS
* HTTP server with SSI and CGI (HTTPS via altcp)
* SNMPv2c agent with MIB compiler (Simple Network Management Protocol), v3 via altcp
* SNTP (Simple network time protocol)
* NetBIOS name service responder
* MDNS (Multicast DNS) responder
* iPerf server implementation
* MQTT client (TLS support via altcp)

DEVELOPMENT
lwIP has grown into an excellent TCP/IP stack for embedded devices,
and developers using the stack often submit bug fixes, improvements,
and additions to the stack to further increase its usefulness.
Development of lwIP is hosted on Savannah, a central point for
software development, maintenance and distribution. Everyone can
help improve lwIP by use of Savannah's interface, Git and the
mailing list. A core team of developers will commit changes to the
Git source tree.
The lwIP TCP/IP stack is maintained in the 'lwip' Git module and
contributions (such as platform ports) are in the 'contrib' Git module.
See doc/savannah.txt for details on Git server access for users and
developers.
The current Git trees are web-browsable:
http://git.savannah.gnu.org/cgit/lwip.git
http://git.savannah.gnu.org/cgit/lwip/lwip-contrib.git
Submit patches and bugs via the lwIP project page:
http://savannah.nongnu.org/projects/lwip/
Continuous integration builds (GCC, clang):
https://travis-ci.org/lwip-tcpip/lwip
DOCUMENTATION
Self documentation of the source code is regularly extracted from the current
Git sources and is available from this web page:
http://www.nongnu.org/lwip/
Also, there are mailing lists you can subscribe at
http://savannah.nongnu.org/mail/?group=lwip
plus searchable archives:
http://lists.nongnu.org/archive/html/lwip-users/
http://lists.nongnu.org/archive/html/lwip-devel/
There is a wiki about lwIP at
http://lwip.wikia.com/wiki/LwIP_Wiki
You might get questions answered there, but unfortunately, it is not as
well maintained as it should be.
lwIP was originally written by Adam Dunkels:

Reading Adam's papers, the files in docs/, browsing the source code
documentation and browsing the mailing list archives is a good way to
become familiar with the design of lwIP.
