Description: This a basic multi-threaded ping utility using a raw socket. Take a look at the screenshot for the feature list. This code is not 100％ mine. It was adapted from code on the internet (Found in several places so not sure of the author). It has been modified alot though.

Description: 移植到嵌入式系统的TCPIP协议源码，源码内有详细中文注解。
已实现的功能：
支持TCP, UDP, IP, ICMP, ARP, ETHERNET等协议；兼容BSD标准的Socket API接口函数库；ICMP实现PING的功能和UDP无效端口返回；支持TCP的流控制和超时重传；支持TCP主动连接和被动连接； 支持在多任务中建立多个不同的TCP连接，支持各连接同时收发数据； 提供WebSever和UDP服务器范例。
还没实现功能：
IP报的处理不支持分段 在多个网络接口的应用是两个网络间的最大报大小要基本相等。 ICMP协议还不是非常完整 目前ICMP协议只支持PING的功能和UDP无效端口返回。 TCP协议不支持紧急数据 这一版本的ZLG/IP不对TCP传输中的紧急数据报进行处理。 不支持IGMP协议 这一版本的ZLG/IP不支持IP组播和广播。 不支持Socket API发送函数发送大于PMTU 用Socket API发送函数发送数据时，数据长度不可大于一个TCP或UDP报有效数据的长度。

Description: 本文件介绍了一个TCP/IP的功能，设计要点，本协议栈实现的组件包括ARP，I CMP（PING），UDP，TCP。并设计了一个与SOCKET API兼容的标准接口。
TCP/IP协议栈背景
TCP/IP是使用最为广泛的INTERNET通信协议，几乎所有的桌面操作系统如Windows，Redhat Linux都支持TCP/IP协议。为了实现嵌入式系统与PC机的组网通信，就必须在嵌入式系统上实现复杂的TCP/IP协议栈，通过实现了TCP/IP协议栈，就可以方便的实现嵌入式系统与主流桌面操作系统的通信和资源共享，这也是作者编写TCP/IP协议栈的由衷。

Description: 嵌入式TCP/IP协议栈说明书下载--
技术说明：
1)用户应用协议栈则需要编写以太网的数据报收发驱动，就可以使用协议栈提供的标准SOCKET API，完成服务器和客户端应用程序的开发。
2)协议栈运行于非操作系统的环境下，因此它的运行速度与一般采用多任务操作系统的TCP/IP协议，速度相对说来要快。
3)协议栈完成的功能包括ARP，IP，ICMP（ping），TCP，UDP，暂不支持IGMP，RARP。
4)协议栈采用C代码编写，可方便的移植于各种单片机平台。
5)协议栈在ARM7+RTL8019硬件环境下测试，并建立了FTP服务器和WEB服务器，性能稳定。
6)协议栈建立的FTP服务器和WEB服务器与Internet Explorer浏览器和ftp.exe相互兼容。
7)协议栈每一个SOCKET上建了数据缓冲队列(数据结构)，用于接收SOCKET的并发数据，实现多SOCKET的并发数据报处理，可同时运行FTP服务器和WEB服务器。
8)协议栈实现了ACK的延时答应（200ms），支持TCP多包发送和接收，但未支持TCP数据报的失序处理，因此适合局域网内使用。
