[Software Engineering] Embbeded_tcp_ip_user_guide DL : 0: 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。诚邀与您合作，QQ：292942278-err

[Software Engineering] sniffer DL : 1: 一、实现 Sniffer 的基本功能。 Sniffer 是一种用于监测网络性能、使用情况的工具。  能够指定需要侦听的网卡（考虑一台机器上多张网卡的情况）  能够侦听所有进出本主机的数据包，解析显示数据包（ ICMP 、 IP 、 TCP 、 UDP 等）各个字段。比如，对 IP 头而言，需要显示版本、头长度、服务类型、数据包长度、标识、 DF/MF 标志、段内偏移、生存期、协议类型、源目的 IP 地址、选项内容、数据内容。要求显示数据的实际含义（例如用 ASCII 表示）；  能够侦听来源于指定 IP 地址的数据包，能够侦听指定目的 IP 地址的数据包，显示接收到的 TCP 和 UDP 数据包的全部实际内容。需要考虑一个 TCP 或 UDP 包划分为多个 IP 包传输的情况；  能够根据指定的协议类型来过虑包，例如，只侦听 ICMP 包，或只侦听 ICMP 和 UDP 包。  功能验证手段：在运行 Sniffer 的同时，执行标准的 Ping 、 Telnet 和浏览网页等操作，检查 Sniffier 能否返回预期的结果。 Windows 平台上可以用 winpcap 类库；在 linux 平台上可以使用 libpcap 类库。也可以调用 Sockets 等有关的网络类库。 -First, the realization of the basic functions of Sniffer. Sniffer is a network for monitoring performance, the use of tools.  listening to the specified needs of the card (taking on a machine more than the case of card)  listening to all incoming and outgoing packets of the host, analysis shows that packet (ICMP, IP, TCP, UDP, etc.) in various fields. For example, the first of the IP, the need to show the version of the first length, service type, packet length, logo, DF/MF logo, paragraph migration, survival, protocol type, source IP address of the purpose, options, content, data内容. Requirement to demonstrate the actual meaning of data (such as that used ASCII)  listening to the specified IP address from data packet to specify the purpose of listening packet IP addresses, indicating the received TCP and UDP packets all the actual content. Need to consider a TCP or UDP packet is divided into a number of IP packet transmission of the situation 

[Software Engineering] W5500 Datasheet DL : 0: The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY embedded. WIZnet‘s Hardwired TCP/IP is the market-proven technology that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. W5500 embeds the 32Kbyte internal memory buffer for the Ethernet packet processing. If you use W5500, you can implement the Ethernet application just by adding the simple socket program. It’s faster and easier way rather than using any other Embedded Ethernet solution. Users can use 8 independent hardware sockets simultaneously. SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5500’s SPI supports 80 MHz speed and new efficient SPI protocol for the high speed network communication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and power down mode.
