【转】Ether Types

Ether Types (last updated 2008-09-09) NOTE: Please see [RFC5342] for current information and registration procedures. This registry will be revised soon and will be replaced with up-to-date information. Many of the networks of all classes are Ethernets (10Mb) or Experimental Ethernets (3Mb). These systems use a message "type" field in much the same way the ARPANET uses the "link" field. If you need an Ether Type, contact: IEEE Registration Authority IEEE Standards Department 445 Hoes Lane Piscataway, NJ 08854 Phone +1 732 562 3813 Fax: +1 732 562 1571 Email: <ieee-registration-authority& ieee.org > http://standards.ieee.org/regauth/index.html The following list of EtherTypes is contributed unverified information from various sources. Another list of EtherTypes is maintained by Michael A. Patton and is accessible at: <URL: http://www.cavebear.com/CaveBear/Ethernet/ > <URL: ftp://ftp.cavebear.com/pub/Ethernet-codes > Assign...

【转】udp编程实例

UDP通讯实例 2008-04-29 15:30:05 / 个人分类： linux C编程 UDP协议的几点好处： 1.UDP不要求保持一个连接； 2.UDP没有因接收方认可收到数据包（或者当数据包没有正确抵达而自动重传）而带来的开销； 3.设计UDP的目的是用于短应用和控制信息； 4.在一个数据包接一个数据包的基础上，UDP要求的 网络 带宽比TCP更小。 UDP的几个缺点： 1.程序员必须创建代码检测传输错误并进行重传（如果应用程序要求这样做）； 2.程序员必须把大数据包分片。 code： <1> /* * sender.c--UDP protocol example */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <netdb.h> int port = 6789; int main() {     int socket_descrīptor;     int iter = 0;     char buf[80];     struct sockaddr_in address;     /* Initialize socket address structure for Interner Protocols */     bzero(&address, sizeof(address)); // empty data structure     address.sin_family = AF_INET;     address.sin_addr.s_addr = inet_addr("127.0.0.1");     address...
