winsock 客户端程序 简单测试来自server端的程序

查邮件服务器邮件信息源代码（支持SOC），很有价值

VC++6编译，UDP组播程序，分为发射端和接收端两个部分，这是接收端程序-VC 6 compiler, UDP Multicast procedures, divided into transmitter and receiver in two parts, which is receiving end procedures

此程序和MTSServer本合使用，MTSServer是服务端程序，该程序很好的说明了网络客户如何通过TCP连接到服务器，并通过密码验证方法传送多个文件-MTSServer this procedure and the use of Hopewell, MTSServer-service procedures, the procedures for a good reminder of how the customer network through TCP connection to the server, and through password verification means of transmission multiple files

1-持续CSMA协议下，当一个用户要发送数据时，它首先侦听信道，看是否有其他站点在传送。如果信道忙，就持续等待直到信道空闲时，便将数据送出。若发生冲突，就等待一个随机长的时间，然后重新侦听。 对于这种协议，先考虑当前帧i时的前一帧时i-1，得到前一帧时的最后一帧frame0（相对时间最大的帧）的相对时间dt0，然后再在当前帧时查看有哪些帧的相对时间会小于dt0，这些帧若是发送就会与frame0发生冲突，所以这些帧就进入持续等待状态，这些帧并没有发送。再考虑当前帧余下的帧（dt > dt0），它们中的第一帧侦听到信道处于空闲状态，所以就发送，而其他的帧由于第一帧的发送又处于等待状态。若有大于或等于2个帧的相对时间相等，且它们又同时侦听到信道空闲时，就会同时发送而导致冲突，冲突发生后的处理方法同上两个协议的一样。 -1- CSMA continued under the agreement, when a user to send data, it first interception Channel to see if there are other sites in transmission. If Channel busy, continuing to wait until the idle channel, and put more information out. If there is conflict, it is a long wait for a random time, then re-interception. Such agreements, to consider the current frame i am one of the former when i-1, be a time before the final one frame0 (relative to the time frame) the relative dt0 time, and then when the current frame to detect what the relative time frame will be less than dt0, these frames will be sent if and frame0 conflict, th

用VC编写的socket小程序，有客户端和服务端，两者3次握手建立连接，用到了最基本的socket，bind，listen，send，receive，函数，非常适合初学者，我就是用这个例子学习的socket编程，很经典的例子有，还有小界面-Socket using a small program written in VC, there are client and server, the two three-way handshake to establish a connection, use the most basic socket, bind, listen, send, receive, function, very suitable for beginners, but I just use this example to learn socket programming, it is the classic case in point, there is a small interface

heritrix是一种开源的网络爬虫/网络蜘蛛，heritrix目的是能够跟踪页面的url进行扩展的抓取，最后为搜索引擎提供广泛的数据来源。-heritrix is an open source network reptiles/Web Spiders, heritrix purpose is to track the page url to the expansion of the crawl, and finally for the search engine provides a wide range of data sources.
