5大IO模型之二：overlap模型，介绍overlap网络io的一般流程。

点量BT的开发目的是让用户无需关心和了解BT的具体实现细节，只需要写几十行甚至几行代码，便可以实现一个功能完善而且强大的BT应用软件。目前点量BT已经在多家客户的网吧游戏更新系统 / 教育视频BT下载系统中应用. 点量BT源码使用高效的c++代码编写，提供标准的动态链接库（DLL），可供C/C++、Delphi、C#、Java、VB等语言和各常用开发环境调用，让您完全像调用系统API一样的调用 -BT point volume was developed to allow users without concern for and understanding of BT specific implementation details, just to write dozens of lines and even a few lines of code, they can realize a fully functional and powerful application software BT. BT has been present at the volume of customers in the Internet cafe to update the game system/education video download BT System. Point the volume of efficient use of BT source c++ Coding, provides a standard dynamic-link library (DLL), available C/C++, Delphi, C#, Java, VB and other language and the common development environment called, allows you to completely the same as calling the system call API

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

Ping 是Windows系列自带的一个可执行命令。利用它可以检查网络是否能够连通，用好它可以很好地帮助我们分析判定网络故障。应用格式：Ping IP地址。该命令还可以加许多参数使用，具体是键入Ping按回车即可看到详细说明。 -ping program
