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

此程序能应用于网络数据之间的传输，既能发送，也能接收，已经调试成功，还算不错-this procedure could be used between network data transmission, can send, receive, debugging has been successful, quite well!

通过设置发送并接收消息：可以设置端口，波特率，奇偶校验等参数.用TCP/IP实现客户/服务器模式.-send and receive news : you can set ports, baud rate, parity and other parameters. Using TCP/IP client/server model.

这是一个简单的JAVA聊天程序，同时能够发送声音。 包括两个部分：服务器端和客户端。 基本功能如下： 服务器端： 向所有客户端发送消息；转发消息；发送声音数据给客户端。 客户端： 显示当前在线用户；向某个用户发送消息；接受服务器端发送过来的声音。 这个程序可能看起来有点乱，因为很久没用JAVA了，但是最近别人要我帮忙写一个，所以就。。。 希望能够起到抛砖引玉的效果。 Feel free and enjoy it!-This is a simple Java Chat procedures, and to transmit sound. Including two parts : the server and client. Basic functions are as follows : Server : to all client send messages; Forward news; To send voice data to the client. Client : Display current online users; A user to send messages; Accept server sent over the voice. This procedure may seem somewhat arbitrary, as long JAVA useless, but others recently wrote to me for help one, So. . . To serve as a trigger effect. Feel free and enjoy it!

以流量统计为主，没有抓底层的mac地址，抓了上层的包，并统计各个端口的数据流量。
