一个网络抓包工具，支持三种协议(TCP,UDP和ICMP)的数据包抓取,使用winsock API编写，可以很方便的扩展自己的程序。可以把每种抓取的协议数据保存到日志记录文件中。抓包速度比较快，以树形列表给与分析，可以查看原始数据包。该程序需要在Windows XP/2000/NT操作系统上，并且有管理员权限。-1 PacketCapture tools to support the three kinds of protocols (TCP, UDP and ICMP) packet capture, using the winsock API write, you can easily expand their programs. Can be saved for each crawl of the protocol data to a log file. Ethereal" s faster, in order to give the analysis of tree list, you can view the original packets. The program requires Windows XP/2000/NT operating system and has administrator privileges.

纯ALOHA协议 在该协议下，用户只要有帧产生，就会传送出去，发生冲突时，就等待一个随机时间后再重发。 所以对当前帧时，只有两种情况下可以发送成功： 1）当前帧时只有一帧要发送，且当前帧时的前一帧时无帧发送； 2）当前帧时只有一帧要发送（发送时刻为t），且前一帧时的最后一帧的发送时间不在（t- FRAMETIME）~ t这段时间内。 其他情况下都会产生冲突。 发生冲突时，错误帧继续传送，用户重新发送帧，设定一个随机数Rt，将该帧添加到第Rt/ FRAMETIME帧时上去，并设该帧的相对时间为Rt% FRAMETIME。这样即相当于用户等待一随机时间后重发。 对每一帧时进行上述控制，最终可得到成功发送的次数Suc，将其除以Suc = Suc /ARRAYLENGTH即得平均每帧时发送成功的帧数。 对于不同G，得到不同FrameArray，所得的Suc也不同，用一个数组来保存G与Suc的对应关系，再将其画出来。 -pure ALOHA agreement under the agreement, as long as users have a frame, it will transmit out, conflict, will wait for a random period of time before re-issued. Therefore, the current frame, there are only two circumstances can this success : 1) the current frame only one to send, and the current frame before one-time frame sent; 2) the current frame only to send a (t this moment), but before a final of a transmission time not (t-FRAMETIME) ~ t this time. Other cases will have conflict. Conflict, to continue to disseminate the wrong frame, users re-sending fram
