p-持续CSMA协议下,一个用户在发送之前,先侦听信道,若是空闲,就以概率p发送出去,而以q =1-p的概率推迟到下一帧时。如果下一帧时仍是空闲,便再次以概率p发送而以q推迟到再下一帧时。直到发送成功或另外一用户开始发送时为止。若一开始就侦听到信道忙,它就等到下一帧时,然后再开始上述过程。若发生冲突,这等待一随机时间后重新开始。本实验中取q值为0.5。求的是0.5-持续CSMA。
-p-persistent CSMA agreement, a user before sending the first interception channel, if idle, with probability p sent, and to q = 1-p probability postponed to the next frames. If the next frame was still idle, they again sent with probability p and q to further postponed to the next frames. Until this a success or other users at the beginning of this date. If an interception at the start of the busy channel, it will wait till the next frames, and then begin the process. If conflict breaks out, waiting for a random period of time after the re-start. The experiments take q value of 0.5. For the 0.5-sustained CSMA.

网络的相关知识,网络程序的编写,Socket是连接应用程序与网络驱动程序的桥梁,Socket在应用程序中创建,通过bind与驱动程序建立关系。此后,应用程序送给Socket的数据,由Socket交给驱动程序向网络上发送出去。计算机从网络上收到与该Socket绑定的IP+Port相关的数据后,由驱动程序交给Socket,应用程序便可从该Socket中提取接收到的数据。网络应用程序就是这样通过socket进行数据的发送与接收的。TCP与UDP的工作原理与编写过程,如何在程序中链接库文件。一个字符界面的聊天程序。-network of the knowledge, network program, Socket is a link between the application and network driver bridges, Socket in the application process to create, Driving through bind with the procedures established relations. Since then, Socket applications presented data from the socket to the network driver to send out. Computer network received from the Socket bundled IP Port relevant data, by the driver to Socket, application procedures can Socket from the extraction of data received. Network applications through this is the socket for data transmission and reception. TCP and UDP Principle and the work of preparation, how to process the document link.
