计算机网络第四次作业
计算机网络第四次参考答案4.一大群ALOHA 用户每秒钟产生50个请求，包括原始请求和重传请求。
时间槽单位为40毫秒。
（a ）试问：第一次发送成功的机会是多少？（b ）试问：恰好K 次冲突之后 概率是多少？（c ）试问：所需传输次数的期望值是多少？解：（a ）取G = 2，根据泊松分布公式!]Pr[k e G k Gk -=，可得几率为2-e （b ）k G k G e e 865.0135.0)1(⨯=---（c ）传输次数的期望值：4.7==Ge E6.试问在下列两种情况下CSMA/CD 的竞争时间槽是多少？（a ）一个2千米的双导线电缆（twin-lead cable ）（信号传播速度是信号在真空中传播速度的82%）?（b ）40千米长的多模光纤（信号传播速度是信号在真空中传播速度的65%）？ 解：（a ）信号传播速度在双导线电缆中是s m /1046.28⨯。
则信号在其中传播2km 时间是s μ13.8。
所以, 竞争时间槽是 s μ26.16（b ）信号传播速度在多模光纤中是s m /1095.18⨯。
则信号在其中传播40km 时间是s μ13.205。
所以, 竞争时间槽是 s μ26.4108.在二进制倒计数协议中，试问为什么一个编号较低的站有可能得不到发送数据报的机会。
解：如果编号较高的站和一个编号较低的站同时有数据报要发送，编号较高的站总能优先得到发送的机会。
根据这样的前提，若有编号较高的站点一直持续地发送数据报，那么一个编号较低的站就得不到发送数据报的机会。
