编程实现一个4维的立方体网络仿真,网络节点按照如下方式运行,实验要求:1.网络节点按照默认的顺序,如节点标识0,1,…,15从小到大的顺序依次产生一个数据包。
2.节点产生(或接收到)一个数据包后,随机选择一个相邻节点发送数据包,依此规则重复执行,直至产生数据包的节点接收到自己的数据包后,直接删除该数据包。
超级立方体网络指具有d个维度的网络具有2d个网络节点,网络节点按照0,1,2,…2d-1顺序进行编号。
标识i的节点采用二进制方式可表示为d位的二进制序列,网络任意两个节点二进制方式表示的d位标识符,对应位只有某一位不同时,表示节点是直接相邻接,否则,两个节点之间不存在直接相邻接。
例如,对于一个3维的超级立方体网络,网络中存在8(8=23)个网络节点,如0(000),1(001),2(010),3(011),4(100),5(101),6(110),7(111)。
网络拓扑结构按照如下方式连接,节点0(000)与节点1(001),2(010),4(100)直接相临接,因节点0(000)与节点1,2,4分别在第1位,第2位,第3位不同(从左往右数),其他节点按此规律相邻接。

原贴http://www.right.com.cn/forum/thread-91571-1-1.html20120905版4M固件:1.720N固件,基于703N修改。
TP-Link原厂固件请刷factory,已经是OpenWrt了就刷sysupgrade。
且刷此固件后可直刷OpenWrt703N、OpenWrt720N、TP-Link703N、TP-Link720N固件,不用改固件头。
2.4M固件,当然8M的flash也可以刷。
3.支持MentoHUST(锐捷认证)、3G、NAS(仅支持ext4,不支持ntfs)、共享手机网络、MWAN2负载均衡、打印服务器、远程唤醒、81873070、瑞银网卡,剩余200多K空间,具体见截图。
因试过4M空间集成脱机、NAS等有难度,故不再出4M的脱机固件,请用extroot扩展后自行安装。
4.MentoHUST没有条件测试,如不能自动获取IP,请把Web界面的DHCPscript的值由“udhcpc-i”改成“udhcpc-renew”试试。
5.关于extroot(既用U盘引导系统),没想到现在这么简单了。
简单说下:先把U盘在电脑里格式化成ext3或ext4。
插上U盘,命令行运行blkid得到U盘的UUID值,复制到管理界面的相应UUID,挂载选项“rw,sync”删掉后面的umask=000。
然后勾上extroot和启用,文件系统选对应的ext3或ext4,保存应用OK。
重启下,看看剩余空间大了没,呵呵。
(umask=000只是为了让samba可写而加的参数。
挂载USB存储设备时,如果不用samba请删之。
)6.按住reset键30秒后led闪烁,60秒之前松开reset键则恢复出厂设置。
7.LAN/WAN两个网口正常。
8.默认开启WiFi,无密码。
9.支持模式切换开关,定义如下:AP:开启共享手机网络、开启无线3G:关闭共享手机网络、开启无线Router:关闭共享手机网络、关闭无线10.解释下共享手机网络,OpenWrt官方称为USBTethering,指openwrt路由器通过USB连接智能手机,而智能手机的网络共享给openwrt使用。
目前固件只支持Android系统共享网络功能,而支持iPhone需要集成的软件太多,空间有限,如果出8M固件再考虑吧。
Android本来就支持WiFi热点,可能有点画蛇添足吧,呵呵。
我是偶然发现openwrt还支持这个功能,所以就研究了下,也许在某些情况下这个功能还是有用的吧。
使用方法:a.路由器模式开关切换至AP位置。
b.用USB线连接路由器与手机。
c.手机USB连接管理里面,选择除了“内存卡读取”的其他模式,比如:选择“仅充电”;
然后在“设置”--“系统”里面找到“共享手机网络”,开启“USB绑定”就好了。
回到openwrt界面,会发现有个usb0的接口,已经自动获取了IP,这样openwrt就能使用手机的网络了。
11.关于MWAN2负载均衡,效率还不错,还支持基于session的负载均衡,使用方法见/etc/config/mwan2里面的注释。
mwan2的作者新出了mwan3,有兴味可以去看看:https://forum.openwrt.org/viewtopic.php?id=3905212.703n可刷本固件,但是刷完后lan口不能用。
需先用无线连接,然后编辑/etc/config/network,删除其中wan口配置,把lan的eth0改成eth1后,lan就可以用了。
如703n原厂固件web界面请刷factory,且需要先把固件标识改成07030101才能刷。
13.再说下打印服务器,没有测试,不知道这个版本能不能用,但20120803版有人试过可用,有需求请自行下载。
trunk就是不稳定啊,没办法~~

数帅UIS1000网络硬盘下载器随机光盘,包含各版本ROM数帅公司已经不存在了,官网打不开,但是UIS1000还能正常使用,包括2.000.200版本的迅雷近程下载目前也正常工作。
但是如果硬盘格式化了、换硬盘了,就必须重新初始化、需要随机光盘的初始化工具和ROM2.000.123版本及之前的版本,用初始化工具刷机,2.000.200版本带迅雷近程下载,需要先升级到2.000.123之后,用WEB页面的系统升级来升级。
2.000.200不支持初始化工具直接升级。

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
