前言：
PCQ限速对于某些带宽不是很足的网吧来说，确实有点问题，必须你网吧只有15M的光纤，如果你做PCQ限速2M吧（我想2M对于100台机器来说的网吧已经是最大限度了），PCQ开启设置为14M吧，关闭设置为6M！如果有一个人用讯雷下载东西的话。网吧15马上占满，PCQ就会开启，但一旦开启后。你网速就会变到6M以下，那么PCQ就在那里不停的关闭和开启了，这样不单达不到智能限速的效果。还会增加ROS软路由的负担！CPU占用。。所以我就一直想把智能和普通限速做在一起，让讯雷或者其他下载不会乱触发PCQ的流量，但最终还是失败了！启发，我想出了一个既可以动态限速，也可以静态限速的方法！例如，还是15M的光纤，100台机器的网吧。我静态设置为3M，这样的话，正常来说。4个人下载东西的话，也只占12M，那么还剩3M，足够其他玩Q和打网游的机器了！
但如果5个人下载的话？怎么办？带宽马上到了15M了。呵呵，那其他玩网游的肯定会卡死！
不用怕，我智能设置为大于14M触发另一个脚本，脚本的内容大概就是关闭原来的3M静态限速，开启1.5M的静态限速，这样一算，1.5*5=7.5M了，再加上玩网游的人，基本上就稳定在10M左右了！
然后再设置一个脚本，当总流量少于6M的话（也就算没那么多人下载了，流量下来了）那么1.5M的静态限速脚本就会自动关闭，又打开了本来3M的限速了！
基本上原理就是这样。通过这个原理，网吧宽带利用就会越来越合理！

上面是完整脚本，直接把每一段复制进去就可以了。需要修改的看下面的说明！
下面是注释：
15M为例 静态是3M，达到14.8M后启用动态是1.5M！
:for aaa from 1 to 254 do={/queue simple add name=(PC . $aaa) dst-address=(192.168.0. . $aaa) limit-at=500000/500000 max-limit=3000000/3000000}
这个是建立静态限速，1to254 改为你内网的IP！比如 2 to 120！ 192.168.0. 这里改为你的IP段！ limit-at=500000/500000 是平均网速500K，max-limit=3000000/3000000 是普通限速3M！
注意一下，这里，包括很多高手都把ROS软路由的算法搞错了，在这里我纠正一下，ROS软路由不是1KB=8Kbit！
而是 1000=1K 1000000=1M
/ ip firewall mangle
add chain=prerouting action=mark-packet new-packet-mark=all-mark

这个是固定脚本！

add name="PCQ-down" kind=pcq pcq-rate=1500000 pcq-limit=50
pcq-classifier=dst-address pcq-total-limit=2000
这里把1500000改为你动态限速时的全网上传速度和下载速度！其他不要改！这里是1.5M！

queue=PCQ-up/PCQ-down limit-at=0/0 max-limit=15000000/15000000
total-queue=default-small disabled=yes
到这里就是建立动态限速的策略了！192.168.0.0/24 改为你IP段！max-limit=15000000/15000000 这里是你总宽带，电信给你多少就填多少！其他不用改，，因为需要转跳到上面的！
/ system script
add name="PCQON"source=":if ([ /queue sim get [/queue sim find

policy=ftp,reboot,read,write,policy,test,winbox,password
add name="PCQOFF"source=":if ([ /queue sim get [/queue sim find
name="PCQ"] disable ]=false ) do={/queue sim disable PCQ}"
policy=ftp,reboot,read,write,policy,test,winbox,password
这个是启发脚本，就是启发动态和关闭动态的脚本！直接复制！
/ tool traffic-monitor
add name="PCQON" interface=WAN traffic=received trigger=above
threshold=14800000 on-event=PCQON comment="" disabled=no
add name="PCQOFF" interface=WAN traffic=received trigger=below
threshold=5000000 on-event=PCQOFF comment="" disabled=no
这个是流量监控，我有15M设置是14.8M启发，足够了。不会延时或者怎么的，不建议改得太少。threshold=5000000是少于5M时关闭动态！这个自己掌握好！多试试！
另外注意的是！interface=WAN 把WAN改成你外网的网卡！
上面的每一段都需要，少一段这个脚本就不完整！不然没效果不要说我！
时间段来启发脚本，只需要改最后一段就OK了！
======================================================
/system scheduler add name=timeon interval=24h start-time=08:00:00 on-event={PCQON} disabled=no
/system scheduler add name=timeoff interval=24h start-time=23:59:59 on-event={PCQOFF} disabled=no
==============================================================
把最后一段替换成这段就是由时间段控制开关PCQ了！
