动态（平均）分配流量

PCQ ExamplesFrom MikroTik Wiki
Jump to: navigation, search
Per Connection Queue (PCQ) is a queuing discipline that can be used to dynamically equalize or shape traffic for multiple users, using little administration.
[edit] Equal Bandwidth for a Number of Users Use PCQ type queue when you need to equalize the bandwidth for a number of users. We will set the 64kbps download and 32kbps upload limits.

There are two ways how to make this: using mangle and queue trees, or, using simple queues.
1. Mark all packets with packet-mark all:
/ip firewall mangle add chain=prerouting action=mark-packet new-packet-mark=all passthrough=no
2. Setup two PCQ queue types - one for download and one for upload. dst-address is classifier for user's download traffic, src-address for upload traffic:
/queue type add name="PCQ_download" kind=pcq pcq-rate=64000 pcq-classifier=dst-address/queue type add name="PCQ_upload" kind=pcq pcq-rate=32000 pcq-classifier=src-address
3. Finally, two queue rules are required, one for download and one for upload:
/queue tree add parent=global-in queue=PCQ_download packet-mark=all/queue tree add parent=global-out queue=PCQ_upload packet-mark=allIf you don't like using mangle and queue trees, you can skip step 1, do step 2, and step 3 would be to create one simple queue as shown here:
/queue simple add queue=PCQ_upload/PCQ_download target-addresses=192.168.0.0/24That's it!!!

PCQ的两种使用方法:
1、使用queue tree
/ip firewall mangle add chain=prerouting action=mark-packet new-packet-mark=all passthrough=no
/queue type add name="PCQ_download" kind=pcq pcq-rate=64000 pcq-classifier=dst-address
/queue type add name="PCQ_upload" kind=pcq pcq-rate=32000 pcq-classifier=src-address
/queue tree add parent=global-in queue=PCQ_download packet-mark=all
/queue tree add parent=global-out queue=PCQ_upload packet-mark=all
2、使用queue simple

/queue type add name="PCQ_download" kind=pcq pcq-rate=64000 pcq-classifier=dst-address
/queue type add name="PCQ_upload" kind=pcq pcq-rate=32000 pcq-classifier=src-address
/queue simple add queue=PCQ_upload/PCQ_download target-addresses=192.168.0.0/24

这两种方法成都网页上推荐的是第二种吧，有高手说说他们之间的区别吗？

我也概念不清淅，帮你顶顶

这个为什么说是动态分配啊。。看起来像是给某个网段固定速率的

专卖精品 发表于 2007-8-20 13:24:36

PCQ是根据源地址或者目标地址来进行分组的一种限速，比如，限制上行带宽的时候，内网的IP地址就是所有数据包的源地址，这样，ROS就把所有要出去的数据包收集起来，按照源地址进行分组，比如有10个源地址，那就分10个组（翻译的时候应该叫队列），每个组的上行速度是相同的，所以就是平均分配带宽了！

至于动态的意思，就象上面举例的那样，这个时候是10个源地址，一共是100K的带宽，那大家分的10K的带宽，而下个时候只有5个源地址了，那就每家多分了10K，也就是20K的带宽了

若要动态，只要改成
/queue type add name="PCQ_download" kind=pcq pcq-classifier=dst-address
/queue type add name="PCQ_upload" kind=pcq pcq-classifier=src-address

即可

晕倒，不论哪种方法。。。。前提必须添加
/queue type add name="PCQ_download" kind=pcq pcq-classifier=dst-address
/queue type add name="PCQ_upload" kind=pcq pcq-classifier=src-address

看了眼晕,不知道什么时候能学会.
