RouteOS(MikroTik)流控策略：HTB和PCQ

4 人贊了文章

哈哈，好久沒有寫文章了

做了這麼久的網路，現感覺網路中的流控至關重要，無論在什麼網路中，都需要保證網路業務的正常開展，重要的業務絕不能有高延時，比如：遊戲。反而看起來一些不重要的業務，可以有較高的延時，比如說：下載，視頻

相信大家聽說RouteOS(MikroTik)的HTB和PCQ結合起來一起使用吧。

網路上奇奇怪怪的教程多的很，也都是一些老舊教程，不適用現在高速的網路環境。

也只是一些零星的設置，不能完整的介紹一個綜合程度較高的網路流控解決方案

下面開始正常介紹和綜合網路中零星的知識，還要自己根據心得體會，重新寫出來的HTB和PCQ

廢話不多說，正式開始：

第一：RouteOS路由器重要的標記（Mangle）

針對大小包進行標記標記代碼：

/ip firewall mangleadd action=mark-connection chain=prerouting new-connection-mark=Conn passthrough=yes src-address=192.168.112.2-192.168.112.254add action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-tcp-smaller packet-size=0-256 passthrough=yes protocol=tcpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-tcp-small packet-size=257-512 passthrough=yes protocol=tcpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-tcp-normal packet-size=513-1024 passthrough=yes protocol=tcpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-tcp-big packet-size=1025-65535 passthrough=yes protocol=tcpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-udp-smaller packet-size=0-256 passthrough=yes protocol=udpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-udp-small packet-size=257-512 passthrough=yes protocol=udpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-udp-normal packet-size=513-1024 passthrough=yes protocol=udpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-udp-big packet-size=1025-65535 passthrough=yes protocol=udpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-icmp passthrough=yes protocol=icmpadd action=mark-packet chain=forward connection-mark=Conn disabled=yes dst-port=80 new-packet-mark=pack-upload-web passthrough=yes protocol=tcpadd action=mark-packet chain=forward connection-mark=Conn disabled=yes new-packet-mark=pack-download-web passthrough=yes protocol=tcp src-port=80add action=mark-packet chain=forward connection-mark=Conn disabled=yes dst-port=443 new-packet-mark=pack-upload-web passthrough=yes protocol=tcpadd action=mark-packet chain=forward connection-mark=Conn disabled=yes new-packet-mark=pack-download-web passthrough=yes protocol=tcp src-port=443add action=mark-packet chain=forward connection-mark=Conn dst-port=53 new-packet-mark=pack-upload-dns passthrough=yes protocol=udpadd action=mark-packet chain=forward connection-mark=Conn new-packet-mark=pack-download-dns passthrough=yes protocol=udp src-port=53add action=mark-packet chain=forward connection-mark=Conn content=weixin.qq.com new-packet-mark=pack-important passthrough=yes

此代碼片段重在標記網路中的大小包。

第二，RouteOS路由器流控設置中Queue Tree：

/queue treeadd max-limit=100M name=queue-download parent=bridge1 queue=pcq-download-defaultadd max-limit=10M name=queue-upload parent=pppoe-out1 queue=pcq-upload-defaultadd name=queue-download-icmp packet-mark=pack-icmp parent=queue-download priority=2 queue=pcq-download-defaultadd name=queue-download-tcp parent=queue-download queue=pcq-download-defaultadd name=queue-download-udp parent=queue-download priority=7 queue=pcq-download-defaultadd name=queue-download-tcp-small packet-mark=pack-tcp-small parent=queue-download-tcp priority=4 queue=pcq-download-defaultadd name=queue-download-tcp-normal packet-mark=pack-tcp-normal parent=queue-download-tcp priority=6 queue=pcq-download-defaultadd name=queue-download-tcp-big packet-mark=pack-tcp-big parent=queue-download-tcp queue=pcq-download-defaultadd name=queue-download-udp-small packet-mark=pack-udp-small parent=queue-download-udp priority=3 queue=pcq-download-defaultadd name=queue-download-udp-normal packet-mark=pack-udp-normal parent=queue-download-udp priority=5 queue=pcq-upload-defaultadd name=queue-download-udp-big packet-mark=pack-udp-big parent=queue-download-udp priority=7 queue=pcq-download-defaultadd name=queue-upload-icmp packet-mark=pack-icmp parent=queue-upload priority=2 queue=pcq-upload-defaultadd name=queue-upload-tcp parent=queue-upload queue=pcq-upload-defaultadd name=queue-upload-udp parent=queue-upload priority=7 queue=pcq-upload-defaultadd name=queue-upload-tcp-small packet-mark=pack-tcp-small parent=queue-upload-tcp priority=4 queue=pcq-upload-defaultadd name=queue-upload-tcp-normal packet-mark=pack-tcp-normal parent=queue-upload-tcp priority=6 queue=pcq-upload-defaultadd name=queue-upload-tcp-big packet-mark=pack-tcp-big parent=queue-upload-tcp queue=pcq-upload-defaultadd name=queue-upload-udp-small packet-mark=pack-udp-small parent=queue-upload-udp priority=3 queue=pcq-upload-defaultadd name=queue-upload-udp-normal packet-mark=pack-udp-normal parent=queue-upload-udp priority=5 queue=pcq-upload-defaultadd name=queue-upload-udp-big packet-mark=pack-udp-big parent=queue-upload-udp priority=7 queue=pcq-upload-defaultadd name=queue-download-important packet-mark=pack-important parent=queue-download priority=1 queue=pcq-download-defaultadd name=queue-upload-important packet-mark=pack-important parent=queue-upload priority=1 queue=pcq-upload-defaultadd name=queue-download-dns packet-mark=pack-download-dns parent=queue-download priority=1 queue=pcq-download-defaultadd name=queue-upload-dns packet-mark=pack-upload-dns parent=queue-upload priority=1 queue=pcq-upload-defaultadd name=queue-download-tcp-smaller packet-mark=pack-tcp-smaller parent=queue-download-tcp priority=2 queue=pcq-download-defaultadd name=queue-download-udp-smaller packet-mark=pack-udp-smaller parent=queue-download-udp priority=1 queue=pcq-download-defaultadd name=queue-upload-tcp-smaller packet-mark=pack-tcp-smaller parent=queue-upload-tcp priority=2 queue=pcq-upload-defaultadd name=queue-upload-udp-smaller packet-mark=pack-udp-smaller parent=queue-upload-udp priority=1 queue=pcq-upload-default

建立隊列樹的時候，需要選擇隊列類型，此時需要選擇PCQ

這裡要著重減少PCQ隊列類型，相信官方的文檔還是比較靠譜的。

介紹我的編寫的腳本動態調節PCQ的Rate,限速，這裡我經過實際觀察，發現版本的不一致限速Rate還是差距較大的。

第三，動態調節PCQ的Rate限速。

{:local s [:len [/ip arp find where interface="bridge1"]];:local down [/queue type get value-name=pcq-rate [/queue type find where name="pcq-download-default"] ];:local up [/queue type get value-name=pcq-rate [/queue type find where name="pcq-upload-default"] ];:if ( $s <= 20) do={:local newdown (100000000 - ($s*4000000));:if ( $down != $newdown) do={ /queue type set pcq-rate=$newdown [/queue type find where name="pcq-download-default"];:log warning "已改變PCQ下載限速";}:local newup (10000000 - ($s*400000));:if ( $up != $newup) do={/queue type set pcq-rate=$newup [/queue type find where name="pcq-upload-default"];:log warning "已改變PCQ上傳限速";}}:if ( $s > 20 && $s <= 30) do={:local newdown (20000000 - (($s-20)*800000)); :local newup (2000000 - (($s-20)*80000));:if ( $down != $newdown) do={/queue type set pcq-rate=$newdown [/queue type find where name="pcq-download-default"];:log warning "已改變PCQ下載限速";}:if ( $up != $newup) do={/queue type set pcq-rate=$newup [/queue type find where name="pcq-upload-default"];:log warning "已改變PCQ上傳限速";}}:if ( $s > 30) do={:if ( $down != 8000000 ) do={/queue type set pcq-rate=8000000 [/queue type find where name="pcq-download-default"];:log warning "已改變PCQ下載限速";}:if ( $up != 800000) do={/queue type set pcq-rate=800000 [/queue type find where name="pcq-upload-default"];:log warning "已改變PCQ上傳限速";}}}

此腳本根據ip-arp的在線mac地址動態調節PCQ的Rate限速。

至此，完成了RouteOS對流控策略HTB(大小包)和PCQ(動態調節Rate的限制)

歡迎大家使用該代碼及腳本為自己負責的網路提供更好的網路質量。

本代碼及腳本經過本人半年測試，使用良好，但是也要根據網路做出修改。

如有錯誤，歡迎斧正。
