ROS最正确的限速.doc

ROS最正确的限速-小包优先+带宽均分+简单队列限制上传速度注意：本文针对10M带宽做出的限速说明，请根据自己的实际带宽更改相应的限速设置 = START =一、小包优先的脚本如下：/ip firewall mangleadd chain=forward p2p=all-p2p action=mark-connection new-connection-mark=p2p_conn passthrough=yes comment= disabled=noadd chain=forward connection-mark=p2p_conn action=mark-packet new-packet-mark=p2p passthrough=yes comment= disabled=noadd chain=forward connection-mark=!p2p_conn action=mark-packet new-packet-mark=general passthrough=yes comment= disabled=noadd chain=forward packet-size=32-512 action=mark-packet new-packet-mark=small passthrough=yes comment= disabled=noadd chain=forward packet-size=512-1200 action=mark-packet new-packet-mark=big passthrough=yes comment= disabled=no/ queue treeadd name=p2pW parent=WAN packet-mark=p2p limit-at=400000 queue=default priority=8 max-limit=400000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=noadd name=p2pL parent=LAN packet-mark=p2p limit-at=400000 queue=default priority=8 max-limit=400000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=noadd name=ClassA parent=LAN packet-mark= limit-at=0 queue=default priority=8 max-limit=100000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=noadd name=ClassB parent=ClassA packet-mark= limit-at=0 queue=default priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=noadd name=Leaf1 parent=ClassA packet-mark=general limit-at=0 queue=default priority=7 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=noadd name=Leaf2 parent=ClassB packet-mark=big limit-at=0 queue=default priority=6 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=noadd name=Leaf3 parent=ClassB packet-mark=small limit-at=0 queue=default priority=5 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no 二、然后是带宽均分：这个例子示范了如何将10Mbps下载2Mbps上传，均分给网络10.10.12.0/24中的活动的用户# 所有来自本地网络192.168.0.0/24的流，标记 一个用户标记/ip firewall mangle add chain=forward src-address=192.168.10.0/24 action=mark-connection new-connection-mark=users-con/ip firewall mangle add connection-mark=users-con action=mark-packet new-packet-mark=users chain=forward# 添加两个新的PCQ类型。第一个命名pcq-download，将依据目的地址聚合所有流。我们将给本地接口使用这个queue type。它将为那些目的地址是网络10.10.12.0/24的下载，创建一个动态队列。第二个命名为pcq-upload，将依据源地址聚合所有流。我们将给公网接口使用，所以它将为来自本地网络10.10.12.0/24到internet的上传，创建以一个动态队列/queue type add name=pcq-download kind=pcq pcq-classifier=dst-address/queue type add name=pcq-upload kind=pcq pcq-classifier=src-address# 给下载流创建一个queue tree/ queue treeadd name=Download parent=LAN packet-mark= limit-at=0 queue=default priority=8 max-limit=10000000 burst-limit=0 burst-threshold=0 burst-time=0sadd parent=Download packet-mark=users limit-at=0 queue=pcq-download priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s # 给上传流创建一个queue tree/ queue treeadd name=Upload parent=WAN packet-mark= limit-at=0 queue=default priority=8 max-limit=2000000 burst-limit=0 burst-threshold=0 burst-time=0sadd parent=Upload packet-mark=users limit-at=0 queue=pcq-upload priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s# 注意：如果你的ISP不能提供一个固定的流量，你可以在上传QUEUE规则和下载QUEUE规则中，直接在接口上使用QUEUE/queue tree add parent=LAN queue=pcq-download packet-mark=users/queue tree add parent=WAN queue=pcq-upload packet-mark=users 三、限制上传速度的脚本：:for aaa from 2 to 254 do=
