In this case statement works right also if we indicate only one of parameters: "target=" or "dst=", because both of these define where and for which traffic this queue will be implemented.įlags: X - disabled, I - invalid, D - dynamicĠ name="private" target=10.1.1.0/24 dst-address=0.0.0.0/0 Shaping (scheduling) of bidirectional traffic (one limit for the total of upload + download)Īssume we have network topology like Figure 8.6 and we want to limited download and upload for private network (upload - 256kbps, and download – 512kbps).Īdd a simple queue rule, which will limit the download traffic to 512kbps and upload to 256kbps for the network 10.1.1.0/24, served by the interface /queue simple> add name=private target=10.1.1.0/24 max-limit=256K/512K dst=ether2.Using multiple packet marks from /ip firewall mangle.Applying queue rules on chosen time intervals.You can also use simple queues to build advanced QoS applications. The simplest way to limit data rate for specific IP addresses and/or subnets is to use simple queues. MIR (Maximum Information Rate) – ( max-limit in RouterOS) best case scenario, maximum available data rate for flow, if there is free any part of bandwidth.At any given time, the bandwidth should not fall below this committed rate. CIR (Committed Information Rate) – ( limit-at in RouterOS) worst case scenario, flow will get this amount of traffic rate regardless of other traffic flows.If there is no more space in the queue buffer, packets are dropped.įor each queue we can define two rate limits: In another case, traffic exceeds a specific rate and is delayed in a queue and transmitted later when it is possible, but note that the packet can be delayed only until the queue is not full. Next figure explains difference between rate limiting and rate equalizing:Īs you can see in the first case all traffic exceeds a specific rate and is dropped. delay packets that exceed specific rate limit in queue and transmit its when it is possible – rate equalizing (scheduler) ''(100% rate equalizing when queue-size=unlimited).discard all packets that exceed rate limit – rate limiting (dropper or shaper) (100% rate limiter when queue-size=0).Rate limiting can be performed in two ways: Traffic which rate that is less than or equal to the specified rate is sent, whereas traffic that exceeds the rate is dropped or delayed. Rate limiting is used to control the rate of traffic flow sent or received on a network interface. Requires marked packet flows from /ip firewall mangle facility. /queue tree menu - for implementing advanced queuing tasks (such as global prioritization policy, user group limitations)./queue simple menu - designed to ease configuration of simple, everyday queuing tasks (such as single client upload/download limitation, p2p traffic limitation, etc.).There are two different ways how to configure queues in RouterOS: In RouterOS, these hierarchical structures can be attached at two different places, packet flow diagram illustrate both Input and Postrouting chains. HTB allows to create hierarchical queue structure and determine relations between queues. Queue implementation in MikroTik RouterOS is based on Hierarchical Token Bucket (HTB). share available traffic among users equally, or depending on the load of the channel.configure traffic bursts for faster web browsing.
