QOS with Mikrotik

QOS With Mikrotik

Following are few scenarios for some examples :

Post#1 – PCQ base Bandwidth Management with different bandwidth for DAY / NIGHT / DAYS using TIME feature in Mikrotik

Scenario:

We are using Mikrotik CCR1036 ver 6.43.7 , acting as PPPoE NAS, Free-Radius is providing authentication for users account & also its informing NAS about from which POOL users should get IP address , based on the profile. Example 1mb user gets IP from 1mb pool from NAS.

We require following bandwidth plan:

1 mb user bandwidth plan

• From 10am till 5pm > 1mb
• From 5pm till 10am next morning > 2mb
• Saturday + Sunday Full Time > 2mb

in User PPP Profile, I have added following line

This line will remove any Dynamic Queue that will be created by Radius.

Done.

Screenshots …

PCQ base simple Queues with TIME settings, each queue will be enabled as per time

Remove DYNAMIC Queue by Script command

Its useful when you are using PCQ base queueus , and your radius still sends dynamic queues, you can add this in pppoe profile startups script section, so any dynamic queue will be removed whenever any user logins

Post#2 – Limit user traffic using PCQ (also useful for Hotspot Bypassed MAC address)

To limit all users 192.168.1.0/24 to 512kb epr user, using PCQ, use following script.

Change the Bandwidth and Target IP addresses to meet your local requirements.
Bandwidth example:
512k = 524288
1mb = 1048576
2mb = 2097152
4mb = 4194304

Result as showed in the image below . . .

Post#3 – Allowing specific extension Low Priority over other traffic

In this example we are marking traffic via mangle rules. .iso extension is marked as low priority traffic , and all other traffic is marked as hi priority traffic.

For example We have 256kb internet bandwidth in total. and we want that when users are downloading any .iso file, it gets low priority over other traffic i.e browsing etc. Use the following.

▼

4# Allowing Specific File Extensions High / Limited / Unlimited Bandwidth

For example, You have a network and every user have there bandwidth limited at 256kb. Now you want that if a user is downloading .FLV video file , He can view/download it at unlimited speed regardless of his allowed speed limit, i.e 256kb package, Use the following.

First mark all packets with .flv extention.

Now Create a Queue Tree and Set Unlimited or Limited Bandwidth (OR As per your requirements if you want to allot specific amount, set it) to Marked Packets

You can use the same in reverse to limit specific extension type bandwidth usage.

5# Allowing Specific Ports High Priority over other traffic

First we need to mark protocols. (In this example we are using SMTP port 25 )

Now we will create Simple Queue and give high priority to marked packets and other packets low priority. (In this example we have 2Mb WAN connection)

Now SMTP traffic will get higher priority over other traffic.

6# Equal Distribution of Bandwidth for a number of users using PCQ

If you have a 512 kbps WAN connection and you want to share this equally among your users  but if only one pc is active it should have the full 512 kbps, if 2 pcs are active 256 kbps each and vise versa.
As shown in the image below . . .

Use the following:

▼

7# Limiting Single User Bandwidth via Simple QUEUE (Lookout for order number)

▼

8# Simple Queue with BURST

Following simple queue with BURST

– Limit user at 64kb in general.
– When the user will download at full 64kbps speed, he will be able to burst upto 256kb for 5 seconds. after 5 seconds , user will fall to 64kb again for next 5 seconds.

In short 5 seconds on load 256kbps, and next 5 seconds, 64kbp.
