ISP Bandwidth Control with MikroTik PCQ

There is no doubt if I may ask some more ISP’s And IT experts, that MikroTik is an excellent router for managing ISP or local ISP Bandwidth. 

  This is one of the reasons, most of the ISPs are now using MikroTik router for managing their client bandwidth. 
There are various types of queue services in MikroTik router for managing internet bandwidth. Among them is PCQ.
PCQ can specially be used for maintaining ISP or local ISP bandwidth. For such reason, in this article I will show how to maintain ISP or local ISP Bandwidth with MikroTik PCQ service.

A brief Introduction To MikroTik PCQ Service
PCQ simply means Per Connection Queues. This service helps to maintain ISP or local ISP Bandwidth so easily. As a network administrator of any ISP company, you are in position to manage various offered bandwidth packages like 512kbps connection, 1Mbps connection or 2Mbps connection for most of your clients out there.

You will agree with me that Managing these packages with MikroTik Simple Queues will be so hardy and time killing. So then we think of a simple way of managing these queues.. and then we have the PCQ concept.

Mikrotik PCQ feature will be so helpful for managing these bandwidth packages because in PCQ service you will just create different PCQ profile according to your bandwidth packages and assign any PCQ profile to a network block.
Then, every IP of this block will get equal bandwidth that you assigned in PCQ Profile. So, your MikroTik Queue configuration is just one time. You will map network block according to your offered bandwidth packages and then assign client IP according to their purchase bandwidth.
PCQ is a simple but effective and hassle free method for managing your ISP bandwidth. Say, you have three offered packages for your ISP clients. These are 512kbps connection, 1Mbps connection and 2Mbps connection. So, your proposed plan would be like below.

512kbps clients will get block IP.
1Mbps clients will get block IP and
2Mbps clients will get block IP.
Now if a client purchases 512kbps connection, you will just assign him/her a block IP or if a client purchases 1Mbps connection, you will assign him/her a block IP. If you configure PCQ in your MikroTik router properly, every client of these blocks will get your assigned bandwidth because in PCQ service every client gets equal bandwidth that will be assigned for the whole block.
Complete PCQ configuration with MikroTik router can be divided into two steps.
