MikroTik Quality of Service (QoS) can be used to prioritize traffic on your network. This can be useful if you have certain types of traffic that you want to prioritize over others. For example, you may want to prioritize your VoIP traffic over your web browsing traffic.
Mikrotik QoS priority services is a feature that allows you to set up rules to prioritize certain types of traffic over others. This can be useful if you have a limited bandwidth connection and need to ensure that critical traffic, such as VoIP or video conferencing, is given priority over less important traffic, such as email or web browsing.
In conclusion, the Mikrotik QoS priority services can be a great help in managing your network traffic and ensuring that critical services have the bandwidth they need. However, it is important to remember that this is only one part of a complete QoS solution. In order to get the most out of your Mikrotik router, you should also consider using other QoS tools such as traffic shaping and class-based queuing.
