It is necessary to monitor the usage of network resources within the network, and provide the solution in order to avoid network congestion problems. Based on it, a real-time network traffic analysis followed and optimization of the performance benefits. Paper will implement solution of congestion problems with packets, which are processed in RouterOS. This method will combine with mangle, firewall rules, so that we can manage the internet connection to our network ideally, and prioritize the connection packet that we want to get priority in size as we need.
