Traffic control aims to control the outgoing traffic of services running on DiskStation. Once you select a service, you need to set up the Guaranteed Bandwidth and Maximum Bandwidth to limit its outgoing traffic.
Guaranteed Bandwidth defines the outgoing traffic this service guarantees to serve when the whole system bandwidth is enough.
Maximum Bandwidth defines the outgoing traffic this service can borrowed when the whole system bandwidth is enough and there is System Remaining Bandwidth. It is suggested that the system manager calculate System Output Bandwidth first and then make sure the sum of Guaranteed Bandwidth for each service is not greater than System Output Bandwidth, or the setting may not work correctly.
Setting Formula:
System Output Bandwidth = Sum of Guaranteed Bandwidth of each service + System Remaining Bandwidth
Guaranteed Bandwidth for each service ≤ Maximum Bandwidth for each service
Note: If the outgoing packets do not match any traffic control rules, the default behavior will be no limitation. You can add your own default traffic control rule at the end of all rules by choosing All ports, and specify Guaranteed Bandwidth and Maximum Bandwidth.
Now you can see the created traffic control rule in the rule list.
