CoDel (Controlled-Delay Active Queue Management) algorithm uses the local minimum queue as a measure of the persistent queue, similarly, it uses a minimum delay parameter as a measure of the standing queue delay. Queue size is calculated using packet residence time in the queue.
Properties
| Property | Description |
| codel-ce-threshold (default: ) | Marks packets above a configured threshold with ECN. |
| codel-ecn (default: no) | An option is used to mark packets instead of dropping them. |
| codel-interval (default: 100ms) | Interval should be set on the order of the worst-case RTT through the bottleneck giving endpoints sufficient time to react. |
| codel-limit (default: 1000) | Queue limit, when the limit is reached, incoming packets are dropped. |
| codel-target (default: 5ms) | Represents an acceptable minimum persistent queue delay. |
FQ-Codel
CoDel - Fair Queuing (FQ) with Controlled Delay (CoDel) uses a randomly determined model to classify incoming packets into different flows and is used to provide a fair share of the bandwidth to all the flows using the queue. Each flow is managed using CoDel queuing discipline which internally uses a FIFO algorithm.

Before sending data over an interface, it is processed by the queue. This sub-menu lists all available interfaces in RouterOS and allows to change queue type for a particular interface. The list is generated automatically.
