Queueing Algorithms
You can apparatus several altered queueing algorithms on Cisco routers. The best accepted blazon is Weighted Fair Queueing (WFQ), which is enabled by absence on low-speed interfaces. There is additionally a class-based adaptation of WFQ alleged Class-based Weighted Fair Queueing (CBWFQ). These algorithms accept the advantage of actuality fast, reliable, and accessible to implement. However, in some cases you ability appetite to accede some of the added queueing systems accessible on Cisco routers.
Priority Queueing lets you specify complete prioritization in your arrangement so that added important packets consistently announce beneath important ones. This can be useful, but it is generally alarming in practice.
The added important queueing algorithm on Cisco routers is Custom Queueing, which allows you absolute ascendancy over abounding of the queueing parameters.
