CoDel (Controlled Delay; pronounced "coddle") is an active queue management (AQM) algorithm in network routing, developed by Van Jacobson and Kathleen Nichols and published as RFC8289. [1] It is designed to overcome bufferbloat in networking hardware , such as routers , by setting limits on the delay network packets experience as they pass ...
The network scheduler logic decides which network packet to forward next. The network scheduler is associated with a queuing system, storing the network packets temporarily until they are transmitted. Systems may have a single or multiple queues in which case each may hold the packets of one flow, classification, or priority.
Fair queuing uses one queue per packet flow and services them in rotation, such that each flow can "obtain an equal fraction of the resources". [1] [2]The advantage over conventional first in first out (FIFO) or priority queuing is that a high-data-rate flow, consisting of large packets or many data packets, cannot take more than its fair share of the link capacity.

An active queue management and denial-of-Service (AQM&DoS) simulation platform is established based on the NS-2 simulation code of the RRED algorithm. The AQM&DoS simulation platform can simulate a variety of DoS attacks (Distributed DoS, Spoofing DoS, Low-rate DoS, etc.) and AQM algorithms (RED, RRED , SFB, etc.).
A Blue queue maintains a drop/mark probability p, and drops/marks packets with probability p as they enter the queue. Whenever the queue overflows, p is increased by a small constant p i, and whenever the queue is empty, p is decreased by a constant p d < p i.
Miami-Dade County and county school district leaders on Thursday announced a plan to build a number of homes on school campuses that will be rented at affordable prices to qualifying teachers and ...
[1] Since WFQ implementation is similar to fair queuing, it has the same O(log(n)) complexity, where n is the number of flows. This complexity comes from the need to select the queue with the smallest virtual finish time each time a packet is sent. After WFQ, several other implementations of GPS have been defined.
