Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets. Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput .

FQ-CoDel is published as RFC8290. It is written by T. Hoeiland-Joergensen, P. McKenney, D. Täht, J. Gettys, and E. Dumazet, all members of the "bufferbloat project". [17] Common Applications Kept Enhanced (CAKE; sch_cake in Linux code) is a combined traffic shaper and AQM algorithm presented by the bufferbloat project in 2018.
Gettys was the co-founder of the group investigating bufferbloat and the effect it has on the performance of the Internet. [4] He was a core member of the group from 2010 to 2017, concluding with his publication of "The Blind Man and the Elephant", [ 5 ] calling for the wide adoption of fair queuing and active queue management techniques across ...
Bufferbloat is a phenomenon in packet-switched networks in which excess buffering of packets causes high latency and packet delay variation. Bufferbloat can be addressed by a network scheduler that strategically discards packets to avoid an unnecessarily high buffering backlog. Examples include CoDel, FQ-CoDel and random early detection.
In routers and switches, active queue management (AQM) is the policy of dropping packets inside a buffer associated with a network interface controller (NIC) before that buffer becomes full, often with the goal of reducing network congestion or improving end-to-end latency.
It is true, that when you have bufferbloat, reducing the buffer size reduces the negative impact, but in practice there is no such thing as the optimal buffer size. The right buffer size always depends on the transmission rate, however usually you have multiple destinations with differing transmission rates, making it rather difficult to find ...
