Bufferbloat thus causes problems such as high and variable latency, and choking network bottlenecks for all other flows as the buffer becomes full of the packets of one TCP stream and other packets are then dropped. [6] A bloated buffer has an effect only when this buffer is actually used.
A full implementation of CoDel was realized in May 2012 and made available as open-source software. [3] It was implemented within the Linux kernel (starting with the 3.5 mainline). [9] Dave Täht back-ported CoDel to Linux kernel 3.3 for project CeroWrt, which concerns itself among other things with bufferbloat, [10] where
Co-Founder of the Bufferbloat Project Dave Täht (born August 11, 1965) is an American network engineer , musician, lecturer, asteroid exploration advocate, and Internet activist. He is the chief executive officer of TekLibre.
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.
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 ...
CeroWrt – (2011—2014) project to resolve bufferbloat in home networking, support IPv6, integrate DNSSEC, for wired and wireless, to complement the debloat-testing kernel tree and provide a platform for real-world testing of bufferbloat fixes. [77] The CeroWRT project is completely by 2014, when the finalized fixes were merged into OpenWRT.
In TCP, the congestion window (CWND) is one of the factors that determines the number of bytes that can be sent out at any time. The congestion window is maintained by the sender and is a means of preventing a link between the sender and the receiver from becoming overloaded with too much traffic.
In data communications, the bandwidth-delay product is the product of a data link's capacity (in bits per second) and its round-trip delay time (in seconds). [1] The result, an amount of data measured in bits (or bytes), is equivalent to the maximum amount of data on the network circuit at any given time, i.e., data that has been transmitted but not yet acknowledged.
