Modelling BBR’s interactions with loss-based congestion control
Guest Post: While BBR is supposed to be a rate-based algorithm, when competing with other flows, BBR is window-limited.

Bufferbloat may be solved, but it’s not over yet
Dave Täht recounted the story of bufferbloat and the deployment challenges ahead.
Sizing the buffer
If buffers are generally good and improve data throughput, then more (or larger) buffers are better, right?
BBR evaluation at a large CDN
Guest Post: Verizon Media shares its experience using BBR to deliver traffic from its caches.
Does TCP keep pace with QUIC?
Guest Post: Researchers have set out to compare the performance of an optimized TCP stack against QUIC.
A quick look at QUIC
Get the backstory on the history and design of QUIC, and what implications it might have on the overall architecture of the Internet Protocol.
It’s time to replace TCP with online-learning congestion control
Guest Post: Performance-oriented Congestion Control (PCC) is a new online learning approach to congestion control that seeks to overcome the limitations of traditional TCP.
BBR patches for higher WiFi throughput and lower queuing delays
Feedback is sought on recent BBR patches that seek to increase throughput for WiFi and lower queuing delays.
How well does ATR actually work?
Additional Truncated Response (ATR) does not completely fix the issue of large responses but it is worth considering if you want a faster DNS service.
Just one QUIC bit
A proposal to add a “spin bit” to the QUIC protocol sparked much debate at IETF 101.
