WebWith the increase of diversity in application needs and networks, existing congestion control algorithms (CCAs) do not accommodate this complicated reality. Previous classic CCAs are designed for a specific domain with fixed rules, failing to adapt to such diversities. Recently surged learning-based CCAs have great potential in adaptability and flexibility but are not … WebDec 1, 2016 · Loss-based congestion control operates at the right edge of the bandwidth-limited region, delivering full bottleneck bandwidth at the cost of high delay and frequent packet loss. When memory was expensive buffer sizes were only slightly larger than the BDP, which minimized loss-based congestion control's excess delay.

WebThe congestion control strategy plays an essential role in the high-speed datacenter network. It aims to deliver low latency, high throughput network service. RTT-based … WebFeb 2, 2024 · BBR uses a different approach to control congestion, the one that is not based on packet loss. BBR measures the network delivery rate and RTT after each ACK, building an explicit network model that includes the maximum bandwidth and the minimum RTT. Based on the model, BBR knows how fast to send data and the amount of data it can send over a …

WebRTT variances as a congestion indicator. These delay-based approaches are more-or-less derived from seminal work of TCP Vegas [7]. One core idea of delay-based congestion avoidance is that the increase of RTT is considered as early indicator of congestion, and the sending rate is reduced to avoid self-induced buffer overflow.
