When bottleneck buffers are large, loss-based congestion control keeps them full, causing bufferbloat, causing low throughput, and when bottleneck buffers are small, loss-based congestion control misinterprets loss as a signal of congestion, leading to low throughput.
Abstract
When bottleneck buffers are large, loss-based congestion control keeps them full, causing bufferbloat. When bottleneck buffers are small, loss-based congestion control misinterprets loss as a signal of congestion, leading to low throughput. Fixing these problems requires an alternative to loss-based congestion control. Finding this alternative requires an understanding of where and how network congestion originates.
