Apple Inc. In the past decade there has been growing awareness about the harmful effects of bufferbloat in the network, and there has been good work on developments like L4S to address that problem. However, bufferbloat on the sender itself remains a significant additional problem, which has not received similar attention.

These improvements are broadly applicable across all datagram and transport protocols (UDP, TCP, QUIC, etc.) on all operating systems.
