Watch Meta’s engineers discuss QUIC and TCP innovations for our network

This post details several innovations in QUIC and TCP for Meta's network. It introduces Quick cache DSR for bypassing intracluster communication in CDNs, QUIC Jump Start for reducing backbone network transfer startup delays, DCTCP for sustained data center congestion, receiver window tuning for data center bursts, NetEdit for fine-grained network tuning at scale using BPF, and a network entitlement framework for WAN resource sharing. These contributions focus on improving efficiency, reliability, and performance across various network layers.
