draft-briscoe-iccrg-prague-congestion-control-04 - IETF Datatracker
The is a scalable congestion control mechanism designed for the L4S (Low Latency, Low Loss, and Scalable Throughput) architecture. Prague
: Requires a more granular feedback mechanism than standard TCP to react to the extent of congestion rather than just its existence . Prague
: Sources must set the ECT(1) codepoint in the IP header to identify as L4S-capable. Prague
: Implements a "virtual RTT" to prevent flows with very low Round-Trip Times from dominating others.
