P802.1Qdt – Priority-based Flow Control Enhancements

This amendment specifies procedures and managed objects for automated Priority-based Flow Control (PFC) headroom calculation and Media Access Control Security (MACsec) protection of PFC frames, using point-to-point roundtrip measurement and enhancements to the Data Center Bridging Capability Exchange protocol (DCBX). This amendment places emphasis on the requirements for low latency and lossless transmission in large-scale… read more »

P802.1Qcz – Congestion Isolation

This amendment specifies protocols, procedures and managed objects that support the isolation of congested data flows within data center environments. This is achieved by enabling systems to individually identify flows creating congestion, adjust transmission selection for frames of those flows, and signal to neighbors. This mechanism reduces head-of-line blocking for uncongested flows sharing a traffic… read more »
