P802.1Qdw – Source Flow Control

his amendment specifies procedures, managed objects, and a YANG data model for the signaling and remote invocation of flow control at the source of transmission in a data center network. This amendment specifies enhancements to the Data Center Bridging Capability (DCBX) protocol to advertise the new capability. This amendment specifies the optional use of existing stream filters to allow bridges at the edge of the network to intercept and convert signaling messages to existing Priority-based Flow Control (PFC) frames. This amendment also addresses errors and omissions in the description of existing IEEE Std 802.1Q functionality.
