Data center bridging (DCB) Ethernet enhancements are available to improve Ethernet networking and management in data center environments. DCB is a framework that defines the enhancements that are required for switches and endpoints. DCB includes the following features:
PG, also known as ETS, which is a priority grouping specification that provides bandwidth management as well as a scheduling algorithm for various traffic classes on a converged link.
PFC, which is an enhancement to the existing Ethernet-pause protocol, that enables 0-drop packet delivery for certain traffic classes.
This release of the SEFOS DCB feature supports DCB version 1.0.1 and IEEE DCBX as specified by the DCB task group.
