Priority-based flow control
Encyclopedia
Priority-based flow control, as defined in computer networking by the standard IEEE 802.1Qbb, provides a link-level flow control
mechanism that can be controlled independently for each Class of Service
(CoS), as defined by IEEE P802.1p. The goal of this mechanism is to ensure zero loss under congestion in data center bridging
(DCB) networks.
Ethernet flow control
Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks.-Description:Ethernet is a popular family of computer network protocols. Flow control can be implemented at the data link layer...

Class of service
-Class of service :As related to network technology, CoS is a 3-bit field within an Ethernet frame header when using 802.1Q tagging. The field specifies a priority value of between 0 and 7 inclusive that can be used by quality of service disciplines to differentiate traffic.While CoS operates only...

Data center bridging
Data center bridging refers to a set of enhancements to Ethernet local area networks for use in data center environments. Specifically, DCB goals are, for selected traffic, to eliminate loss due to queue overflow and to be able to allocate bandwidth on links. Essentially, DCB enables, to some...
