5.8 Quality of Service (QoS)

5.8.1 Priority Flow Control and Link Level Flow Control

Priority Flow Control (PFC) provides an enhancement to the existing pause mechanism in Ether-

net. The current Ethernet pause option stops all traffic on a link. PFC creates eight separate vir-

tual links on the physical link and allows any of these links to be paused and restarted

independently, enabling the network to create a no-drop class of service for an individual virtual

link. PFC has 8 possible priorities (3 bits in VLAN header). Each priority can be mapped to one

of 4 possible queues in the ingress.

The PFC software offers the following features:

• Provides per-priority enabling or disabling of flow control
