The prioritization of an Ethernet data flow can be indicated on the three user-priority bits
(802.1p) of the "Tagged-Ethernet" frame and also on the 3 "provider-priority" bits of the
"Stacked-Vlan" frame.
Eight levels of User-priority can be defined: pri0 ... to pri7, where pri0 is the minimum
and pri7 the maximum. The relayed traffic towards a generic "Provider Network" can be
"prioritized" using the "Default" or "Regenerated" UserPriority" settings.
Sixty four levels of DSCP can be defined: DSCP0...to DSCP63, where DSCP0 is the
minimum and DSCP63 is the maximum.
The policing is a mechanism to check that the data flow is respecting the traffic contract,
providing to "cut" or to forward the incoming traffic.
"Disabled" means that no policing is carried out
•
"Color-Blind" means that the policing is based upon the Traffic Descriptor (TD),
•
without taking into account the Priority and CoS
"Color-Aware" (not yet operative), means that the policing takes into account the
•
Traffic Descriptor (TD), the UserPriority and the CoS, by means of a defined "Color
Profile" (not yet operative)
According to the traffic contract, to the policing mode, and to the available bandwidth, the
priority of a data flow into the Provider-network is assigned by the traffic scheduler of the
system.
In case that the policing is in "Color-aware" mode, the Provider-prioritization granularity
is made deeper, taking into account the single VLAN-priorities, that can have assigned to
any of them a green or yellow or red color.
