Ericsson MINI-LINK 6351 Technical Description page 27

MINI-LINK 6351 supports priority handling according to IEEE802.1Q 2005 and
IEEE802.1D 2004. In a network, it is important to only use one set of priority
definitions (for example, IEEE 802.1D 2004). Otherwise, the handling of traffic
types can differ between parts of the network in a non-predictable way.
4.4.1 Classification
The classification mechanism extracts customer priority in frames that enter
the operator domain.
The classification mechanism can extract the following types of customer
priority:
•
•
•
•
The classification mechanism also supports the following types of combined
customer priority extraction:
•
•
4.4.2 Marking
The marking mechanism sets the operator priority.
If a frame contains trusted customer priority, the marking mechanism can use
the customer priority together with a mapping table to set the operator priority.
The marking mechanism sets the operator priority to the default priority in the
following cases:
•
•
4.4.3 Policing
The policing mechanism makes sure that a customer does not use more than
the allowed resources in a network.
The policing mechanism limits the input bit rates based on a bandwidth profile.
The bandwidth profiles support the MEF concepts Committed Information
