9500 Mpr Rel. 3.1 - Alcatel-Lucent 9500 MPR User Manual

Queues 1 to 4 are assigned to Ethernet traffic according to the information inside the packet as 802.1p
field, DiffServ field, Ethertype or 802.1Q VLAN_ID.
TDM flows classification
All the TDM2TDM traffic flows are assigned to the highest egress priority queue (Q8). All the TDM2ETH
traffic flows are assigned to the Q7 egress priority queue. All the MEF-8 ETH2ETH traffic flows are
assigned to the Q5 egress priority queue.
TMN flows classification
All TMN traffic flows are assigned to the Q6 egress priority queue.
QoS based on IEEE std. 802.1p
When 802.1p QoS mechanism is adopted, the reference is the standard "IEEE 802.1D-2004 Annex G
User priorities and traffic classes" that defines 7 traffic types and the corresponding user priority values.
Considering that in the Radio Interface module for generic Ethernet traffic there are five egress queues
the mapping 802.1p value to queue is the following:
