9500 MPR Rel. 3.1
3DB18809AAAA Issue 1 197/980
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:
QoS based on DiffServ
802.1p priority Queue
111, 110 Q5 (higher priority)
101 Q4
100 Q3
011, 000 Q2
010, 001 Q1
DiffServ priority Queue
111000, 110000, 101110, 101000 Q5 (higher priority)
100110, 100100, 100010, 100000 Q4
011110, 011100, 011010, 011000 Q3
010110, 010100, 010010, 010000
