Functional description

MPR-e and MSS-1c User Manual 3DB19901EFAA Edition 01 169

For each egress port according to method of QoS classification configured in the switch,

the packets are assigned to each queue.

3.10.13.1.1 — TDM flows classification

All the TDM traffic flows will be assigned to the highest egress priority queue (Q4).

3.10.13.1.2 — Ethernet flows classification

For generic Ethernet flows in the switch the priority of each packet can be assigned

according to the information in:

• IEEE 802.1p: the packet is examined for the presence of a valid 802.1P user-priority

tag. If the tag is present the correspondent priority is assigned to the packet

• DiffServ: each packet is classified based on DSCP field in the IP header to determine

the priority.

3.10.13.1.3 — Scheduler

The scheduler algorithm cannot be configured. HQP scheduler algorithm is used on queue

Q4.
