11.2.2 Principle of QoS Data Plan
The QoS plan for FTTB is an E2E planning, and it can be divided into following policies: traffic
classification, marking, scheduling, traffic monitoring, and DBA policies.

Note
l Different service packets are distinguished by different VLAN IDs. GEM ports are mapped
based on 802.1p priorities for the GPON system.
l Service priorities in this table are recommended values. The service priorities are arranged
according to the operators's actual planning.

DBA type Type 3 (DBA profile: assured bandwidth + maximum bandwidth. Users
are allowed to preempt the bandwidth on condition that the users' assured
bandwidth is guaranteed. However, the total bandwidth cannot exceed the
maximum bandwidth.)
DBA bandwidth
planning
Configure the DBA bandwidth according to the user's bandwidth package.
The assured bandwidth is the maximum bandwidth required by
management packets, VoIP, and IPTV upstream packets. The maximum
bandwidth is larger than or equal to the maximum bandwidth that users
apply.
