6.1. Simple scheduling mode

In simple scheduling mode, for incoming packets, according to the conversion of the outer
VLAN
cos value (VLAN is the single VLAN cos, VLAN SVLAN double cos value) the uplink port
will determine the packet Local Priority (internal use priority with 0-0 mapping by default,
the ACL rule can be used to modify the message Local Priority);

At the entrance of uplink port, configure the mapping relationship between internal
priorities
and PON out-going queue, and configure the sheduling policy at the export of
PON (including: SP strict priority scheduling strategy, WRR weighted round robin
scheduling strategy, and SP+WRR hybrid scheduling
strategy)

At PON port, it's optional to configure the maximum/minimum bandwidth for each
queue, and the limiting rate.
6.2. Hierarchical scheduling
There are three levels of scheduling:

The first level is scheduling between each ONU (this level scheduling mode can be changed,
the default is SP);

The second level is scheduling between each ONU under each PON port (this level of
scheduling is fixed to WRR, the default weight can be changed with is 1 by default);

The third layer scheduling is between ONU and the multicast channel (this level can not
be changed, fixed as SP, and the multicast channel has higher priority).
