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).
