Step 6.
The
priority-queue
parameter allows allocation of all services of one T-CONT into queues with
priorities (if ONT supports this method).
20.2.2.
DBA Profile Configurationn
This profile configures dynamic bandwidth allocation (DBA). These parameters allow specification of any
T-CONT type described in G.984.3.
Step 1.
First of all, choose a
service-class
, which will define the basic DBA algorithm.
Step 2.
After that configure
status-reporting
which defines a type of ONT queues status report.
Step 3.
The
fixed-bandwidth
,
guaranteed-bandwidth
, and
besteffort-bandwidth
parameters define the
fixed, guaranteed, and best-effort bandwidth correspondingly.
DBA configuration is described in details in Chapter 21, page 88.
20.2.3.
Shaper Profile Configuration
Configuration of this profile allows restriction of upstream and downstream services.
Step 1.
Downstream restriction in OLT uses the policing algorithm. The restriction can either use one
policer for all services or individual policers for each separate service. This is specified in the
one-policer
parameter. When one policer is used for all services, only
policer 0
should be specified; otherwise
policers for all services should be adjusted.
Step 2.
Upstream restriction in ONT uses the shaping algorithm. You can specify either a global shaper
or individual shapers for unicast, multicast, and broadcast traffic (ONT functionality).
20.2.4.
Ports Profile Configuration
The "ports" profile allows you to group ports in ONT. The profile also contains IGMP and multicast
setting as they are separately adjusted for each port.
You can adjust up to 4 Ethernet ports and a VEIP virtual port which will serve as a link between OMCI
and RG domains in ONT.
Step 1.
Ethernet ports are grouped with the help of the
bridge-group
parameter. Value 0 means that
the port is associated with an RG domain (router). Other values means port association with an OMCI
domain, i. e. the port can be directly used in OLT to establish a data communication channel.
Step 2.
IGMP and multicast configuration is described in details in Chapter 24, page 105.
