9.6.3 Principle of Internet Access Service Data Plan

The Internet access service plan mainly includes the plan of the VLAN and VLAN translation
policy in different network scenarios.

The rate restriction on the BRAS or SR is recommended. OLTs and ONTs do not restrict
the rate for service streams.
If BRAS does not support rate restriction, OLTs can restrict the rate for service streams
through the traffic profile.
Different service packets on the ONT are distinguished by different VLAN IDs. The service
packets are mapped to GEM ports based on VLAN IDs so that different service packets
are transmitted to different GEM ports. Each GEM port (each service) corresponds to a T-
CONT or all GEM ports share a T-CONT.
The sum of the assured bandwidth of all ONTs connected to a PON port and the fixed
bandwidth of OMCI management channel is less than the GPON upstream bandwidth.
Some bandwidth must be reserved for the future service expansion.

Bandwidth Description
VLAN Translation Policy
ONT: ONTs configure the VLAN and
add the same C-VLAN tag to packets. All
ONTs are in the same C-VLAN.
OLT: The OLT performs VLAN
translation: C<->S+C'. The C'-VLAN of
every ONT differs from each other.
