12.2.3 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 sum of the assured bandwidth of all ONUs 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.
VLAN Plan
Double-tagged VLAN
Double-tagged VLAN
UserVLAN: VLAN carried by upstream packets of user-side devices, U for short.
C-VLAN: VLAN added based on the ONU port. For details, see the description of the
Double-tagged VLAN S+C.
Double-tagged VLAN S+C: C indicates the inner VLAN (C-VLAN) and S indicates the
outer VLAN (S-VLAN).
Double-layer VLAN S+C': C' indicates the translated inner VLAN (C'-VLAN) and S
indicates the outer VLAN (SVLAN).
Single-tagged S-VLAN: Single-tagged VLAN marked or translated by the OLT. It is
generally used in a single-tagged VLAN translation scenario.
C<->S+C': Bidirectional VLAN translation: translates the inner C-VLAN and then adds
one outer S-VLAN.
C<->S+C: Bidirectional VLAN translation: maintains the inner C-VLAN and adds one
outer S-VLAN.

VLAN Translation Policy
ONU: The upstream packets sent from
the Router carry user-VLANs and the
ONU transparently transmits them.
OLT: The OLT translates the U-VLAN
to S-VLAN+C-VLAN.
ONU: ONUs configure the VLAN and
add the same C-VLAN tag to packets. All
ONUs are in the same C-VLAN.
OLT: The OLT performs VLAN
translation: C<->S+C'. The C'-VLAN of
every ONU differs from each other.
