Feature Descriptions
MDM9000 Satellite Modem
16.17.2 Access VLAN Mechanism between Hub and Remote Sites
In this example there are three VLAN's. All data traffic from VLAN 1 must be forwarded to remote 1
and all data traffic for VLAN 2 must be forwarded to remote 2.
Please refer to the following picture:
The following steps are performed in the encapsulator.
1. Data traffic is inserted into the MDM9000.
2. The classification rule is applied to filter on, for example IP destination address, the IP protocol
used or an other classification expression.
3. The classified traffic is put into a shaping node (Node1 and Node2), where the CIR and PIR is
performed.
4. The shaped traffic is inserted into a channel.
Note: Create a channel per VLAN to keep this traffic separated.
Add the Access VLAN tag to filter the VLAN and making the channel a member of that VLAN.
(This is a filter on top of the classification rule).
Note, the VLAN tag is stripped from the IP packet, reducing overhead on the satellite link.
5. The channel (and its content) is encapsulated and an ISI (input stream identifier) is applied.
There are two channels inserted into the ISI.
