The data of multiple Ethernet users received from the same station is transmitted on the same
VCTRUNK and isolated by using different VLAN IDs. In this way, the bandwidth is shared on
the SDH side.
Service Requirement
In the network as shown in
, the service requirements are as follows:
l
Two branches of user D are located at NE1 and NE2, and need to communicate with each
other.
l
Two branches of user E are located at NE1 and NE2, and need to communicate with each
other.
l
The services of user D need to be isolated from the services of user E. The traffic of user
D and user E, however, are complementary in terms of time and can share a 20 Mbit/s
bandwidth.
l
The Ethernet equipment of user D and user E provides 100 Mbit/s Ethernet ports of which
the working mode is auto-negotiation, and does not support VLAN tags.

Board Configuration Information
The Ethernet switching boards that support EVPL services are provided in
In this example, NE1 and NE2 each are configured with an EFS8 board. Different VLAN IDs
are used to isolate the data of different users transmitted on the same VCTRUNK.
l
When the data of user D arrives at the transmission network, the VLAN ID of 100 is added
to the data. When the data leaves the transmission network, the VLAN tag is stripped.
l
When the data of user E arrives at the transmission network, the VLAN ID of 200 is added
to the data. When the data leaves the transmission network, the VLAN tag is stripped.
