Configuring VCTRUNK-Shared EVPL (VLAN) Services

Configuring VCTRUNK-Shared EVPL (VLAN) Services

When the data of multiple users without VLAN tags sent to a transmission network is transmitted on the same VCTRUNK, the VCTRUNK-shared EVPL (VLAN) service is used to isolate the data by adding VLAN tags. In this way, the bandwidth is shared on the SDH side.

Networking Diagram

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 Figure 2-73, the service requirements are as follows:

  • Two branches of user D are located at NE1 and NE2, and need to communicate with each other.
  • Two branches of user E are located at NE1 and NE2, and need to communicate with each other.
  • 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.
  • 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.
Figure 2-73  Networking diagram for configuring VCTRUNK-shared EVPL (VLAN) services

NOTE:

This topic considers the OptiX OSN 550 as an example to describe the board layout. In the case of other products, the configuration method is the same, except for the slots. For the slot information, see the Hardware Description of the relevant product.

Board Configuration Information
The Ethernet switching boards that support EVPL services are provided in Table 2-152.

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.

  • 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.
  • 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.

Signal Flow and Timeslot Allocation

The services of multiple users that are received from different external ports on an Ethernet board are tagged with different VLAN IDs and then transmitted on the same VCTRUNK. In this way, the data of different users is isolated. After the data arrives at the sink node, the VLAN tags are stripped.

Figure 2-74 shows the signal flow of the VCTRUNK-shared EVPL (VLAN) services and the timeslot allocation to the VCTRUNK-shared EVPL (VLAN) services.

For the method of calculating the bandwidth of the Ethernet services carried by a VCTRUNK, see Ethernet Service Bandwidths Carried by VCTRUNKs of Ethernet Boards.

Figure 2-74  Signal flow and timeslot allocation

  • The EVPL services of user D and user E that share VCTRUNK1 occupy the first to tenth VC-12 timeslots of the first VC-4 (VC4-1:VC12:1-10) on the SDH link from NE1 to NE2.
  • The services are added and dropped by using the first to tenth VC-12 timeslots of the fourth VC-4 (VC4-1:VC12:1-10) on the EFS8 board of NE1 and the first to tenth VC-12 timeslots of the fourth VC-4 (VC4-1:VC12:1-10) on the EFS8 board of NE2.

Configuration Process (Configuration on a Per-NE Basis)

Ethernet switching boards are required on both the source and sink nodes for creating EVPL services of different VLAN IDs. In this way, the packets received from different external ports are added with different VLAN tags. As a result, the packets are isolated when they are transmitted on the same VCTRUNK.
