EDA 1200 Services

6. Traffic mapping between one End-user VLAN and one Service VLAN. This

traffic mapping applies to VDSL2 and Fiber/Cat5.

7. Traffic mapping between an IP destination address in the upstream and a

Service VLAN. This traffic mapping only applies in Fiber/Cat5.

A Service VLAN can also be used to create layer-2 connections to other

End-users, either locally through the aggregation network or across a transport

network, creating a Transparent LAN Service (TLS), see EDA 1200 DSL Line

Features description.

The services may have different QoS demands. The Ethernet in the aggregation

network is capable of treating frames with different QoS classification differently.

The EDA 1200 Service allows for different traffic

Flows with different QoS

through the same PVC, or over the same VLAN, thus ensuring differential

treatment of traffic through the DSL connection.

3.1.2.1 Multicast in Separate VLANs

Regardless of other traffic mapping schemes and mode (PTM or ATM), it is

possible to create separate VLANs through which all the multicast traffic to and

from the End-users is sent. If a VLAN ID and priority are defined in the Multicast

Whitelist, all multicast traffic from a specific multicast range will flow through a

dedicated VLAN in the network and with the specified priority. The priority is

the priority of multicast traffic (including IGMP messages) sent upstream. The

downstream traffic priority is set by the multicast router.

Figure 19 VLAN Separated Traffic Based on Multicast Whitelist

If a VLAN is not specified for a multicast range (unspecified) the multicast

traffic will be sent in the VLAN specified for the service, together with all other

unicast traffic.

For more information about Whitelists please refer to EDA 1200 DSL Line
