wireless domain. These may include Unicast and Multicast Forwarding rules,
QoS Profile for Multicasts and Unknown Address Forwarding Policy. The
available features depend on the Service Type. The data may be switched only
between the Services that share the same Forwarding Rule. In all other
respects the service functions as a standard Bridge.
Aggregation: Several Services in the Wireless Domain may be aggregated into a
single Virtual Private Link (VPL) in the backbone domain.
Priority Marking: Ethernet frames transmitted to the backbone may be marked
with a configurable priority (DSCP or IEEE 802.1p), enabling the upstream
network to handle the traffic accordingly.
Auto-configuration: The Ethernet Addresses of the Subscribers' PCs are
automatically learnt just as in a standard Bridge. For each Ethernet Address it
also learns the VLAN behind the SU it belongs to.
Currently, the following Service types are supported:
L2 (layer 2) Data Service
PPPoE Data Service
Voice Service
4.10.1.2 Service Types
4.10.1.2.1 L2 Service
L2 (Layer 2) service transports Layer 2 (Ethernet) frames between the subscriber's
site and the Network Resource located behind the provider's backbone and/or
between the subscriber's sites. It is assumed that the backbone either supports
encapsulation of the Layer 2 frames (e.g. over ATM) or routes the frames according
to the applicable Layer 3 protocol, which could be different from IP. The Network
Resource is assumed to be a corporate network.
4.10.1.2.2 PPPoE Service
PPPoE (Point-to-Point Protocol over Ethernet) Access service provides connectivity
between a PPPoE enabled devices at the subscriber's site and a PPPoE aware
NOTE
An L2 Service supports also DRAP-based Voice Service, as described in the next page.
