Chapter 4 - Operation and Administration
Forwarding Rules: A Forwarding Rule is assigned to each Service
Pipe, defining various features that define the handling of certain
message types in the wireless domain. These may include Unicast
and Multicast Forwarding rules, QoS Profile and VLAN ID 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 IEEE 802.1d
Bridge.
Aggregation: Several Service Pipes in the Wireless Domain may be
aggregated into a single Virtual Private Link (VPL) in the backbone
domain.
Auto-configuration: The Ethernet Addresses of the Subscribers' PCs
are automatically learnt just as in a standard IEEE 802.1d Bridge.
For each Ethernet Address it also learns the VLAN behind the SU it
belongs to.
Currently, the following Service Pipe types are supported:
L2 (layer 2) Data Service
PPPoE Data Service
Service Types
L2 Service
L2 (Layer 2) service transports Layer 2 (Ethernet) frames between
subscriber's site and the Network Resource located behind the
provider's backbone and/or between 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 might be different from IP. The Network Resource is
assumed to be a corporate network.
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 Access Concentrator behind the Base Station. The
frames are forwarded only between the Subscribers' PCs and the PPPoE
Access Concentrator. Frames that are not PPPoE Ethertype are
discarded. In the uplink frames are never relayed but only forwarded to
the Access Concentrator. In the downlink, broadcasts are allowed only
in cases of unknown addresses.
