Introduction
Service Pipes
Service Pipe is a virtual connection between a Subscriber's application
and the Network Resource. The Network Resource might be Internet,
Content Provider, Corporate Network, etc.
The Service Pipes are implemented as IEEE 802.16 connections within
the wireless domain. Each Service Pipe can include up to 4 uplink and
4 downlink connections. Implementation within the provider's backbone
domain depends on the specific backbone network.
A Subscriber is an entity that may be associated with any number of
devices connected to any number of SUs. Each Service Pipe associates a
certain Service Profile with Subscriber's device(s) behind a specific SU.
The Service Profile's properties depend on the Service Type. All data
Service Pipes have the following properties:
VLAN ID based Classification: Each Service Pipe can be associated
with up to 16 VLAN IDs, enabling creation of VLANs within the
wireless domain and differentiation of services to different end-users
behind the same SU based on VLAN ID classification.
NOTE
In the current version, the proper use of VLAN ID based classification for differentiating
among several end-users that are served by the same SU is possible only with a VLAN
switch with VLAN Binding capability.
Quality of Service and Policy (Priority based) Classification: Up to 4
uplink and 4 downlink QoS profiles can be assigned to each Service
Pipe. The data will be mapped onto these connections by either
IEEE 802.1p or DSCP priority tags. This will lead to creation of the
corresponding number of Uplink and Downlink connections
supporting differentiated services to up to 4 applications based on
either IEEE 802.1p or DSCP prioritization schemes. In cases where
prioritization is not used, a single pair of uplink/downlink
connections is created.
