11.1. Overview
The ASWipLL system allows operators and service providers to manage the
bandwidth policy allocated to their subscribers, assuring optimal network
performance. The bandwidth policy is per BSR, and thus, applies to all SPRs
associated with the BSR.
ASWipLL allows operators to define a maximum bandwidth for each subscriber,
referred as
maximum information rate (MIR). In addition, ASWipLL allows
operators to provide a guaranteed bandwidth, referred as committed information rate
( CIR), to a subscriber even when the network is loaded. Typically, subscribers pay
different rates for the levels of desired bandwidth commitment. Different levels of
CIR and MIR can be sold as different services (e.g. Platinum, Gold, Silver, and
Bronze) at different prices.
ASWipLL allows the operator to implement the following bandwidth policies:
Asymmetric CIR/MIR: different downlink and uplink values for CIR and MIR.
In other words, you need to define CIR and MIR values for downlink, as well as
define CIR and MIR values for uplink.
Downlink refers to traffic from Base
Station to subscriber; uplink refers to traffic from subscriber to Base Station.
This is useful in applications such as cable TV (CATV), where a higher
downlink bandwidth is needed than in uplink.
Aggregated CIR/MIR : CIR and MIR values defined for the sum of the
downlink and uplink traffic. In other words, you need to define one CIR value
that applies to both downlink and uplink, and define one MIR value that applies
to both downlink and uplink. This is useful when there exists varying bandwidth
demands on the network, different applications, or different user types. For
example:
MIR (downlink and uplink): 1500 bps
CIR (downlink and uplink): 256 bps
No bandwidth policy: subscriber receives MIR, but if the network is unable to
maintain this bandwidth, the subscriber receives less. This is an unpredictable
bandwidth policy, whereby the subscriber may receive no bandwidth at all. In
addition, no proportional degradation is implemented in this policy.
