23 MANAGING BANDWIDTH AND
AUTHENTICATION
This section provides a high-level description of BAM in a Canopy network. For more
specific information, see Canopy Bandwidth and Authentication Manager (BAM) User
Guide.
23.1 MANAGING BANDWIDTH WITHOUT BAM
Unless BAM is deployed and is configured in the AP, bandwidth management is limited to
applying a single sustained data rate value (for uplink and for downlink) and a single
burst allocation value (for uplink and for downlink) to every SM that registers in the AP.
23.2 BANDWIDTH AND AUTHENTICATION MANAGER (BAM)
SERVICES AND FEATURES
BAM enables you to perform the following management operations on SMs:
◦ Change the key that the SM(s) need for authenticating.
◦ Temporarily suspend or reinstate a subscriber.
◦ Set burst size and data transfer rate caps for an SM or group of SMs.
◦ Use licensing to uncap an SM or group of SMs.
◦ List all ESNs that are associated with a specified VLAN ID.
◦ Associate or dissociate an SM or group of SMs with a specified VLAN ID.
◦ Set VLAN parameters.
◦ Toggle whether to send those VLAN parameters to the SM(s).
◦ Set CIR parameters for low-priority and high-priority channel rates.
◦ Toggle whether to send those CIR parameters to the SM(s).
◦ Toggle whether to enable the high-priority channel in the SM(s).
23.2.1 Bandwidth Manager Capability
Canopy Bandwidth and Authentication Manager (BAM) software allows you to set per-SM
bandwidth for a sustained rate and for a burst rate. With this capability, the Canopy
system allows both
◦ burst rates beyond those of many other broadband access solutions.
◦ control of average bandwidth allocation to prevent excessive bandwidth usage by
a subscriber.
All packet throttling occurs in the SMs and APs based on Quality of Service (QoS) data
that the BAM server provides. No BAM server processing power or network messages
are needed for packet throttling.
QoS management also supports marketing of broadband connections at various data
rates, for operator-defined groups of subscribers, and at various price points. This allows
you to meet customer needs at a price that the customer deems reasonable and
affordable.
