Alcatel-Lucent 5750 Subscriber Services Controller 11
Dynamic Bandwidth Management
and Usage Accounting
The Alcatel-Lucent 5750 SSC allows service providers to differentiate and
evolve from basic HSI-access commodity services. With traditional flat-rate,
“all-you-can-eat” Internet services, subscribers often think they are paying too
much for a service without the guarantee that sufficient bandwidth is provided
when needed. The Alcatel-Lucent 5750 SSC combats this issue by enabling
dynamic, mid-session policy modifications based on subscriber- or application-
initiated bandwidth requests, usage metering, and accounting functions. The
system’s design enables the introduction and enforcement of specific volume,
bandwidth and usage quotas (e.g., for peer-to-peer Internet applications, to
create differentiated service subscriptions and apply application-usage quotas).
Volume-metering functions keep track of consumed resources on a per-subscriber
and per-service basis and can dynamically trigger session QoS or bandwidth
policy changes when thresholds are crossed. Alternatively, users can be redirected
to a subscriber portal to buy more bandwidth capacity or upgrade a service.
As a result, end users have more control over their service experience, with
the option to pay per usage rather than lock themselves into a fixed band width
tier that may not meet their budget or application requirements.
