Note that not all the solutions support all modes.
The most basic mode is Subscriber-less mode. In this mode, there is no notion of subscriber in
the system, and the entire link where the SCE Platform is deployed is treated as a single
subscriber. Global Application level analysis (such as total p2p, browsing) can be conducted, as
well as global control (such as limiting total p2p to a specified percentage). From a configuration
stand point, this is a turnkey system and there is no need to integrate or configure the system from
a subscriber perspective.
In Anonymous subscriber mode, analysis is performed on an incoming subscriber-IP address, as
the SCE Platform creates an 'anonymous/on-the-fly' record for each subscriber. This permits
analyzing traffic at an individual IP address level (for example, to identify/monitor what a
particular 'subscriber' IP is currently doing) as well as control at this level (for example, to limit
each subscriber's bandwidth to a specified amount, or block, or redirect). Anonymous-subscriber
allows quick visibility into application and protocol usage without OSS integration, and permits
the application of a uniform control scheme using predefined templates.
There are two possible Subscriber Aware modes. In these modes, subscriber IDs and currently
used IP addresses are provisioned into the SCE Platform. The SCE Platform can then bind usage
to a particular subscriber, and enforce per-subscriber policies on the traffic. Named reports are
supported (such as top subscribers with the OSS IDs), quota-tracking (such as tracking a
subscriber-quota over time even when IP addresses change) as well as dynamic binding of
packages to subscribers. The two Subscriber Aware modes are:
• Static subscriber aware: The IP addresses are static. The system supports the definition of
static-subscribers directly to the SCE Platform. This is achieved by using the SCE Platform
CLI, and defining the list of subscribers, their IP addresses and policy information using
interactive configuration or import/export operations.
• Dynamic subscriber aware: The IP addresses change dynamically for each subscriber login
into the Service Provider’s network. In this case, subscriber awareness is achieved by
integrating with AAA and provisioning systems for dynamically obtaining network-ID to
subscriber ID mappings, and distributing them to the SCE Platforms.
Aging Subscribers
Subscribers can be aged automatically by the SCE 1000. ‘Aging’ is the automatic removal of a
subscriber, performed when no traffic sessions assigned to it have been detected for a certain
amount of time. The most common usage for aging is for anonymous subscribers, since this is the
easiest way to ensure that anonymous subscribers that have logged-out of the network are
removed from the SCE 1000 and are no longer occupying resources. Aging time can be
configured individually for introduced subscribers and for anonymous subscribers.
