Managing Subscribers
Subscriber Modes in Service Control Solutions
Service Control solutions support several modes of handling subscribers:
•
•
•
•
Note that not all the Service Control 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 network ID (IP address, VLAN
or VPN ID), as the SCE platform creates an 'anonymous/on-the-fly' record for each subscriber. This
permits analyzing traffic at an individual network ID 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
network IDs 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
network IDs change) as well as dynamic binding of packages to subscribers. The two Subscriber Aware
modes are:

OL-7827-12
Subscriber-less mode
Anonymous subscriber mode
Static subscriber aware mode
Dynamic subscriber aware mode
Static subscriber aware — The network IDs 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 network IDs and policy information using interactive
configuration or import/export operations.
Dynamic subscriber aware — The network IDs change dynamically for each subscriber login into
the Service Provider's network. In this case, subscriber awareness is achieved by integrating with
external provisioning systems (either directly or through the SM) to dynamically learn network-ID
to subscriber mappings, and distribute them to the SCE platforms.
MPLS/VPN-based subscribers are supported only in the dynamic subscriber aware mode. The
system must dynamically map the internal MPLS label and the MAC address of the PE to the correct
VPN subscriber.
