• cutoff
O
optical splitter topology
In this topology, the SCE 1000 does not
reside physically on the data link. Data is
forwarded to the SCE 1000 via an optical
splitter, which splits the traffic on the link,
sending all information to the SCE 1000 in
parallel with its transmission through the
optical splitter. The optical splitter is
connected physically on the Gigabit Ethernet
link and only the receive inputs of the data
link GBE interfaces in the SCE 1000 are
connected to the optical splitter.
P
PQI (Service Control Application
Installation) File
An application package file that is installed
on the SCE Platform and the Collection
Manager.
R
RDR (Raw Data Record)
A data record produced by the SCE Platform
that reports on events in the traffic. RDRs
produced by the SCE Platform are sent to
the Collection Manager and then stored in
the Collection Manager database or
forwarded to third-party systems. The RDR
typically contains quota (see Quota) request
or reports service usage.
RDR Formatter
An internal component of the SCE Platform
that gathers the Raw Data Records (RDRs),
formats them, and sends them to an external
data collector.
Receive-only connection mode
The SCE Platform does not reside physically
on the data link, and therefore can only
receive data and does not transmit.
S
SCE Platform
The SCE Platform is a purpose-built service
component and active enforcing system
designed for enhancing service providers
and backbone carrier networks. By
identifying, classifying, and manipulating
complex traffic flows at wire-speed, the SCE
Platform transforms simple transport
networks into differentiated service delivery
infrastructures for a wide variety of value-
added IP applications, such as video
streaming, VoIP, tiered services, and bilateral
application-level SLAs.
The SCE Platform seamlessly interfaces
with existing network elements—including
routers, switches, aggregators, subscriber
management devices, and operational
support systems—using industry standard
interfaces and communications protocols.
The need to guarantee that packets passing
through the network are processed at the rate
they arrive makes it necessary to provide a
custom-made hardware solution.
The SCE Platform comes in three models:
SCE 1000 2xGBE, SCE 2000 4xGBE and
SCE 2000 4/8xFE. There may be one or
more SCE Platform on the provider network.
Within the SCE Platforms, network
transactions are analyzed and mapped to
services that enforce the provider’s policies.
In addition, the SCE Platform implements
the business logic of the system solution and
performs the transaction analysis in real
time. When so instructed, the SCE Platform
creates a Raw Data Record (RDR) to be sent
for storage to the system’s data repository,
the Collection Manager (CM); or carries out
some other operation such as bandwidth and
volume control.
