ICSP™ Service Proxy
[ specifications  ]
An integral part of the Distributed Softswitch Architecture, the ICSP™ service
proxy provides the service intelligence required to route calls and deliver a variety of
next-generation and traditional services to residential and enterprise customers.
The Distributed Softswitch Architecture
The Distributed Softswitch Architecture is an open, standards-based platform that is
uniquely designed to enable advanced services — not
just a decoupling of a legacy circuit switch. Designed with a forward-looking approach to
voice networks, the architecture distributes call processing across multiple network elements
rather than tying
it to one central platform.
The architecture consists of the ICS2000™ media gateway,
the ICSP™ tandem service proxy, the ICSG™ signaling gateway
and the ICView™ management system. The ICSG consolidates and
preserves A-links supporting a network of ICS2000 media gateways
and ICSP service proxies. Network routing and service intelligence
is distributed on the ICSP platform, while the ICS2000 provides
flexible interworking between IP, ATM and TDM circuits for both
trunking and access applications. The architecture supports a high
performance integrated call management function in the ICS2000,
as well as an MGCP-based application server supporting basic Class
5 features. In addition, the solution works with a number
of third-party SIP-based application and feature servers to facilitate
the delivery of advanced services and applications to subscribers.

Linking IP and PSTN Networks
The ICSP service proxy acts as a service mediation point between
SIP and AIN domains, linking applications from IP to the PSTN and
extending network resources to third-party application
servers through open standards, such as SIP. The service intelligence
of the ICSP, combined with the deployment-hardened ICS2000 media
gateway and other elements of the Distributed Softswitch
Architecture, provides unparalleled time-to-market, performance,
cost and interoperability benefits to service providers.
ICSP Service Intelligence
The ICSP provides distributed routing and service intelligence for a network of ICS2000s
and application servers. Screening, blocking, number translations and routing functions
are provided to other network elements via the ICSP, and specific services are
applied to a call via
the ICSP based on classification of the inbound call that fits a predefined profile.
The Knowledge Base for Carriers
The ICSP aggregates service data typically stored in multiple switches, Service Control Points (SCPs) and network databases, allowing for simplified network operations and scalable execution of large call volumes. The ICSP is also able to route calls from a packet network to the PSTN and from the PSTN to a packet network, directing the call processing through the most efficient path in a large, distributed network.
PSTN endpoints on the ICS2000 media gateway are represented by
the ICSP to applications as a set of fully managed SIP endpoints.
For calls originating from the PSTN and terminating in the packet
network, the ICSP performs a route translation to determine which
application element is managing the terminating endpoint. For calls
originating in the packet network and terminating in the PSTN, the
ICSP first acts as a redirect server to direct the call to the best
gateway interface, then performs service selection functions based
on the call profile. This simplifies provisioning and allows the
service provider to protect and control the details of the network
topology.
Simplified Operations
Service related data, typically stored in multiple switches, SCPs
and network databases, can be aggregated into a single ICSP service
proxy, greatly simplifying network operations. Multiple ICSPs can
be distributed in a network, providing the advantages of distributed
processing with the benefits of central administration.Service providers
can manage all service data centrally through the ICView element
management system, easily provisioning associations with ICS2000
media gateways in the network.
Unrivaled Scale, Performance and Availability
The ICSP operates independent of call state and communicates with
other network elements using standard protocols, such as SIP, reducing
network complexity and eliminating potential network bottlenecks.
The ICSP architecture allows flexible deployment and eliminates
the need for 1:N topologies required in typical master-slave softswitch
architectures. ICS2000 media gateways control load balancing between
ICSPs through a "round robin" or primary and backup mechanism.
One ICSP supports a network of ICS2000s and call-processing capacity
is increased linearly and economically with additional servers.
The ICSP can also be deployed in redundant clusters or distributed
geographically for maximum network flexibility. Load balanced N+k
deployment supports extreme scale, performance and availability
on the ICSP platform within Convergent Networks'-based networks.
OAM&P
The network can be managed both directly and remotely via the network element's
command line interface and the ICView management system. The command line interface is
ideal for basic maintenance and emergency recovery via a low-speed connection, although
all management functions,
including a flexible scripting capability, are available in this interface for comprehensive
administration. The ICView management system provides centralized control of all components
in the network
via a user-friendly Web interface, and integrates with carriers' OSS to ensure backoffice
interoperability for fast service deployment.
