Application Session Controller (ASC) - a network element that sits between the application cloud and the converging network/ control layer to provide and manage connectivity to the evolving network for multiple applications. It is a purpose built, highly scalable, carrier grade network element that enables legacy, intelligent network (IN), IP and next generation IMS applications to be immune from the ever evolving network. It insulates enhanced applications from the network via a programmable network abstraction engine, thereby providing the application consistent call/session control functions independent of each network.
Large Scale Voice Centric Application Deployments
A service provider needs to deploy a 20 million subscriber VM solution to replace an existing legacy solution. They must migrate subscribers from the legacy network to the new in a seamless fashion and ensure that the network layer can handle up to 150 calls per second. They also require the ability to manage new protocols as they arrive and ensure the network layer is future-proof so new applications can be added at a later date.

Multi-App Deployments
Service Providers(SPs) have applications that are optimized for a specific network, however when a network evolves, either through an acquisition, scheduled upgrade, or network build-out, SPs are faced with the challenge of how to create feature transparency across disparate networks. The core network has been built with the purpose of connecting subscribers, not applications. Throw multiple networks into the equation, and this complexity is highly intensified. Applications need and deserve the same flexibility as is given to subscribers by the core network to keep pace with the demands of those same subscribers.

Integrating Legacy Apps into IMS
IMS represents a new age in telecom networks that promises the delivery of robust multimedia services across diverse networks. However this promise is being stalled by the problem of creating feature parity between legacy networks and the new IMS network. Today IMS networks have only the potential of being more feature rich than their legacy predecessors.

Web 2.0 / Application Mash-Up Solutions
The differentiation between voice and data networks is becoming blurrier and blurrier every year. Blend this fact with the potential of applications built by IT developers for voice networks, and the possibilities are endless. The promise of leveraging a huge ecosystem of developers to build voice centric applications is on the edge of becoming reality. All this potential is based on the promise that IT developers will be able to quickly understand and build new applications enabled by concealing extremely complex voice network functions behind by a highly abstracted and easily consumable web services API.
