The '''Application Session Controller''' (ASC) [[network element]] resides at the [[application layer]] and sits between the application layer and the [[core network]] to provide and manage [[Connectivity (computer science)|connectivity]] to the evolving [[telecom]] [[network]]. It insulates the application [[server farm]] from the network below via a programmable network abstraction engine, thereby providing the application specific call-control functions independent of each network. The ASC incorporates a number of open standard [[Application programming interface|APIs]], plus the signaling, media, and the feature inter-working between disparate networks that converged and consolidated applications require. It is scalable to support tens of millions of subscribers via a single system or via clustering and provides the necessary calls per second / transactions per second required for large-scale multi-network environments.

As Communications Service Providers continue to deploy new network assets and technology at an increasingly rapid pace, achieving feature [[Transparency (computing)|transparency]] becomes very challenging. The benefit of creating a solution to ensure feature transparency will provide subscribers application feature parity across multiple networks, enable the service providers to consolidate their [[Computing platform|application platforms]] and fully enable them to leverage their network assets to offer converged applications across ever evolving networks.
