In computer networking, the Application Session Controller (ASC)
network element
In computer networks, a network element is a manageable logical entity uniting one or more physical devices. This allows distributed devices to be managed in a unified way using one management system.

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
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 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
application platforms and fully enable them to leverage their network assets to offer converged applications across ever evolving networks.
