The Parlay network API specification

M J Yates and I Boyd

New business opportunities have emerged for network operators to offer a new generation of interfaces directly to solution providers that expose information and control in various intelligent networks. The paper describes the commercial rationale and operational benefits of these application level interfaces. The Parlay Group has defined application programming interfaces (APIs) to expose network capabilities including wireline, mobile, IP QoS, and messaging to external enterprises. The Parlay Group and the API specification are described, together with an illustration of how the API could be used to create an enterprise workflow solution that integrates capabilities in different networks.
