Course 214: Open Services Architecture (OSA)/Parlay Fundamentals

The OSA (Open Services Architecture) / Parlay APIs allow the Internet service model to be introduced into the telecom networks. Parlay is an open multi-vendor consortium formed to develop open technology independent APIs enabling ISVs, network device vendors, software developers, service providers, ASPs and enterprises to create applications that will run across multiple carrier networks.

This course provides an introduction to OSA/Parlay and related open network APIs. It introduces the drivers towards such APIs and their relationships, provides an overview of the API structure and functionalities, and explains the their realisation in different network environments.

Parlay/OSA concept, market trends and requirements, who is using Parlay, what they are using Parlay for, and how it is deployed are discussed.
