Abstract
The role of open Application Programming Interfaces (APIs) and protocols for advanced service provisioning and the corresponding state of the art are the main subject of this chapter. Specifically, the role and the trade-offs in modern telecoms between open APIs and Protocols, that is, OSA/Parlay APIs, JAIN APIs and SIP, are discussed. A technical implementation analysis for each solution is presented, based on a call-related service, in order to set a common basis for the aforementioned technologies, since “voice” is a common denominator for a Fixed or Mobile Operator or an Internet Service Provider. A performance evaluation study regarding the implemented services is also presented and the chapter is summarized by interesting conclusions and related future trends.
