Application programming gap between telecommunication and internet [Next-Generation Telco IT Architectures ]

As awareness of next-generation networks in the telecommunications industry increases, the possibilities of novel services for integrating web applications in the Internet and new IP-based telecommunication networks are gaining attention. However, the industry is still seeking an ideal application programming interface design to publish telecommunication functions with web service technology. The industry is also unsure whether supplying not only APIs but SDKs is really necessary, even though there is a vague consensus that SDKs enable programmers to create novel web-telecom applications. Therefore, we conducted a quantitative experiment with human participants to investigate the productivity of web-telecom application programming with Parlay X and an SDK. From the results, we discuss the inevitable problem that web-telecom APIs and SDKs, in handling stateful and asynchronous communication with web service technologies, confuse programmers.
