Open API for QoS control in Next Generation Networks

Content Provider	CiteSeerX
Author	Lee, Samson
Abstract	Opening up telecommunications networks allows operators to develop and deploy new services that utilize the underlying capabilities of the network. Open Service Access and the Parlay APIs are gaining wide industry acceptance for basic service capabilities such as call control and user location. However, next generation services will require the use of additional advanced service capabilities such as Quality of Service, multicasting and VPN provisioning. This paper focuses on Open APIs for Quality of Service control, and analyzes the existing Parlay Connectivity Manager as an interface to the expected requirements based on recent drafts from ETSI TISPAN’s Resource Admission Control Subsystem. We describe the strengths and weaknesses of the existing API specifications and provide suggestions about changes that are needed to improve the specification. Furthermore, we describe our efforts to date in implementing a prototype of the specifications and experience in utilizing the prototype to develop an example QoS-aware application. 1 UTS:
