As the global IPTV market is growing fast, assurance of IPTV service quality becomes one of the key factors to the success of IPTV business. To deal with the IPTV service assurance issue, one of the practical approaches that the service provider can apply is to employ the state-of-the-art development technologies (e.g., NGOSS frameworks) to construct an IPTV management platform, in which a number of Operations Support Systems (OSS) can be seamlessly integrated and co-work to support the daily IPTV service operations. In this paper, an end-to-end IPTV network management architecture was depicted, and a unified network management system (NMS) was developed to monitor and control multi-vendor, multi-technology broadband network elements deployed in the carrier's head end, core network, access network, and home network. The in-house NMS supports loosely-coupled systems integration with other OSS based on the service-oriented architecture (SOA). Moreover, a practical approach to home network management was described to show how the NMS automatically collects a variety of IPTV-related data from set-top boxes (STBs) and then provides some useful management functions (e.g., video/audio packet loss analysis and IPTV audience rating) for the ease of service assurance and the exploration of subscribers' tastes for IPTV programs.
According to the long term vision of cloud computing, the cloud service gradually becomes a utility just like water, electricity, and telecommunication. Although the cloud service is supposed to greatly improve today's IT delivery model and offer potential benefits to customers by the saving of capital and operational expenditure and the greater flexibility of IT resources, cloud service providers are still facing a number of challenges such as service quality assurance and need to tackle them to gain advantage from cloud computing. In this paper, a set of cloud-centric BSS/OSS, called Cloud BOSS, was developed by adopting TM Forum NGOSS framework to support the management and operation of cloud services in a more efficient way. Cloud BOSS provides a self-service and self-management portal for customers to subscribe and manage cloud services on an "on-demand" basis. It also supports the integrated management of heterogeneous cloud resources on the common platform. To assure the quality of cloud services, Cloud BOSS provides service problem and quality management functions which proactively monitors the operation status of the cloud service from the viewpoint of customers. Currently, Cloud BOSS is on-line and used to support the operations of CaaS services offered by Chunghwa Telecom.
