As the content-rich services which demand tremendous bandwidth proliferate, service providers must adapt to the trend quickly so as to meet not only the current demands but also the future needs of their customers. The hybrid fiber-copper deployment facilitates and complements Fiber-to-the-Home (FTTH) strategy in which optical fiber is gradually brought closer to the consumer, and emerging G.fast (Fast Access over Subscriber Terminals) technology is used for the remaining copper network. The deployment of ultra-broadband hybrid fiber copper access networks introduce significant challenges in the service provisioning, network operation, and management which need to be mitigated. In this paper we first address selected significant management issues such as G.fast management approaches, provisioning point comparison, and the flexible service provisioning for G.fast. We then present the design of the integrated and automated provisioning systems to support the diversity of services for hybrid fiber copper networks. Such integrated systems will speed up the end-to-end quality assured service delivery, reduce the operational expenditure (OPEX), and result in higher customer satisfaction.

Over the last decade, advances in Internet technology brought about the proliferation of Internet-based multimedia applications, particularly known as Internet Protocol Television (IPTV) services. In the large-scale, heterogeneous, multi-vendor, and increasingly complex and multi-functional IPTV networks, the quality assured provisioning is one of the key challenges to service providers. To support IPTV services across such a complicated IPTV network, we first address some selected significant provisioning issues such as virtual LAN (VLAN) based service binding, the integration of robust quality of service (QoS) mechanisms, and multicast flow management. Moreover, we leverage the Virtual Private LAN Service (VPLS) to build a large-scale, cost-effective, and reliable network. Finally, we present the design of the integrated and automated quality-assured provisioning systems for the largest commercial IPTV network in Taiwan. The integrated systems support the diversity of services and across all of the enabling IPTV network devices. The proposed systems speed up the end-to-end quality assured service delivery, reduce the operational expenditure (OPEX), and result in higher customer satisfaction.

In this paper, a 3-band wavelets transform, which has two main characteristics of primary visual sense: Gabor function model and 3 scale transform, is used to simulate the processing of simple cell in the visual cortex. Because of higher order statistics properties of the environment, the input response under the multiresolution analysis is decomposed linearly by using the independent component analysis (ICA) and the basis functions at each resolution are extracted. The experimental results indicate that our model with wavelets characterization could simulate the response characteristic of primary visual sense preferably.
