在3月22日?25日举行的2005全球NGN高峰论坛,没有以往那种喧哗和热闹,各大整体方案提供商的展台前也已不再是人头攒动。NGN(下一代网络)的发展,在其融合多媒体解决方案最核心部分已不再是技术,更多的将是NGN所能带给最终用户的一些全新体验,帮助运营商开发更多的业务,从而获取更高的利润回报已成为了业界的共识之后。北电融合多媒体事业部总经理AlanStoddard先生在会上表示,摆在NGN面前的将是完善产业链结构,运营商、企业用户、系统提供商等个方面需要进行更深、更广泛地合作。他介绍说,北电在过去的3年里已经部署了多个NGN网络,北电… 相似文献

The IP Multimedia Subsystem (IMS), already widely recognized as a fundamental core component of Next Generation Networks (NGNs),
enables proliferation of a huge variety of value added services. Simultaneous to the emergence of triple play services there
is a strong need for establishing standardized methodologies for service fulfillment and assurance, maintaining service execution
parameters at advertised levels. Traditional Operations Support Systems (OSS) are not adequate for managing NGNs. This work
shows experiences gained from implementing OSS for NGNs. It describes a solution that combines extensive NGN development expertise
with a new generation, of policy-based, service oriented OSS solutions in order to provide enhanced levels of automation and
reliability to the NGN service delivery and session control environment. Primary focus of this approach is put on service
assurance and service fulfillment mechanisms for remote monitoring, automated control and configuration of standard compliant
IMS infrastructures, such as the Open Source IMS Core (OSIMS) based Open IMS Playground. This work describes state of the
art NGN OSS design principles and knowledge attained by integration of standardized fault management as well as service and
subscriber provisioning procedures showing how the full cycle from service deployment to service advertisement to service
execution can be delivered in an automated way.

Research teams and IT service providers are continuously increasing the degree of Automation in Hybrid IT environments spanning multi-provider Clouds as well as traditional IT. Automation and Cognitive Systems are widely regarded as the foundation for improving the productivity as well as the quality of Service Delivery. At the same time, Hybrid IT deployments are being subject to a variety of challenges in large deployments on a global scale. Based on our experience of running a service practice that delivers IT Service Management in Hybrid IT environments to customers worldwide, this paper will review the challenges and directions in implementing Integrated Network, Systems and Service Management technologies and point out gaps encountered in current tools and implementations. This is fueled by the desire of Service Providers to evolve Automation from a development activity to an approach focusing on recording and storing the practices of the best system administrators and further on to a cognitive activity where the management system learns over time which actions need to be undertaken under a given set of circumstances. By means of real-life examples, we identify candidate concepts and technologies that will help us build the next generation of Integrated Network, Systems and Service Management. 相似文献
