三网融合:给中国有线电视运营商的建议

2010年,中国政府宣布了整合电信、互联网和广播网络的"三网融合"计划。此计划将为有线电视运营商创造三重播放的商业机会。目前他们正准备利用已有的广大有线电视用户群和内容优势来拓展这一项市场新机遇。中国的有线电视运营商比起他们的竞争对手,电信运营商来说,在付费电视市场有天然的优势。中国的宽带市场普及率仍低,未来还有很大的成长潜力。因此宽带接入将是有线电视运营商竞争角逐的第一个新市场。

On management of CATV full service networks: a European perspective

The CATV network operators hope to offer digital services and evolve their networks to full service networks. There are many hurdles for them at the moment in the transition to a digital network and digital service offering from the current analog-based technology. Key to the success of the transition will be a well-integrated and capable management system to allow CATV operators and service providers to control the network as well as the services they will offer. The CATV operators need to agree on a common data communication infrastructure and plan how their new digital services will be offered to subscribers without disrupting the current customer base of analog service users. The choice of network technology and data communication protocols will have a strong influence on the network management technology chosen. A vital element for the provision of a common open communication architecture as well as for the purposes of network management is that the IP is used. The adoption of existing standards is vital in order to establish a fast route to open network management for CATV networks. It is possible that CATV operators and service providers will have to integrate existing SNMP management systems and TMN/OSI management, with newer integrated service management systems based on TINA and implemented on a CORBA platform. There is a strong need to address security issues before any of these technologies can be deployed for service. There is currently investment (deployed systems and research) which uses each of the technologies mentioned, so these technologies will need to coexist. This article highlights the differences between the North American and European network architectures, and outlines the European network and network management scenario. This is based on the authors involvement in a Pan-European CATV project, Integrated Broadband Communication over Broadcast Networks-IBCoBN

Managing a broadband environment: “you can't buck themarket”

Demand for bandwidth seems unstoppable, and investment in network infrastructure is massive. There is a desire that network operators be able to manage these networks in an efficient manner, with flexibility to support new customer service opportunities faster and cheaper. Network operators are looking to standards to help them meet this challenge. The telecommunications management network (TMN) model, so effective in describing how management information must support needs at the element, network, and service levels, provides a good starting point. However, if the supporting standards are not developed and used wisely, a TMN approach can have the opposite effect of adding cost and removing flexibility. Technology-specific “stovepipes” may make it impossible to manage services across a range of technologies. The authors express their views on the need for a service-driven approach to standards implementation. They point out specific challenges operators will face as they approach their management systems' needs for broadband services, and encourage service providers and network operators to take a more proactive role in defining their needs     

SBS在ASON中的管理和实现

随着数据业务的爆炸式增长,如何在光网络中有效地利用宝贵的带宽资源已经成为研究人员所关注的焦点.基于时间分配带宽业务(SBS)是自动交换光网络(ASON)中的一种新型业务,可以被认为是传统的按需分配带宽(Bandwidth on Demand,BoD)业务的一种具体实现,SBS的出现既可以有效地为运营商节省宝贵的带宽资源,又可以降低用户的成本开销.文章从管理模型、实现方法以及社会价值等几个方面对SBS进行了详细的描述.     

基于DOCSIS技术的新型HFC网管系统

对HFC网络进行统一监控和管理是广电运营商提升服务质量和运维效率的必要手段。长期以来,国内基于《HFC网络设备管理系统规范》建设的HFC网管系统普遍存在成本较高、回传信号干扰严重的问题。本文在对传统HFC网管系统架构分析的基础上,提出了基于DOCSIS技术的新型的HFC网管系统架构。该系统架构利用广电网络已有的双向网络基础设施完成HFC光站网管数据的回传,实现对HFC网络设备的管理。该方案结构简单、管理方便、网管数据通道高速稳定。本文所给出的技术方案可以作为HFC网管系统建设的参考,具有现实指导意义。

Application of control plane technology to dynamic configurationmanagement

The distinction between switched and leased line services is beginning to disappear. Many network operators and suppliers are developing control plane technology for application in transport networks. This will allow faster service provisioning, particularly between network operators, and the creation of new network services. However, such systems will still require comprehensive management systems, and successful operators and vendors of the future will be those that are capable of developing operational support systems that complement the control plane with service management capabilities, automated plan and build processes, inventory management, and capacity planning. This article examines the distribution of functionality between the management and central planes for support of soft permanent and switched connections
