宽带接入网关键技术研究进展

Key technologies and recent progress of broadband access networks

宽带通信网包括高速光纤传输骨干网和宽带接入网(BAN),但两者发展极不平衡。尤其是BAN在保密性与私有性、成本与能耗、融合兼容性及速率与带宽等方面亟待突破。综述了BAN的研究进展,分析了BAN理论与技术的发展趋势及关键问题,探讨了增强BAN的保密性与私有性、降低BAN的成本及提升BAN的融合兼容性等问题。

Broadband communication networks include both high-speed optical fiber transmission backbone networks and broadband access networks （BAN）, but developments of the two kinds of networks are very uneven. Particularly, several challenges of BAN such as speed and bandwidth, security and privacy, cost-effectiveness, energy consumption and integration need to be addressed. In this paper, according to the international research reports, a brief overview of the research progress of BAN is presented, and the trend in technology development and key issues of BAN are indicated. At last, the security and privacy enhancement, the cost reduction, the integration and compatibility improvement of BAN are summarized and discussed.
