摘要
随着互联网业务的快速发展,用户对互联网接入带宽的需求持续增长,对HFC网络的承载能力要求也随之提高。用户数量不断增长、接入带宽持续增加、基础设施等因素的制约,对传统DOCSIS宽带网络架构提出了更多挑战。另一方面,各级政府、基础电信运营商大力推进FTTH全光接入网络,基于PON技术的接入速率达100M级的宽带产品迅速推广,对广电运营商造成了很大的市场竞争压力。所以,如何在现有网络基础上,研究网络改造升级的快速部署方案,抢占市场份额,持续发展,显得非常重要。本文通过对现有终端、机房、光缆、频点等技术资产的充分评估,兼顾可实施性、经济性、持续发展等原则,研究制定了集中式CMTS+分布式CMC+FTTH混合宽带接入网建设模式;通过公司实际案例,实现了接入带宽的快速提升和向光纤接入逐步演进的目标,解决了快速部署高带宽业务的接入难题。
Nowadays, with the development of broadband technology, we have seen a continuously growing need for access network bandwidth. To meet this requirement, HFC network need to be improved. The original DOCSIS network is challenged by several factors such as the growing number of subscribers, the expanding bandwidth, and the infrastructure resource shortage. Meanwhile, the government and telecom operators are pushing hard to expand PITH network. 100Mbps products based on PON spread over the market, and impact seriously on cable operators. So, how to quickly upgrade the existing cable network and to grab market share is much more important than ever. This paper suggests a construction model of sustainable integrated-CMTS ＆ distributed-CMC ＆ FTTH hybrid broadband access network, which helps to rapidly implement the high speed and multi-service broadband accessing.
