摘要
分析了三网融合条件下广电接入网的需求,提出EoC是适合广电运营商双向网改的重要技术。对比WiFi降频、C-DOCSIS和HomePlug AV等主流技术,从网络拓扑、物理层指标、数据链路层指标、系统指标等多方面进行分析。结合国家广电总局的要求和未来组网运营需求,对EoC技术的发展趋势进行了分析,认为EPOC和HiNOC技术将有非常良好的应用前景。
This paper Analyses the CATV access networks requirement of three-network convergence. EoC （ Ethernet over Coax） is the most important technology suitable for CATV carrier. Then Compares main preva- lent technologies such as WiFi（802.11 n）, C-DOCSIS and HomePlug AV. Network topology, physics proper- ties, MAC function and system performance has been analyzed. Combining with the requirement of the state administration of film and television, the paper forecasts that the EPOC and HiNOC are promising technolo- gies.
