混合光纤 同轴电缆网络由于具有近 1GHz的用户接入频带而被视为仅次于光纤到户的宽带数据接入方式。但由于环境射频噪声等因素的影响导致数据传输服务的误码率增大 ,使得数据服务提高受到一定的限制。分析混合光纤 同轴电缆的数据传输特性 ,改进传输控制协议的数据传输端到端的可靠性包装机制 ,在网络前端引进代理服务器 ,可以充分发挥该接入网络的高数据传输率潜力 ,特别可提高远端的数据传输服务。
Hybrid fiber coaxial cable networks are considered second only to FTTH broadband data access due to their nearly 1-GHz user access frequency band. However, due to the impact of environmental radio frequency noise and other factors, the bit error rate of data transmission service increases, making data services subject to certain restrictions. Analyzing the data transmission characteristics of hybrid optical fiber coaxial cables and improving the end-to-end reliability packaging mechanism of transmission control protocol, the introduction of proxy server at the front end of the network can give full play to the high data transmission rate potential of the access network, and in particular improve Remote data transfer service.
