摘要
针对EPON+EoC+IPQAM网络中,基于应用层协议交互下行QAM通道信息时,数据封装开销大、交互次数多的问题,设计一种基于扩展ARP协议的网络寻址方案。E-ARP采用TLV编码格式,在标准ARP协议中扩展EEQAM网络中调制解调和QAM通道的描述信息,并增加调制解调器和QAM通道交互过程,以实现EEQAM的网络寻址。数值分析证明E-ARP相比应用层的HTTP/XML、SOCEKT通讯,交互次数少,封装开销低,通讯效率更高,且具有良好的扩展性。
In EPON ＋ EoC ＋ IPQAM, application - layer - protocol - based to inform the terminal downstream QAM channel informa- tion, data encapsulation overhead and interactive high cost problem, this paper designed based on extended ARP protocol network addressing scheme. E -ARP uses the TLV encoding format standard ARP protocol to increase the cable TV network equipment and channel descriptions, and add a QAM channel interaction, in order to achieve EEQAM network addressing. Numerical analysis than the proof of E - ARP application layer HT＇FP/XML, SOCEKT communications, interactive fewer, lower encapsulation overhead com- munication more efficient, and has good scalability
