摘　　要：采用以太网技术已成为低压变电站自动化系统通信方式的发展趋势,而低压变电站自动化系统的间隔层设备硬件平台配置较低,难以引入实时操作系统及其TCP／IP协议栈。地址解析协议(ARP)是TCP／IP协议栈的基本协议。文中分析了ARP,研究其在低硬件配置平台上的实现方法,提出使用哈希表形式的ARP信息表,组织管理IP单播地址和对应的以太网媒体访问控制 (MAC)地址的映射,给出了哈希表的哈希函数和利用ARP监测网络故障的方法。The adoption of Ethernet technology as （SAS） is a new trend. As the equipment located at the communication mode in a low voltage substation automation system the bay level of low voltage SAS is arranged low, it is difficult to download the real-time operation system （RTOS） and its implementation of TCP/IP. The Address Resolve Protocol （ARP） is the basic protocol of the Ethernet communication protocols. An analysis is made of the ARP and its implementation on a lower hardware configuration platform. The idea of the Hash table is used to organize the ARP information table, which manages the mapping from the Internet Protocol （IP） unicast address and the corresponding Ethernet media access control （MAC） address. Also presented in this paper is the Hash function of the Hash table with the method of applying ARP to the monitoring of network failure briefly treated.
