摘　　要：由于传统的有源EOC局端通常采用单个CPU芯片管理单个EOC协议芯片的方式,存在CPU资源利用上的浪费。本文介绍了基于集中式管理的有源EOC网管系统。该系统网管单元CPU由Freescale公司的MPC8247芯片构成,这是一款基于Power PC?内核的处理器,结合Broadcom公司的千兆交换芯片BCM53115,构建集中式网管硬件平台,可以向上提供5个千兆以太网接口,最多可以同时管理4个EOC协议芯片,使得CPU的利用率得到很大的提升。该系统遵循广电网络的MIB库规范,具有软件框架灵活,运行稳定可靠,功能丰富实用等特点,适用于基于SNMP协议的广电网元的日常管理。本文给出了系统的硬件组成框图和软件流程。Because the traditional active EOC master typically uses single CPU chip to manage single EOC protocol chip, which is a waste of CPU resource utilization. This paper describes an active EOC network management system based on a centralized management. The CPU of the network management unit is MPC8247, which is a PowerPC kernel-based processor of Freescale. Combined with the gigabit switch chip BCM53115 of Broadcom, it could build a centralized network management hardware platform which can provide five GE ports and can simultaneously manage up to four EOC protocol chips, so the CPU Utilization is greatly improved. The system follows the MIB specification of broadcast ＆ TV network. With flexible software framework, reliable, feature-rich and practical function features, the system is suitable for daily management application of the broadcast ＆ TV network based on SNMP protocol. The paper provides the diagram of hardware ＆ software of the system.
