Centralized network management used in active EOC master
LV Yu-bi · Electronic Design Engineering · 2015
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 Power PC 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.
