Research of The Index Mechanism of Management Information Base in GPON ONU

摘要

MIB which stores all the information of managed entities in GPON system is a common interface among every functional subsystem. According to using SQLite as the platform for developing MIB of ONU Management Information Base in GPON network management system,firstly this paper analyses the principle of its B+ tree index mechanism,and mainly researches its organizational structure and access process. Then based on the specific inquiries of GPON network management system,it proposes an improved B+ tree index mechanism.Finally,experiments prove that this improved B+ tree index mechanism can not only improve access speed but also increase space utilization rate,also effectively achieve the performance of the MIB,which have certain realistic meanings to implementation of GPON network management system.
